Abstract: Methods and systems for printing an image on a receiver medium are provided. In accordance with the method, digital image data representing an image to be printed is received and, a print engine is used to print an image on the receiver medium based upon the digital image data and initial printing settings. A press sheet image is captured of the image printed on the receiver medium and, the press sheet image is automatically compared to the digital image data to detect differences. Selected types of differences can be identified or can be addressed by adapting the press sheet image or adjusting digital image data prior to comparison.

Abstract: One general aspect of the invention provides for creating half-tone ink-jet proofs on print-enhanced sheets based on an effective image cell pitch that substantially matches a cell pitch used to create press plates. Print process variables can be adjusted for the ink-jet proofing printer based on received color matching information. These adjustments can define preprint ink mixing ratios that allow at least some image cells to be printed with ink mixtures. Or they can define sub-area printing values that allow at least some dots to be printed with areas of different inks.
