Epson Stylus®Pro WT 7900
REDEFINING THE FUTURE OF PRINTING

Seeing is Believing.
Over the past decade, Epson has innovated many aspects of commercial
proofing on paper. The result? More of today’s most successful
commercial printers rely on Epson for their proofing requirements than
any other. So, when we decided to develop an all-new contract-quality
proofing system for the unique requirements of flexographic and
gravure printing — we had a lot to live up to.
Introducing the Epson Stylus Pro WT7900 Printer.
Designed specifically for proofing flexographic and gravure print jobs that
require the color white, the Epson Stylus Pro WT7900 incorporates our
latest achievements in high-resolution ink jet technology — including our
breakthrough Epson UltraChrome®HDR White Ink.
Epson UltraChrome HDR White Ink introduces an all-new Organic Hollow
Resin Particle Technology, which forces light to randomly scatter, producing
the illusion of seeing the color white.
This innovative way to produce the color white yields an amazing white
ink density, enables custom white color toning, and provides professional
short-term color stability for mission-critical color proofing on a range of
new substrates including ink jet coated transparent and metallic films.
And unlike traditional white ink chemistry, Epson UltraChrome HDR White
Ink is a safer, water-based resin particle — void of any known carcinogens.
Capable of printing directly on both ink jet coated clear and metallic films,
in roll or cut sheet, up to 24 inches wide, the Epson Stylus Pro WT7900
can proof virtually any size print job thrown at it. Whether you’re creating
contract proofs of various packaging products requiring a clear or metallic
base, or producing color accurate packaging mock-ups or prototypes, the
Epson Stylus Pro WT7900 can easily proof your most difficult flexographic
and gravure print jobs.
With every new introduction of an Epson Stylus Pro printer, we continue
to innovate and refine the overall experience. With the introduction of our
latest Epson Stylus Pro WT7900 printer, Epson is once again redefining
what’s possible.
Welcome to a new generation of package proofing.

A Based upon print engine speed only. Total throughput times depend upon front-end RIP, file size, printer resolution,
ink coverage, networking, etc. Normal Mode based on 1440 x 720 dpi, when printing uni-directional on Epson
ClearProof Film.
B Cartridge yields vary considerably for reasons including images printed, print settings, temperature and humidity.
Yields may be lower when printing infrequently or predominantly with one ink color. A variable amount of ink
remains in the cartridge after the "replace cartridge" signal. Part of the ink from the first cartridges is used for
priming the printer. Ink is used for both printing and print head maintenance. All inks are used for both black and
color printing. For more information about cartridges see www.epson.com/cartridgeinfo
C White ink available in 150 ml or 350 ml only.
