_icm Inline Colour Measurement

A good grip on colour

Providing a consistent colour scheme at all printing units throughout the entire printing job is still one of the most difficult tasks in the printing technology. This applies particularly to web-fed printing with high print speeds and the difficulties of a visual inspection.

By using the _icm module for the inline colour measurement of colour deviations, the operator is able to define measuring points simply at any desired position in the image – even in the colour bars and colour gradations.

The measuring results are visualised and logged for the operator as individual measurements and trend analyses.
The _icm module completes the automatic quality inspection.

Based on the CIE-Lab colour space icm

distance to reference colour
» delta E / delta E cmc
» delta L
» delta a / delta b
» delta C / delta H

Additional functions:

» tolerances selectable for each measuring point
» display of tolerance deviations in two alarm levels
» saving the job data for repeat jobs
» measuring points directly in the design
» current measurement and colour gradation diagrams
» logging of the measuring results (protocol)
