ABSTRACT:
A system and methods for controlling print quality of a printed product of a printer, which may comprise an image acquisition unit for acquiring an electronic test image of printing on the printed product after printing by the printer, an image processor for comparing the test image of the printing with a prototype image of desired printing and determining a match between the printing on the test image and the printing on the prototype image, and means for generating an alarm representative of a print quality problem when the match between the printing on the test image and the printing on the prototype image does not satisfy a predetermined condition. The printed product is not required to include any reference marks.
