xii Introduction
• The Fiery Color Reference Glossary defines words in bold—for example, output
profile—that appear throughout this manual. Color terms and concepts, such as
“color space,” “spot color,” “gamut,” and “source profile,” are used throughout this
manual. If you are new to desktop color, or if any terms are unfamiliar, check the
Glossary.
Key features of ColorWise
ColorWise is the color management system (CMS) built into the GA-1121 and
designed to provide both casual and expert users with the best color output for a
variety of purposes. The ColorWise default settings provide high-quality out-of-box
color from many Windows and Mac OS applications. This allows casual users to
achieve quality output without knowing about or changing any color settings on the
GA-1121.
For consistent color, calibrate the GA-1121 on a regular basis. ColorWise Pro Tools
include an easy-to-use calibrator, which allows you to calibrate using either the
scanning unit that is part of the copier/printer or a spectrophotometer or
densitometer (see Chapter 2).
ColorWise features allow you to modify printing results. Depending on your particular
needs, you can:
• Set the behavior of CMYK printing to emulate DIC, Euroscale, and SWOP offset
press standards.
• Match PANTONE and other spot colors for the best match when printed using
four-color press conditions or when printed using presses with extra, custom plates.
• Select a color rendering dictionary (CRD), also called a rendering style, for RGB
printing. CRDs allow for rich, saturated printing of presentation graphics; smooth,
accurate printing of photographs; and relative or absolute colorimetric rendering for
specialized needs.
• Define the source of incoming RGB color data for better screen matching and
provide for better color conversion of RGB data with no source information.

xiii Key features of ColorWise
• Define whether RGB data is converted into the full gamut of the copier/printer or
whether it is first converted into the gamut of another device, such as a press
standard. This feature is helpful for making one device behave like another. It is also
useful for evaluating the appearance of the RGB file under different printing
conditions without having to reprocess the RGB data each time.
ColorWise color management (ColorWise) offers an open color architecture, allowing
users to customize the GA-1121 to meet new printing needs as they arise. ColorWise
supports ICC profiles, which are industry standard color profiles that describe the
color behavior of a device. Downloading ICC profiles to the GA-1121 enables the
print colors from a particular monitor or a scanner. In addition, you can create
customized ICC profiles for the copier/printer.
ColorWise also allows you to use any Status T densitometer by importing data in a
standard file format (see Appendix B). In this case, it is important to note that the
quality of the instrument used will determine the quality of the calibration.

particular needs. They provide descriptions of the preset ColorWise default settings
and cover additional options for users who need to customize ColorWise.
Chapter 1:
GA-1121 Color
Management
For information on PostScript Level 2 or 3 printer drivers, see page 1-16. The section
also contains information on the capabilities of printer drivers and instructions for
setting color options with the PostScript drivers for Windows and Mac OS computers.
NOTE: Many of the color management options described in this chapter are only
available with the PostScript driver, not the PCL driver.
Managing color on the GA-1121
To modify GA-1121 printing behavior, do any of the following:
• Select ColorWise options for an individual print job using menus that appear in the
printer driver.
• Select most ColorWise options as server defaults from the Color Setup application
• Select some ColorWise options, particularly default ICC profile settings and
calibration options, from ColorWise Pro Tools. These options include default
Simulation Profile (see page 1-12), CMYK Simulation Method (see page 1-13),
Appear in Driver as (see page 3-7), default Source Profile (see page 1-11), RGB
Separation (see page 1-14), and associated calibration set (see page 2-4).
Applications can generate color data for the GA-1121 in many different color spaces.
The most common type of color data produced from office applications is RGB, while
prepress applications generally produce CMYK data. Desktop applications can also
generate spot colors, such as PANTONE colors. To complicate matters, a single page
may contain a mix of RGB, CMYK, and spot colors. The GA-1121 allows users to

control the printing of these mixed-color documents with features that apply
specifically to RGB, CMYK, or spot color data. GA-1121 color management generates
CMYK data to be sent to the copier/printer.
The following diagram illustrates the print options in the GA-1121 color management
process that affect color data conversions. You can access these print options when you
send a print job to the GA-1121. Most of these options and settings are described in
subsequent sections of this chapter.

RGB Source Profile is the only color option that applies strictly to RGB color data.
The other options that affect RGB color also affect the more rarely used Lab, XYZ, and
other calibrated color spaces.
NOTE: For users who are familiar with PostScript 3 color, RGB Source Profile affects all
CIEBasedABC color spaces (if the source space is RGB). If you send CMYK data to
the GA-1121 in CIEBasedDEFG format, for example, by choosing PostScript Color
Management in Adobe Photoshop, the GA-1121 Rendering Style selection—which
normally affects only RGB data—will also affect this CMYK data.

You can specify settings for the following options by selecting print options when you
send a job to the GA-1121. Some can also be set as defaults by the administrator dur-
ing GA-1121 Setup or using ColorWise Pro Tools. Settings specified using print
options override the defaults. Some options can be used as what was purchased sepa-
rately.
GA-1121 color print option
What it does
Black Detection
On/Off
If your job consists of black-only text pages combined with a significant
number of color pages, set this option to Off.
Black Overprint
Specifies whether to overprint black text or black text and graphics placed on
colored backgrounds. Overprinting colored backgrounds eliminates white gaps
and reduces halo effects or misregistration of colors (see page 1-9). This option
is only available with the PostScript driver.
Off/Text/Text & Graphics
(Default set at Setup or with ColorWise Pro
Tools)
Brightness (PS only)
85% Lightest to 115% Darkest
Performs a color adjustment on all color channels to make the printed
output lighter or darker.
CMYK Simulation Method
Quick/Full (Source GCR)/Full (Output
GCR)
(Default set at Setup or with ColorWise Pro
Tools)
Quick simulation applies one-dimensional transfer curves that adjust output
density only. The Full simulations apply colorimetric transformations that
available with the PostScript driver.
CMYK Simulation Profile
Adjusts CMYK color data to simulate an offset press standard or a custom
color gamut defined at your site. The Match Copy setting bypasses GA-1121
calibration to match a copy made from the copier glass. Choosing None
bypasses simulation (see page 1-12). This option is only available with the
PostScript driver.

NOTE: The rendering styles associated with the PCL driver do not match those
associated with the PostScript driver.
Pure Black Text/Graphics
The Pure Black Text/Graphics option affects the printout for black text and vector
graphics on a page. Under most circumstances, leave this option set to On. When Pure
Black Text/Graphics is on, black colors generated by applications (for example, RGB =
0, 0, 0; CMYK = 0%, 0%, 0%, 100%; or K = 100%) are printed using the maximum
amount of black toner allowed by the calibration curve. This means the black text and
line art will not exhibit halftone artifacts (as long as the copier/printer is calibrated
correctly) and will not be misregistered, since there is only one toner used. In addition,
this setting eliminates blasting.
For some jobs, it is preferable to clear this option, for example, if the page includes
gradient fills that use black. The following table describes the behavior of the Pure
Black Text/Graphics option with black data defined in different color spaces.
NOTE: Use the Pure Black Text/Graphics option only when printing composites, not
when printing separations.
Pure Black Text/Graphics
Input

copier/printer.
Spot
Prints only with black toner, because spot color
simulations preserve the black channel. The actual
amount of toner used depends on the current

NOTE: PostScript applications (such as QuarkXPress) may convert elements defined as
RGB = 0, 0, 0 to four-color CMYK black before sending the job to the GA-1121.
These elements are not affected by the Pure Black Text/Graphics option. For details,

see the application notes. Also, black text and line art defined as RGB = 0, 0, 0 in office
applications (such as Microsoft Word) are converted to single-color black (CMYK =
0%, 0%, 0%, 100%) by the Microsoft PostScript Level 3 driver for Windows
2000/XP. To print this single-color black at the maximum toner density of the
copier/printer, set the Pure Black Text/Graphics option to On.
NOTE: This feature is not available with the PCL driver.
Black Overprint
The Black Overprint option allows you to specify whether or not black text or
text/graphics—defined as RGB = 0, 0, 0, or as CMYK = 0%, 0%, 0%, 100%—
overprints colored backgrounds.
• Text—Black text overprints colored backgrounds, eliminating white gaps and
reducing halo effects or misregistration of colors.
• Text & Graphics—Black text and graphics overprint colored backgrounds,
eliminating white gaps and reducing halo effects or misregistration of colors.
• Off—Black text or text/graphics knocks out colored backgrounds.
NOTE: PostScript applications may perform their own black overprint conversions
before sending the print job to the GA-1121.
One example of how you might use this setting is with a page that contains black text
on a light blue background. The background blue color is CMYK = 40%, 30%, 0%,
0% and the black text is CMYK = 0%, 0%, 0%, 100%.
• With Black Overprint set to Text or Text & Graphics, the final text or text/graphic
portions of the page are overprinted, or combined with the underlying colors. Black
colors generated by applications (for example, RGB = 0%, 0%, 0%; CMYK = 0%,
0%, 0%, 100%) are printed using the maximum amount of black toner allowed by
the calibration curve. This means that black text and line art will not exhibit
halftone artifacts (as long as the copier/printer is calibrated correctly). There is no
transition in the cyan and magenta toners, and the quality of the output is improved
since it will not show artifacts near the edges of the text or text/graphics. The option
also works with text defined in the RGB color space, that is RGB = 0, 0, 0.

• With Black Overprint Off, the border of the text or text/graphics is on an edge that
has cyan and magenta toners on one side (outside the text) and black toner on the
other side (inside the text). This transition may cause visible artifacts because of the
practical limitations of the copier/printer.
NOTE: This feature is not available with the PCL driver.
Spot Color Matching
The Spot Color Matching option provides automatic matching of spot colors with
their best CMYK equivalents.
• On—The GA-1121 uses a built-in table to generate the closest CMYK matches of
spot colors your copier/printer can produce. (New tables are generated when you
add new output profiles.) With the Spot-On (available as Option), the GA-1121
uses the CMYK matches determined through Spot-On (see page 3-18).
• Off—The GA-1121 uses CMYK equivalents defined by the spot color manufacturer,
that include spot color libraries.
For jobs that include spot colors, set Spot Color Matching to On unless you are
printing press simulations. In that case, set Spot Color Matching to Off and choose the
appropriate CMYK Simulation setting (see page 1-12).
For PDF jobs that include spot colors and where the spot colors are not included in the
built-in table, setting Spot Color Matching to On retains the spot color originally
specified. The GA-1121 references the built-in table to generate the closest CMYK
matches of the original spot color.
NOTE: Use the Spot Color Matching option only when printing composites, not when
printing separations.
Spot Color Matching and the PANTONE Coated Color Reference

• On—The GA-1121 uses a built-in table or, with the Spot-On (available as Option),
the Spot-On color dictionaries (see page 3-18) to generate the best matches of the
PANTONE colors that your copier/printer can produce. The PANTONE number
is printed below each swatch.
• Off—The GA-1121 prints swatches using the CMYK values recommended by
Pantone, Inc. (and used by applications that provide PANTONE color libraries).
The CMYK values used to generate the color, as well as the PANTONE number of
the color, are printed below each swatch. These CMYK values are printed through
the selected CMYK Simulation and Output Profile settings.
NOTE: This feature is not available with the PCL driver.
RGB Source Profile
The RGB source profile setting allows you to define the characteristics of the RGB
data in your document so the appropriate color conversion can occur on the GA-1121.
Commonly used monitor color spaces are available from the printer driver and from
the ColorWise Pro Tools Profile Manager. For special needs, use ColorWise Pro Tools
to download custom monitor or scanner profiles.
When you specify a setting other than None for the RGB Source Profile, the GA-1121
overrides source color space definitions or profiles that other color management
systems may have specified. For example, if you specified a ColorSync System Profile
on your Mac OS computer, the RGB Source Profile setting overrides it. In cases where
you do not want this setting to override another specified source color space, choose
the None setting.
When you specify a setting other than None for the RGB Source Profile—since the
color space definitions are overridden—the output from the GA-1121 is consistent
across platforms. The GA-1121 RGB Source Profile options are:
• EFIRGB specifies an EFI-defined color space recommended for users who have no
detailed information about their RGB data.
• sRGB (PC) specifies the industry standard definition for a generic Windows
computer monitor.
• Apple Standard specifies the definition of all standard Mac OS computer monitors.

• Other allows you to specify custom RGB source settings. If you choose Other as the
RGB Source Profile setting, you must choose settings for the Gamma, Phosphors,
and White Point options.
• Sources 1-10 specify the definitions you download as RGB source profiles. For more
information about downloading RGB source profiles, see page 3-4.
If you are printing with the PostScript driver from a Windows computer and have
Two-Way Communication enabled, the name of each downloaded profile is
represented in the RGB Source Profile setting menu. If you are printing with the
AdobePS driver from a Mac OS computer, downloaded profiles appear as Source-1
through Source-10. For more information on Two-Way Communication, see the
User Software Installation Guide.
• None instructs the GA-1121 to allow the RGB sources you defined elsewhere, such
appearance of colors will not be independent of the file type. For example, RGB EPS
files will look different from RGB TIFF files.
With RGB Source set to None, PostScript RGB data that contains a source color
space definition is converted using the CRD specified by the Rendering Style option
(see page 1-7). Non-PostScript RGB data and PostScript RGB data that does not
contain a source color space definition are converted using a general undercolor
removal (UCR) conversion method.
NOTE: This feature is not available with the PCL driver.
CMYK Simulation Profile
The CMYK Simulation Profile print option allows you to print press proofs or
simulations. This setting specifies the offset press standard or other color printing
device that you want to simulate. This option affects CMYK data only.
With the Windows printer drivers, you can also view an unlimited number of custom
Full simulations created using ColorWise Pro Tools. On Mac OS computers, you can
view up to 10 Full custom simulations. The number of custom simulations is limited
by the disk space on the GA-1121.

Communication, see the User Software Installation Guide.
The None setting sends your original CMYK data to the copier/printer in its calibrated
state, without conversions to simulate another printer.
The CMYK Simulation Profile setting you specify depends on the press standard for
which the CMYK data was separated.

about downloading ICC profiles to the GA-1121, see “Downloading profiles” on
page 3-4.
NOTE: This feature is not available with the PCL driver.
CMYK Simulation Method
The CMYK Simulation Method allows you to define your preferred
CMYK-to-CMYK conversion technique.
• Quick applies one-dimensional transfer curves to adjust output densities in the cyan,
magenta, yellow, and black channels. This technique leads to pleasant color output
from your copier/printer because pure primary colors are not “contaminated” by
other colorants. While it is the fastest simulation method and perfect for drafts,
avoid using it for final documents that will be used as press proofs. Other techniques
offer more color simulation accuracy, which is expected by proofing applications.

• Full (Source GCR) provides a complete and accurate simulation based on colorimetric
transformations. Hues are preserved, even for primary colors. The Gray Component
Replacement (GCR) level that was specified in the original (source) document is
also preserved. Full (Source GCR) is therefore an excellent simulation technique for
the highest quality press proofing applications.
• Full (Output GCR) is also a complete and accurate simulation method based on
colorimetric transformations. Hues are preserved, even for primary colors. With this
method, the Gray Component Replacement (GCR) level that was specified in the
original document is not preserved. Instead, all CMYK data is reseparated using the
GCR level specified by the Output Profile. This simulation technique is similar to
traditional ICC color matching methods and is appropriate for most documents
designed for the press, but reproduced on your copier/printer.
NOTE: When you specify On for Pure Black Text/Graphics, and specify Full (Output
GCR) for CYMK Simulation Method, the black text and graphics in your document
are printed with 100% black-only toner.
NOTE: This feature is not available with the PCL driver.
RGB Separation
The RGB Separation option determines how RGB colors (as well as Lab and XYZ
colors) are converted to CMYK. The name of this option is meant to be descriptive,
since the option defines the color spaces that will be used by the GA-1121 to “separate”
the RGB data into CMYK values.
The two choices available for this option determine whether RGB data is converted
into the full gamut of the copier/printer (output) or is first converted into the gamut
of another digital printer or press standard (simulation). This feature is helpful for
making one device behave like another for RGB data. For example, if a high-quality
ICC profile is available for another print device, the copier/printer can simulate the
behavior of that device.
RGB Separation is also useful for prepress applications. For example, it allows you to
experiment with the appearance of an RGB scan under different press printing
conditions, without having to convert the RGB data to CMYK data for each
condition. When the desired printing condition is found, convert the file to CMYK,
using the same CMYK simulation profile you used during the experimentation.

NOTE: The RGB Separation print option should be used in conjunction with the
Output Profile or CMYK Simulation Profile print options.
• Output converts all RGB colors into the CMYK color space of your copier/printer
(when set to the printer’s default), or a customized CMYK color space for your
copier/printer (when set to Output 1-10).
• Simulation converts all RGB colors into the CMYK color space for a specified
simulation (select the desired simulation with the CMYK Simulation Profile print
option).
NOTE: This feature is not available with the PCL driver.
Output profile

ColorWise Pro Tools Color Editor to achieve particular color effects (see page 3-10). If
you do so, the new customized output profile is applied to all data in the print job.

calibration target separately (see page 3-10).
Use the ColorWise Pro Tools Profile Manager to download your own output profile to
the GA-1121 (see page 3-4). Downloaded output profiles are at first associated with
the calibration target that is tied to the default output profile. You can edit calibration
target D-Max values separately.
If you are printing with the PostScript driver from a Windows computer and have
enabled Two-Way Communication, the name of each downloaded or custom profile is
represented in the Output Profile setting menu. If you are printing with the AdobePS
driver from a Mac OS computer, downloaded or custom profiles appear as Output-1

Toner Reduction
This option minimizes the total amount of toner and reduces effects of toner blasting,
offset, or flaking. With the On setting, the maximum combined amount of toner is
240%. The Off setting reduces maximum toner coverage to 280% for Plain Paper and
Thin Paper, and 260% for Thick Paper. However, with the On setting, shadow density
in a print job may be lighter than that of a job printed with the Off setting.

Setting color management print options
Choose settings for color print options from the various panes of the AdobePS driver
dialog box. To access the initial AdobePS dialog box, choose Print from the File menu
of your application.
NOTE: The term “pane” is used to describe the different pages that appear in the driver
dialog box when you make selections from the menu at the upper-left corner of the
dialog box. Each pane presents a particular set of print options.
The AdobePS driver includes the following Color Matching options.
• Color/Grayscale—When this setting is used to print to the GA-1121, ColorWise
provides all color conversions on the GA-1121. Typically, use this option when
printing to the GA-1121.
• PostScript Color Matching—Can be used with PostScript devices, such as the
GA-1121. It provides for color conversion using a color rendering dictionary (CRD)
that is downloaded with the print job. This method requires that the file is saved as
an EPS with PostScript Color Management selected.
NOTE: If you use the PostScript Color Matching option, the driver may, depending
on the application in use, attach a CMYK source definition to the CMYK data in
your document. In such a case, the CMYK data in the document is reseparated
using a GA-1121 CRD. The destination color space for the CRD is determined by
the RGB Separation print option. When RGB Separation is set to Simulation,
CMYK data is printed according to all specified CMYK Simulation Profile and
CMYK Simulation Method settings. When RGB Separation is set to Output,
CMYK data is converted to the selected output profile’s CMYK color space.
• ColorSync Color Matching—Provides for color conversion on the host computer. This
option can be used with PostScript devices such as the GA-1121, but it is intended
for use with PostScript Level 1 devices. If you use this option, you must specify the
GA-1121 ICC profile as the Printer Profile. ColorSync Color Matching is not a
suggested color matching method because it does not work in conjunction with all
applications and requires that you disable features of ColorWise on the GA-1121.

2-1 An overview of calibration
2
Calibrating the GA-1121 ensures consistent, reliable color output. This chapter
explains how calibration works and provides instructions for all calibration procedures.
You can calibrate the GA-1121 using ColorWise Pro Tools in combination with any of
the following color measurement instruments:
Chapter 2:
Color Calibration
• EFI Spectrometer ES-1000 hand-held spectrometer
• EFI Densitometer ED-100 hand-held densitometer
• X-Rite DTP41 automatic scanning spectrophotometer
• X-Rite DTP32 automatic scanning densitometer
By connecting one of these instruments to a serial or USB port on your computer, you
can quickly measure calibration color patches and download measurements to the
GA-1121.
NOTE: To use the ES-1000 or ED-100 with a Mac OS computer, you must connect
the instrument to a USB port. You also need an adaptor to connect the ES-1000 or
ED-100 to the Mac OS computer. For more information, contact your service
technician/representative. For information on setting up and operating the DTP41
and DTP32, see Appendix A.
Another way to obtain measurements is by using the copier/printer’s built-in scanner
as part of AutoCal™ or ColorCal™, which do not require the use of a measurement
instrument and can be run from ColorWise Pro Tools or the GA-1121 Control Panel.
When choosing a calibration method, keep in mind that methods using a color
measurement instrument such as the ES-1000, DTP41, or DTP32 are generally the
best. We recommend using the ES-1000 because it captures measurements very
accurately and quickly, can be used to calibrate and profile printers using pages with
For information on advanced calibration and simulation features available with
ColorWise Pro Tools, such as editing profiles and creating custom profiles, see
Chapter 3. A format for inputting color measurements from other densitometers is
described in Appendix B.

NOTE: The procedures described in this chapter are fundamentally the same for
Windows and Mac OS computers. The main differences are the interface cable and the
port used to connect to the measurement instrument. The illustrations in this chapter
describe the Windows version.
NOTE: The term computer is used to refer to any computer running
ColorWise Pro Tools.
An overview of calibration
Calibration generates curves that adjust for the difference between the actual toner
densities (measurements) and the response expected by the output profile.
• Measurements represent the actual color behavior of the copier/printer.
• Calibration sets are sets of measurements.
• A calibration target that describes the expected behavior of the copier/printer is
contained in each output profile.
After you have calibrated the GA-1121, a calibration set is stored. This calibration set
will be used when it is associated with an output profile. Every output profile has an
associated calibration set. If you have not specified one, the calibration set associated
with the default output profile is used.
If you change the calibration after a saved job has been processed (RIPped), you do not
need to reprocess (reRIP) the job. The new calibration affects the job without needing
to be reprocessed.
NOTE: Changing calibration has the potential to affect all jobs for all users, so consider
limiting the number of people authorized to perform calibration. Set an Administrator
password in GA-1121 Setup to control access to calibration (see the Configuration
Guide).
Understanding calibration
Although most users’ needs are met by the default calibration set, the GA-1121 allows
you to choose a calibration set to customize calibration for specialized jobs.

2-3 Understanding calibration
2
Calibration allows you to:
• Maximize the color reproduction capabilities of the GA-1121.
• Ensure consistent color quality over time.
• Produce consistent output across GA-1121 servers.
• Achieve better color matches when reproducing spot colors, such as PANTONE
colors or other named color systems.
• Optimize the GA-1121 for using ColorWise rendering styles (CRDs) and CMYK
simulations, and for using ICC profiles.
How calibration works
Success in obtaining satisfactory print quality from the GA-1121 depends on many
factors. Among the most important are establishing and maintaining optimal toner
densities. The density is the measure of the light absorbed by a surface. By carefully
regulating toner densities, you obtain consistent printed color.
Even with a calibrated system, toner density is affected by service settings, humidity,
and temperature; density also tends to drift over time. Regular measurement detects
day-to-day variations in densities, and calibration corrects for them.
Calibration works by creating calibration curves on the GA-1121 that compensate for
the difference between actual (measured) and desired (target) density values. These
calibration curves are the graphic equivalent of transfer functions, which are
mathematical descriptions of changes that will be made to the initial data. Transfer
functions are often graphed as input or output curves.
The GA-1121 generates calibration curves after comparing measured values to the
final target values for each of the four toner colors. The target values are based on the
output profile specified.
Measurements
Measurement files contain numerical values that correspond to the toner density
produced by the copier/printer when it prints solid cyan, magenta, yellow, and black,
and graduated tints of those colors.

2-4 Color Calibration
2
To create a measurement file, print a page of color patches. Then measure the patches
using either a color measurement instrument connected to a computer on the network
or, if it is available, the print device’s scanner. The new measurements are automatically
downloaded to the GA-1121.
Output profiles and calibration sets
Output profiles and calibration sets define desired calibration results. One or more
output profiles and calibration sets are provided with the GA-1121. When you
calibrate the GA-1121, select the calibration set that corresponds to the typical
printing jobs at your site. This same calibration set can be associated with one or more
output profiles. For more information on output profiles, see page 1-15.
Scheduling calibration
In general, you should calibrate the GA-1121 at least once a day, depending on the
volume of print jobs. If it is very important to maintain consistent color, or if the
copier/printer is subject to wide fluctuations in temperature or humidity, calibrate
every few hours. For optimal performance, calibrate whenever there is a noticeable
change in print quality.
If you need to split a print job into two or more batches to be printed at different
times, it is especially important to calibrate before printing each batch. You should also
calibrate the GA-1121 after copier/printer maintenance.
NOTE: Because printed output from the copier/printer is very sensitive to changes in
temperature and humidity, the copier/printer should not be installed near a window or
in direct sunlight, or near a heater or air conditioner. Paper is sensitive to climate
changes as well. It should be stored in a cool, dry, stable environment, and reams
should remain sealed until they are needed.
To monitor print quality, print the following color reference pages:
• Color Charts from the Control Panel (see the Configuration Guide)
• Color Charts from Command WorkStation (see the Job Management Guide)
• Color reference pages included with the user software (see the User Software
Installation Guide)

2-5 Using Calibrator
2
All these pages include fully saturated color patches and pale tints of cyan, magenta,
yellow, and black. Images with skin tones offer a very good basis for comparison. Save
and compare pages you printed at different times. If there is a noticeable change in
appearance, calibrate the GA-1121.
When you examine the Test Page, all color patches should be visible, even though they
may be very faint in the five percent and two percent range. Each color’s patch set
should show uniform gradation from patch to patch as the color lightens from 100
percent to zero percent.
If the solid density patches (100% cyan, magenta, yellow, or black) look less saturated
with time, show the pages to your copier/printer service technician to determine
whether adjusting the copier/printer can improve output.
Checking calibration status
To verify whether the GA-1121 is calibrated, which calibration set and output profile
were used, and when the copier/printer was last calibrated:
• Print a Configuration page or Test Page from the Control Panel or Command
WorkStation.
• Select a calibration set in Calibrator (available from ColorWise Pro Tools)—the last
calibration and the user who performed it are displayed.
Using Calibrator
ColorWise Pro Tools Calibrator allows you to calibrate the GA-1121 using the
measurement method of your choice.
Changing the calibration has the potential to affect all jobs for all users, so consider
limiting the number of people authorized to perform calibration. Set an Administrator
password to control access to calibration (see the Configuration Guide).
NOTE: Multiple users can be connected to one GA-1121 with ColorWise Pro Tools,
but only one user at a time can use Calibrator. An error message appears if you try to
calibrate when another user is using ColorWise Pro Tools to calibrate.

of the new measurements with any profile associated with the currently selected
calibration set. You can also create a custom comparison page and save it as a
PostScript or Encapsulated PostScript (EPS) file called CALIB.PS. Next, print the file
to the Hold queue of the GA-1121 from your application, or download it to the Hold
queue with Fiery Downloader. An additional way to create the CALIB.PS file is to
rename any job in the Hold queue using Command WorkStation (see the Job
Management Guide).
With the View Measurements option, you can view the current set of measurements as
a table or graph that shows both the measurements and the target curves.

Using AutoCal and ColorCal
AutoCal and ColorCal allow you to calibrate the GA-1121 without the use of an
additional spectrophotometer or densitometer. Instead, these methods use the
copier/printer’s built-in scanner to measure toner density values. Using either AutoCal
or ColorCal provides an equally accurate calibration of the GA-1121.
AutoCal and ColorCal have the following differences:
• Scanner calibration—ColorCal lets you calibrate the scanner (copier feeder) using
the Kodak Color and Gray Scale strips. AutoCal lets you calibrate the copier using
the Kodak Gray Scale strip; scanner calibration is not available.
• Measurement page—For ColorCal, square black-and-white and color patches are
randomly printed on the ColorCal Measurement Page. This allows ColorCal to be
less influenced by copier conditions, providing greater accuracy in color
reproduction and calibration.
AutoCal is provided for compatibility with earlier GA-1121 servers. You can perform
AutoCal or ColorCal calibration from either ColorWise Pro Tools or the GA-1121
Control Panel. For troubleshooting during the AutoCal procedure, see the Job
Management Guide.
NOTE: To calibrate using AutoCal or ColorCal, you will need the Kodak Gray Scale
strip included in the customer media pack that came with your GA-1121. You also
need the Kodak Gray Scale strip and Kodak Color Control Patches strip to calibrate
the scanner of the copier/printer for ColorCal.

Profile Manager
Profile Manager allows you to manage and edit ICC profiles. In the case of the
GA-1121, these profiles are divided into RGB Source, Simulation, and Output
profiles:
profiles are used to define the source color space for RGB colors processed by the
GA-1121.
NOTE: If you use Photoshop 5.x, 6.x, or 7.x, you can upload the profile for your
selected working space to the GA-1121 and choose that as your RGB Source Profile.
For more information, see the Fiery Color Reference.
• Simulation contains printer profiles used to simulate another device on the
GA-1121.
• Output contains copier/printer profiles that describe the copier/printer. For more
information on output profiles, see page 1-15.
NOTE: Changing the GA-1121 default profiles affects all jobs for all users. Consider
limiting the number of people authorized to use ColorWise Pro Tools by setting an
Administrator password.

In addition, one or more output profiles are provided with the GA-1121.For
information about output profiles, see page 1-15.
NOTE: When you use Profile Manager from some Windows NT computers, the default
color directory may not be created automatically when ColorWise Pro Tools are
installed. Create the color folder in the appropriate directory (for example,
C:\WinNT\system32\Color) and Profile Manager will be able to download and
upload from the default location as expected.
Setting the default profiles
The default profiles are applied to all print jobs sent to the GA-1121, unless you
override them using print options. Therefore, the defaults should be the most
commonly used profiles.
TO SPECIFY A DEFAULT PROFILE
1. Start ColorWise Pro Tools and click Profile Manager.

2. If the desired profile does not appear, click Browse to go to a different directory.
Browse to the directory containing the profile you want to download and click OK.
3. When the profile you want to download appears in the list in the main Profile Manager
window, select it.
If the profile is compatible with the GA-1121, a green arrow indicates that the profile
is available for downloading. Only output device profiles are downloadable to
Simulation and Output. Only input device profiles are downloadable to RGB Source.
NOTE: On Windows computers, the profiles must have an extension of .icc or .icm to
be listed. On Mac OS computers, the profiles must have a file type of “profile.”
All ICC profiles in the selected directory on your computer are displayed in the list in
the main Profile Manager window. However, because a profile is listed does not
necessarily mean it can be downloaded to the GA-1121.
Simulation profiles should be profiles only for those devices you want the GA-1121 to
match in terms of color output characteristics. Output profiles should be profiles only
for the copier/printer to which you print. Although you can download CMYK printer
profiles as Simulation or Output, consider how they will be used. If you want the
GA-1121 prints to look like another printer, download that profile as a Simulation. If
you have a custom profile of the copier/printer you print to, download that profile as
an Output profile.
4. Click the arrow to download the profile and click OK when the download is complete.
The new profile now appears in the list of profiles on the right side of the Profile
Manager main window.

For Mac OS computers, this profile must be associated with one of the predefined
names (Source-1 through Source-10 for RGB Source, Simulation-1 through
Simulation-10 for Simulation, or Output-1 through Output-10 for Output) or set as
the default before it can be used. For Windows computers, all profiles can appear in
the printer driver by their profile descriptions (see “Defining profiles” on page 3-7).
NOTE: When an output profile is downloaded, it inherits the calibration target of the
current default output profile.
Editing profiles
You can customize the profiles on the GA-1121 to meet your specific needs and the
characteristics of your copier/printer using Color Editor, either directly or through
Profile Manager. For more information on editing profiles, see “Color Editor” on
page 3-10.
Managing profiles
Profile Manager allows you to back up profiles to ensure that no custom profiles are
lost when the GA-1121 software is updated. You can also upload a copy of a built-in
GA-1121 profile to your workstation in order to use it with an ICC-aware application,
such as Photoshop. Profile Manager also allows you to delete unwanted profiles.
NOTE: You can back up and delete only those profiles that appear in the main Profile
Manager window without a Lock icon next to them. Locked profiles cannot be deleted,
but most can be backed up.
TO BACK UP PROFILES
1. Start ColorWise Pro Tools and click Profile Manager.
2. Select the profile on the GA-1121 to upload.
The arrow in the middle of the Profile Manager window turns green and points to the
left, indicating the profile is available for upload.
3. Click the green arrow, choose a name and location for the profile, and click Save.
The name will be the file name of the profile, but the profile description will be the
original description, or the one you entered in the Profile Settings dialog box.

TO DELETE PROFILES FROM THE GA-1121
1. Start ColorWise Pro Tools and click Profile Manager.
2. Select the profile you want to delete and click Delete.
A Warning dialog box asks you to confirm the deletion.
NOTE: You cannot delete preset profiles, profiles that are currently set as default, or
profiles that are linked to any of the predefined custom names, for example
Simulation-1.
3. Click Yes to delete the profile.
4. To delete a profile currently set as the default or associated with a custom name, click
Profile Settings and clear the default option.
Defining profiles
For Mac OS computers, before you apply any downloaded or edited profile to a print
job, that profile must be linked to one of the predefined custom names, or you can set
the profile as the default for all print jobs (see “Setting the default profiles” on
page 3-3). Ten names are available for custom profiles—Source-1 through Source-10
for RGB Source, Simulation-1 through Simulation-10 for Simulation, or Output-1
through Output-10 for Output.
For Windows computers, all profiles appear by their actual names in the printer driver.
These fixed names are used in the printer driver, so you can select profiles per job even
if your driver does not have the capability to obtain an updated list from the GA-1121.
NOTE: A custom simulation profile is used to illustrate this procedure. The same steps
apply for defining output profiles.

If you do not define a custom simulation profile, your job will print with CMYK
Simulation Profile set to None. If you do not define a custom RGB Source or Output
profile, the default profile is used.
Considerations for defining Output Profiles
The procedures for defining Output Profiles is similar to the preceding example for
defining Simulations profiles. However, note these differences:
For output profiles, the predefined custom names are Output-1 through Output-10.
When you choose Profile Settings for an output profile, the Use Calibration Set
options also appear. You must calibrate the GA-1121 with this calibration set before
this option has any effect. If you have never measured for this calibration set, default
measurements are used. For more information about calibration sets, see page 2-2.
Color Editor
Color Editor allows you to customize simulation and output profiles. Access Color
Editor directly by clicking its icon in the ColorWise Pro Tools main window, or
indirectly, through the Profile Manager.
Editing profiles
Color Editor allows you to create custom profiles by editing existing simulation or
output profiles and saving the changes as a new profile. Use Color Editor to fine-tune a
profile on your GA-1121 to meet your exact specifications. For example, you can
create a custom profile for printing to a specific media type.
NOTE: You cannot edit source profiles; only simulation and output profiles can be
customized.
Color Editor has two Edit Modes for editing output profiles:
• Custom—Edit output profiles and save customized versions of them.
• % Density—View the calibration target, which is one component of the output
profile. You cannot make changes to the calibration target in this window, but you
can import a new target (see page 2-2).

Color Editor also has several Edit Modes for editing simulations:
• Master—Create a custom master simulation that affects all print jobs to which it is
applied, unless a linked simulation exists for the selected combination of simulation
profile, simulation method, and output profile.
• Quick, Full (Source GCR), or Full (Output GCR)—Create custom linked simulations.
Linked simulations affect the print job only if the corresponding simulation profile,
simulation method, and output profile are selected. If you choose an output profile
and simulation method for which you have created a custom linked simulation, that
simulation is applied automatically to the job. If you choose a simulation method or
output profile for which there is no custom linked simulation, the master simulation
is automatically applied. For detailed information about simulation methods, see
page 1-13.
NOTE: If you made edits to a master simulation after you created a linked simulation,
the edits are not applied to the linked simulation.
TO EDIT A SIMULATION PROFILE IN MASTER MODE OR AN
OUTPUT PROFILE IN CUSTOM MODE
1. Start ColorWise Pro Tools and click Color Editor.
2. Choose Simulation or Output from the View menu.
Simulation lists the simulation profiles resident on the GA-1121, and Output lists the

5. Select the colors you want to edit by turning colors off and on.
The Eye icon to the left of each color indicates whether that color is visible on the
graph and will be affected by changes to the curves, brightness, and dot gain controls.
You can view and edit all four colors (cyan, magenta, yellow, and black) at once, or in
any combination. Working with only one or two colors at a time allows you to
fine-tune your adjustments. To turn off a color, click its Eye icon. In the following
example, cyan and magenta are visible and can be edited.
6. To adjust the dot gain value for simulating press output, click Dot Gain.
Choose either the North American or European standard. Use the sliders to adjust to
the desired Dot Gain:
• The range of values for North American at 50% input are from 0% to 50% gain on
output.
• The range of values for European at 40% input are from 0% to 59% gain on output;
the range of values for European at 80% input are from 0% to 20% gain on output.

9. For an output profile, set maximum densities of the C, M, Y, and K channels.
Enter the maximum densities, called D-Max values, of individual colors for profiles
that support density settings. D-Max settings are not available when you edit
Simulation profiles in Master mode.
10. When you are finished, click Save and enter a name for the new profile.
The new custom profile is saved to the GA-1121 with the new name. If you edit one of
the press standard targets (for example, SWOP-Coated, DIC, or Euroscale), consider
including the original name as part of the new target name (for example, DIC-new) to
help you remember the source of the new target.
NOTE: Preset default profiles are locked and must be saved with a new name.
For Mac OS computers, custom profiles must be linked to one of the 10 predefined
custom profile names (Simulation-1 through Simulation-10 for Simulation, or
Output-1 through Output-10 for Output) to be accessible from the printer driver.
Create as many custom profiles as you want, but a maximum of 10 are available from
the printer driver at any one time. For information on linking custom profiles to the
predefined custom profile names, see “Defining profiles” on page 3-7. If you are using
the printer driver for Windows computers, custom profiles will appear in the driver
window without being associated with a predefined profile name.
If you set a custom profile as the default, you can access it from the printer driver
without linking it to one of the predefined custom names. Select Printer’s default from
the printer driver.

For this new simulation to be automatically applied to a print job, the CMYK
Simulation, Simulation Method, and Output Profile settings must be the same as those
used when you edited the profile. If the Simulation Method is different or a different
output profile is selected, the Master simulation is applied.
NOTE: A CMYK Simulation Profile can have a custom Master and one or more custom
links—up to three links (Quick mode and the two Full modes) for each output profile
on the system. For the CMYK Simulation Profile option in the printer driver, note that
if you select a custom profile for which the output ink percentage is greater than 0 and
the input ink percentage is 0, the Use Master print option will have no effect.
Undoing CMYK simulation edits
You can undo the changes you made to CMYK simulations (master and linked) in the
following ways:
• If you have not yet saved your edits, click Done on the Color Editor menu bar and

You can also search for a particular color in the Spot-On list.
Color groups in the Spot-On window appear in order of their priority. Highest priority
is given to color groups at the top of the list. For instance, if two colors from two
different color groups have the same name, the GA-1121 uses the color from the
higher group and disregards the other color. By managing the priority of colors in this
way, you can maintain several CMYK variants for the same spot color.

Editing color values
The Spot-On Color Search targets the exact CMYK toner equivalents required to
simulate a desired spot color on the copier/printer. If an existing spot color is not
printing as desired, you can modify the color values as needed to achieve your intended
result. Beginning with an approximate color, you can adjust the hue, saturation, and
lightness of the color until you achieve a desirable match.
TO TARGET A COLOR USING SPOT-ON COLOR SEARCH
1. Select a color icon from a color group and choose Color Search from the Edit menu.

Center Patch
2. To update the center patch to a neighboring color that more closely matches the
target, click the corresponding neighbor patch.
Neighboring patches represent variations from the center patch and can be selected if
they offer a closer match to the desired color. Clicking one of these patches updates the
center patch to the new color and provides a new selection of neighboring colors.
These patches are either lightness or saturation neighbors, depending on the option
you choose in the following step.
NOTE: When you select certain colors, an exclamation point icon may appear in the
the edge of the copier/printer’s printable gamut and may not be reproducible. In such
cases, we recommend that you use an approximate target that lies within the gamut,
rather than the out-of-gamut color.
You can also click the center patch to enter CMYK values directly. For more
information, see the procedure on page 3-28.
3. Use the following techniques to control how neighboring color patches are generated:
Select either Lightness or Saturation in the Color Directions Legend.
Lightness generates neighbor patches based on darker to lighter shades of the original
color. This variation is displayed from left to right, with the original color remaining in
the center of the middle group.

3-27 Using Spot-On
3
Saturation generates neighbor patches based on less saturated to more saturated
variations of the original color. This variation is displayed from left to right, with the
original color remaining in the center of the middle group.
Choose a setting from the Color Spacing menu to control the closeness of the neighbor
patches.
A higher setting generates neighbor patches that differ more noticeably from the center
color. As you get closer to your target color, reduce the color spacing to a smaller value.
Select Monitor Compensation to simulate how all the on-screen color patches will
appear when printed on paper.
This simulation depends on the monitor profile that has been configured for the
display. To specify the monitor profile, choose Preferences from the Edit menu in the
Spot-On main menu.
If you use the monitor that is part of the option, select the monitor profile that is
installed with the option. If you use another monitor, select a profile customized to
describe the characteristics of that monitor.
4. Continue adjusting the color patch controls and clicking neighbor patches until the
desired color appears in the center patch. Click Print Pattern.
5. Choose Output Style, Paper Size, and Paper Tray options.
For Output Style, choose between Color Search Pattern and Color Neighbor Pattern.
Color Search Pattern prints patches with the same pattern as displayed in the Color
Search window. Color Neighbor Pattern prints patches in a three column by eight row
format.
For Paper Size, choose the size of the paper you want to use for printing the patches.
For Paper Tray, specify the input tray for the paper you want to use.

6. Click OK to print the patches.
The Print Pattern test page prints the following information:
• Center patch color CMYK value
• Color spacing
• Lightness or Saturation neighbors selected
• Output profile selected
The goal of the Spot-On Color Search is to find the color values that make a printed
color patch match a target, not the screen simulation of it. Printing a Print Pattern of
the neighbor color patches allows you to compare the printed patches to the color
target. Once you compare the printed patches and find the one that matches most
closely, you can then select the corresponding patch on the screen.
7. When you have selected the desired target color in the Spot-On Color Search window,
click OK.
The edited color appears in the color list of the main Spot-On window.
TO TARGET A COLOR USING EXACT CMYK VALUES
1. Click the center patch in the Spot-On Color Search window.
The Set Center Patch Color dialog box appears.
2. Select how you want to enter the CMYK values.
The Percentages option allows you to enter color values between 0 and 100%, in
increments of 0.5. Values out of this range are rounded to the nearest whole or half
percentage.

The Device Codes option allows you to enter color values between 0 and 255. This
option reflects the full range of color values that the GA-1121 can actually reproduce,
and provides finer gradations of color than are possible with Percentages.
3. Enter the C, M, Y, and K values of your specific color in the appropriate fields.
Use the Tab key to move from field to field. As you enter each new value, the preview
patch updates to reflect the old and new colors.
4. Click OK.
The new color appears as the center patch in the Spot-On Color Search window.
Using a measurement instrument to target colors
If you have the EFI Densitometer ED-100 or EFI Spectrometer ES-1000, you can
import measured color values directly into Spot-On. This feature allows you to target
matches based on the actual colors of immediate objects, such as the red of a printed
logo or the yellow of a packaging envelope.
For best results, download and save any measurement data you have gathered with the
ED-100 or ES-1000 in its offline state. Spot-On automatically clears stored data when
it establishes a connection with the instrument. For information on downloading
stored data from the ED-100 or ES-1000, see the documentation included with the
instrument.

B-1 Importing density measurements

This appendix describes Simple ASCII File Format, which can be used to import
density measurements from measurement devices. To use your own measurement data
from an alternate measurement instrument, record your individual readings in a text
file and structure it as follows.
Appendix B:
Importing
density
measurements
Simple ASCII Import File Format (SAIFF)
This format describes Status T measurement data for import into the ColorWise Pro
Tools Calibrator. The three possible file formats are:
• 1D Status T density for EFI 34 patch page
• 1D Status T density for EFI 21 patch page
• 1D Status T density for other pages (maximum of 256 patches per ink)
The file format is ASCII and has no tabs. A single space or multiple spaces are used as
delimiters. Blank lines are not allowed. Each line in the file represents four patches (C,
M, Y, K) of a specific ink value. Comments may be on any line in the file, and these
lines start with a pound sign (#) followed by a space. A line with a pound sign followed
by any character other than a space has been reserved. Comments must be on an entire
line by themselves.
Each line of data contains five values. The first number is the sequential patch number
(for EFI 34 and EFI 21 pages) or the ink value percentage (for other pages). The four
values that follow are the density values of C, M, Y, and K of the corresponding patch.
Lines are ordered either by increasing sequential patch numbers, or by increasing the
ink percentage.
For Windows computers, the file extension must be .cm1. For Mac OS computers, the
file type must be ‘TEXT’.
Measurement data in EFI 34 and EFI 21 are paper-relative. For other pages, if the first
line corresponds to zero ink value, the Calibrator assumes that the measurement data is
absolute and adjusts it to become paper-relative by subtracting the density values of the
first line from the remaining patches.
