Rho 351R
Roll-to-roll UV-Inkjet Printer
The Rho 351R, a further development of
the Rho 350R, is a high-speed UV inkjet
printer for roll media, including: paper,
fabrics, vinyl and PVC films, up to a width
of 3500 mm (11.6 ft). The high print
quality, featuring fine text (as small as 4
point) and solid areas of colour with high
colour gamut and density, is achieved
using Durst Quadro Array print head
technology, innovative European mecha-
nical engineering and Durst’s proprietary
image software.
The high colour density of 2.25 D and the
ability to underprint white or use it as
a spot colour, enables both the printing
of coloured media and the production
of photo-quality backlits. The printing
of backlits is automated by the special
backlit function which applies double the
ink coverage in one printing operation.
The high productivity, up to 170 m2/hr on
mesh, for example, is further optimised
by the ability to print two 1600 mm
wide, different diameter rolls simultane-
ously, thus utilising the full width of the

which has been specially developed for
excellent flexibility, adhesion and colour
stability on flexible material. It is ideal for
printing on such material as soft banners
(fabrics) and backlit textiles, tents and
awnings, truck side curtains, POP/POS
signs, large format posters, building
wrapping, wall paper and PVC films for
backlighting, etc...
further by the stepless skip-white func-
tion in an XY direction.
The printing operation is enhanced by an
integrated manual cutting device and the
user friendly, industry standard LINUX
operating software. The built-in security
system allows for unattended printing
of large rolls and double sided printing is
made possible thanks to the laser driven
registration.

Rho-Roll Ink
Durst has developed for the Rho 351R
a specific, virtually odourless UV curing
acrylic ink which guarantees quick curing,
high adhesion, even on uncoated surfaces
and high flexibility. The high pigmenta-
tion of the ink provided high colour
density with wide colour gamut. The
output is immediately usable after
printing without any post-treatment.
The high flexibility of the ink ensures that
uncoated fabrics can be printed without
wicking and UV pre-coated fabrics show
no white breaks.

The Rho Roll Ink shows a far wider color
gamut than solvent inks especially on
polyester fabrics.
A special mechanical and electronic
device (optional) allows the simultaneous
