Product Applications  
Description  
Kodak Imagelink DL 1000 Microfilm is designed  
to generate positive-appearing camera originals  
in fiche format from helium-neon lasers used  
in dry computer output microfilmers (COM)  
equipment such as the Kodak Komstar 100/200/  
300 Microimage Processors, Kodak Komstar  
Microimage Processor IV, Kodak Optistar  
Datawriter, Kodak Optistar V Processor,  
Kodak Komstar Processor V, and the Kodak  
Optistar Image Writer. This film can be handled  
in room light and the equipment it is used with  
does not require any special plumbing, venting,  
or dark rooms.  
Kodak Imagelink DL 1000 Microfilm 2482 is a  
rapid-access, thermally processed (dry) silver  
computer output microfilm. This film is designed  
to be exposed by a red (helium neon) laser.  
When developed, a positive appearing image is  
formed (dark characters on a light background).  
Kodak Imagelink DL 1000 Microfilm is an  
extremely fine-grain, high-contrast microfilm  
which offers the highest quality thermally  
processed microimage available. When  
DL 1000 is used with Kodak Premium 1000  
Thermal Print Film 1323, a very high-quality  
duplicate is achieved at optimum equipment  
throughput speeds.  
Imagelink DL 1000 Microfilm is primarily used to  
make masters for generating negative-appearing  
distribution copies (clear characters with dark  
background) on thermal print film. Positive- or  
negative-appearing copies can also be made on  
diazo or silver films, depending on customer  
preference. This film is not intended to be used  
as the primary “working” copy or for frequent use  
in reader printers.

Processing  
1. Produce a processed BLANK master fiche  
from the COM.  
Kodak Komstar Microimage Processors contain  
a heated metal drum which processes this film  
at 1.8 meters (6 feet) per minute. Starting point  
recommendations are 119 ± ½°C (246 ±1½°F)  
for five (5) seconds.  
2. Run an exposure series on the duplicator.  
• Request 11 copies in the semiautomatic or  
manual mode.  
• Set the exposure to 1.0.  
Duplicating Masters  
• Using the fresh Kodak Imagelink DL 1000  
fiche, start the copy cycle.  
Print film density aims recommended when  
printing from Kodak Imagelink DL 1000 Microfilm  
/ 2482 Microfilm masters onto Kodak Premium  
1000 Thermal Print Film 1323:  
• After each exposure, increase the exposure  
setting by 0.1.  
• There should be 11 fiche produced, with  
increasing background densities.

3. Using either a densitometer or the Kodak  
Thermal Print Density Comparator, select  
the fiche which has a density of 2.2 or  
close to, but not darker than, the “Upper  
Limit” patch on the Kodak Comparator.

This will become the background onto which  
the Komstar characters will be printed.  
See Kodak Publication D-49 for a description of  
Kodak Thermal Print Films.  
4. Produce an exposure series of Komstar  
data onto Kodak Imagelink DL 1000  
Microfilm such that it can be duplicated  
onto a fiche with the proper background  
density.  
Photographic Properties  
The following data are based on development in  
the Kodak Komstar Microimage Processor as  
recommended.  
Depending on the Komstar being used, this  
can be done in several ways.  
Exposure  
Kodak Optistar Image Writer  
Kodak Imagelink DL 1000 Microfilm / 2482 is  
exposed inside a computer output microfilmer  
using a helium-neon laser for characters and  
a tungsten light or helium-neon laser exposure  
for the forms slide.  
Note the current intensity settings.  
Run either a test job or the “Quality Monitor  
Test” from the Optistar Systems Console.  
Run the job several times and vary the  
intensity up or down (in increments of 10)  
each time.  
The optimum exposure intensity setting is  
determined by selecting from a complete  
intensity series produced according to  
procedures as indicated under “Exposure  
Optimization” below.  
Komstar 100/200/300 Microimage  
Processors, Komstar Microimage  
Processor IV, and Optistar Processor V  
Run either a test job or the “Quality Monitor  
Test” from the Optistar Systems Console.  
As the Komstar is running and starts a new  
column of data (determined by either counting  
frames or listening for the camera to change  
directions), increase the “Data Intensity”  
setting by one. This should produce a fiche  
with eight columns of data at eight different  
settings.  
Spectral Sensitivity  
Optimum sensitizing for helium-neon lasers  
(633 nm).  
Exposure Optimization  
To determine the proper COM and duplicator  
exposure settings, perform the following

with varying densities, the next step is to

For optimum storage life, store processed film  
in the dark at 70°F (21°C), 50% relative humidity  
or below, with other conditions as specified in

yielded the proper background density.

manufactured long enough to have experienced  
practical losses of the image. Extrapolation of  
high temperature keeping behavior to room  
temperature storage is always subject to some  
uncertainties. On the basis of work done at  
Eastman Kodak Company and by the ANSI/  
NAPM IT9-4 subcommittee, this film is estimated  
to maintain a usable image for at least 100 years  
when processed as recommended, and handled  
and stored as described in ANSI/NAPM IT9.11-  
1993. Storage at low temperature provides  
greater assurance of satisfactory image stability.

settings are determined, produce a master  
and duplicate fiche at those settings for  
future reference.  
After-Processing Information  
Handling  
As with all photographic products, exercise care  
to avoid scratches, abrasions, and fingerprints.  
It is recommended that camera originals be  
handled as little as possible and with lint-free  
nylon or cotton gloves.  
Processed Silver Microfilm—Specifications for  
Stability are listed in ANSI/NAPM IT9.19-1994.  
Print-up  
Because this is a heat-processed film with  
incorporated developers, extreme heat or an  
intense light source (i.e., readers and printers),  
can cause further development of the  
background area. Darkening of the background  
is called print-up. Print-up is cosmetic in nature  
and does not duplicate onto the second  
generation copy. Kodak Imagelink DL 1000  
Microfilm has properties which reduce print-up.  
NOTE: Refer to the latest revision of each  
ANSI or ISO Standard specified.  
Viewing and Printing  
Readers and viewers are a source of heat and  
light at the film plane and can possibly cause  
print-up. A reader whose gate temperature does  
not exceed 65°C (150°F)* will, even after the  
film has been viewed for several hours, maintain  
sharp and easily read images. Readers and  
viewers can be a source of scratches and  
abrasions. For these reasons, it is recommended  
that, whenever possible, only test fiche be used  
in a reader.  
*If the heat at the film plane is kept at 65°C (150°F) or lower  
when measured as specified in ANSI/NAPM IT9.19-1994,  
this print-up has no practical effect when viewing on a  
reader or in making duplicates on a printer.

NOTE: These photographic modulation-transfer values were determined by using a method similar to the one described in  
ANSI/NAPM PH2.39-1977(R1990) Photographic Modulation Transfer Function of Continuous-Tone Black-and-White  
Photographic Films, Method of Measuring. The film was exposed with the specified illuminant to spatially varying  
sinusoidal test patterns having an aerial image modulation of a nominal 35% at the image plane, with processing as  
indicated. In most cases, the photographic modulation-transfer values are influenced by development-adjacency  
effects and are not equivalent to the true optical modulation-transfer curve of the emulsion layer in the particular  
photographic product.
