Variable-Sized Droplet Technology
By controlling the electric pulse applied to the print
head’s piezo element, the Epson Stylus
™
Pro 7900/9900’s
MicroPiezo
™
print head
is capable of producing several
different sizes of ink droplets, depending on the image
type and media used. This new generation of MicroPiezo
print head improves the Variable-Sized Droplet function to
improve image quality while optimising print speed.
2880 x 1440 dpi resolution
The Epson Stylus Pro 7900 and 9900 offer industry-leading
output quality, with print resolutions of up to 2880 x 1440dpi.
This is achieved as the result of technologies that include
Variable-Sized Droplet Technology, which supports ink droplets
as small as 3.5pl, and Advanced Meniscus Control, which
enables the printer to
deliver sharp, accurately placed
spherical ink droplets with high levels of precision.
1440 x 1440 dpi mode
With the addition of a new
print resolution
– 1440 x 1440 dpi
– which can be used in conjunction with a third-party RIP, the
Epson Stylus Pro 7900 and 9900 deliver improved
quality and
dot sharpness
when generating 1 bit TIFF proofs.
High Speed Throughput
In contrast to their predecessors, the Epson Stylus Pro 7900
and 9900 are able to achieve print throughput at rates up to
more than
twice the speed
*.

• Smoother gradations:
In combination with the 10-colour ink system, the new LUT
technology delivers prints with noticeably
smoother colour
gradations and transitions.
Advanced LUT technology
Utilising a new and sophisticated colour
LUT (Look-Up Table) technology, the
Epson Stylus Pro 7900 and 9900 printers
achieve
high levels of optimisation
in
the key image quality areas of:
Poor
gradation
LUT with poor grain
characteristics
LUT with good
grain characteristics
LUT quality affects
the graininess of
skin tones.

• Grain reduction:
By improving the ink combination selection process, the new
LUT technology dramatically
reduces instances of image
grain
that tend to be prevalent in skin tones.
• Colour constancy:
With a colour constancy level of less than DeltaE 1.0, print
colours remain
visually consistent
when viewed under
different lights and lighting conditions.
