Color job output matching for a printing system
Abstract:
A printing system is provided for color job matching of the output from a plurality of image marking engines. The system includes a first test image printed by a first image marking engine on a media document. The first test image having a data glyph and a plurality of reference patches. The system further includes a second test image printed by a second image marking engine on the media document. The second test image having a data glyph and a plurality of reference patches. The first and second test images are printed on the same side of the media document. A scanner is provided for scanning the media document. The scanned first and second test images provide calibration data for matching color correction tables of the first image marking engine and the second image marking engine, wherein the data glyph and the reference patches of the scanned image data 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 the first image marking engine or the second image marking engine.
