Designed specifically for proofing flexographic and gravure print jobs that require white, the Stylus Pro WT7900 incorporates high-resolution ink jet technology, including breakthrough UltraChrome HDR white ink. The proprietary white ink introduces Organic Hollow Resin Particle Technology, which forces light to randomly scatter, producing the illusion of seeing the color white. This innovative ink yields an amazing white density, ability for custom white color toning and provides professional short-term color stability for mission-critical color proofing on a range of substrates including ink jet coated transparent and metallic films up to 24 inches wide when printed on the Stylus Pro WT7900.
