Epson America has introduced a contract-quality proofing system designed to improve how package designers and flexo and gravure printers produce packaging mock-ups and proofs. The Epson Stylus Pro WT7900 utilizes an aqueous-based white ink printing technology and Epson’s latest achievements in high-resolution inkjet technology. Together, these advancements produce a new way of printing with the color white on a broad range of substrates, including inkjet coated transparent and metallic films, according to Epson.

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

Designed for proofing flexographic and gravure print jobs that require the color white, the WT7900 utilizes Epson UltraChrome HDR White Ink, which features a technology that forces light to scatter randomly, producing the illusion of seeing the color white, says Radogna.

“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,” he says. “It also provides professional short-term color stability for mission-critical color proofing on a range of new substrates, including inkjet 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.”

In addition, Epson worked closely with CGS, EFI, GMG, EskoArtwork, and Kodak to ensure that those companies’ RIP and workflow softwares take advantage of the WT7900 technology.

The Epson Stylus Pro WT7900 will be available through authorized Epson resellers in February 2010 for about $8,500.
