Epson Introduces World’s First Aqueous-Based White Ink Proofing Technology

Epson America Inc. is announcing an all-new contract-quality proofing system that is designed to dramatically 
improve how package designers and flexographic and gravure printing professionals produce packaging mock-
ups and proofs. The Epson Stylus® Pro WT7900 takes advantage of the world’s first aqueous-based white ink 
printing technology and Epson’s latest achievements in high-resolution ink jet technology. Together, these 
advancements produce a new way of printing with the color white on a broad range of substrates including ink
 jet coated transparent and metallic films.

“For years, proofing products in this market have been very expensive for customers to purchase, maintain and 
operate,” said Mark Radogna, group product manager, Epson America. “When a white ink is required in the 
printing process, the Epson Stylus Pro WT7900 represents an exciting new way for proofing and prototyping both 
flexographic and gravure printing products.”

Designed specifically for proofing flexographic and gravure print jobs that require the color white, the Epson 
Stylus Pro WT7900 incorporates Epson’s latest achievements in high-resolution ink jet technology – including 
the 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 approach to producing the color white results in an extremely high white ink density, as well 
as the ability for custom white color toning. It also 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. Unlike 
traditional white ink chemistry, Epson UltraChrome HDR White Ink is a safer, water-based resin particle that is 
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 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 the most difficult flexographic and 
gravure print jobs.

In addition, Epson America worked closely with CGS, EFI, GMG, Esko Artwork, and Kodak to ensure their RIP 
and workflow software takes full advantage of the Epson Stylus Pro WT7900 technology.

The Epson Stylus Pro WT7900 will be available through authorized Epson resellers in February 2010 for an 
estimated price of $8,495.
