COLOR DIGITAL PRESSES--Decisions, Decisions . . .

The 74 Karat can print up to 10,000 sph, in formats up to 201⁄2x29˝, on a wide range of papers. Bartram states that it takes six minutes to image a full set of 2,540 dpi Presstek plates.

It is the only press to offer the Gravuflow inking system, which is designed to minimize operator intervention and place the responsibility for color management with the prepress department. Sensors in the ink chamber detect ink consumption and initiate replenishment, when necessary. A precision-engraved roller sits under the ink chamber, right above the form. Doctor blades maintain a measured volume of ink in the engravings on the Gravuflow roller, so that a consistent amount is transferred to recharge the form roller.
