Isra Vision launches ColorStar

Isra Vision has launched ColorStar, a new module for its PrintStar 100 percent print inspection system, claimed to reduce make-ready times by 60 percent and decrease material consumption.

The new module provides the PrintStar inspection system with absolute color measurement data. This feature enables continuous monitoring of the color accuracy of printed products on printing machines, without interrupting production.

Color line scan cameras are combined with a spectrophotometer to enable continuous measurement and monitoring of absolute color values (L*a*b*) and color density. These measurements can be performed and repeated at any point in the process. As soon as printing commences, the measured color values are compared to the target specifications.

The operator can adjust the color without having to stop the printing machine. Isra claims that taking real-time measurements can reduce make-ready times by up to 60 percent and significantly lower material consumption. The system guarantees color consistency throughout the entire print batch eliminating the need for manual measurements with any deviations exceeding an adjustable limit value triggering an alarm.

The ColorStar is suitable for all substrates and operates at any printing speed. Measurement positions are tracked automatically and continuously for all materials, including thin and stretchable ones, without any additional equipment.
