Abstract:
1. A system for color job matching in a printing system, comprising: a plurality of image marking engines; a first test image printed by a first image marking engine on a media document, said first test image having a data glyph and a plurality of reference patches; a second test image printed by a second image marking engine on said media document, said second test image having a data glyph and a plurality of reference patches; said first and said second test images printed on the same side of said media document; an image capture device for scanning said media document; said scanned first and second test images providing calibration data for matching color correction tables of said first image marking engine and said second image marking engine, wherein said data glyph and said reference patches of both said scanned first and second test images are compared with retrieved color correction tables for generating compensation values based on a difference between the scanned image set-up data and the color correction tables for at least a first subsequent image document on said first image marking engine or said second image marking engine; and, said set-up data is provided to said second image marking engine and a third image marking engine for matching said at least a first subsequent image document from said second image marking engine or said third image marking engine to said first test image document of said first image marking engine.
