Color measuring in a running offset press
Posted on Friday, 13 April 2018. Posted in Pressroom
InkZone Inline retrofits legacy as well as new sheetfed and web printing presses from various manufacturers with up-to-date inline color measurement technology. Combined with InkZone Loop, Digital Information’s proven automatic color control system, InkZone Inline enables older printing presses to achieve incredible gains in efficiency and print quality.
Traditionally, color measurement is performed offline at the offset press control console on the printed sheet. InkZone Inline, however, revolutionizes this process by integrating a color measurement system directly into the printing press. InkZone Inline constantly measures the color control strip as part of the running printing process. The corresponding values are displayed on a PC screen at the control desk via an informative and modern user interface. Based on the color values transmitted by InkZone Inline, InkZone Loop generates the optimal ink key settings for each ink zone and forwards them to the press control console. This state-of-the-art software informs the press operator, in real time, about current color stability without interrupting the printing process or needing to remove the sheet from the press.
The combination of InkZone ink-key presets and InkZone Inline color control is significant, bringing to nearly all sheetfed and web offset presses a remarkable reduction in paper waste and make-ready time. Simultaneously, InkZone Inline helps users to achieve perfect color consistency throughout the complete printing process.
InkZone is a modular product suite for retrofitting printing presses in operation by using advanced software and electronics. From ink key presetting (CIP3/4) to closed-loop color control—including color measurement and reporting technology—InkZone is claimed to be the industry’s most robust solution. InkZone is touchscreen based, communicates through XML/JDF, and runs on the current Microsoft Windows 10 operating system. InkZone is an open system with respect to the incoming prepress data (workflow), the measuring technology used (color measuring systems), and the offset press control console to be accessed (manufacturer of the press). There are nearly 4,000 offset printing presses retrofitted worldwide with the InkZone ink key preset and closed loop color control system.
InkZone’s distributor in India is Mumbai headquartered Advance Graphic Systems.
