TECHNICAL TUTORIAL: Inkzone

The InkZone concept for presetting the ink keys on offset printing presses is making life easier for printers: they are saving money and gaining time; at the same time, they are achieving considerable increases in quality and productivity.

InkZone smoothens the way into a future with JDF files supplied from the workflow or bitmap or CIP3 data that has been converted by DI-Plot into the job definition format. This is  converted by InkZone into the required preset control commands for the specific machine.

In many printing houses, preset values for ink zones are still generated using plate scanners. Apart from the laborious handling of the printing plates, the scanning of plates will also result in a relatively imprecise ink profile due to weak contrast between the aluminium and ink-bearing layer, which costs time and paper. Through the online transfer of bitmap files, on the one hand a work-intensive detour via the plate scanner is eliminated, while on the other, InkZone will always refer back to first-generation data. That means, shorter set-up times and minimum start-up waste. In view of shrinking print runs and frequent job changes, this means a significant increase in productivity.

InkZone extends DI-Plot, the RIP-independent form proof solution, by a new component and brings manufacture-independent workflow all the way to the press. Now, bitmap data calculated by DI-Plot and used for the formproof can be simultaneously used for presetting the ink zones on the press. InkZone can be used with all popular press types and can be upgraded with InkZone simply and economically.
