Abstract
A system and method is disclosed for print production sheet identification. The method discloses: receiving a set of calibration sheets; collecting an array of pixel samples from at least one of the calibration sheets according to a set of pixel sampling rules to generate at least one reference sample array; capturing an image of a set of physical sheets generated from the set of calibration sheets; collecting an array of pixel samples from at least one of the imaged physical sheets according to the set of pixel sampling rules to generate at least one post-processing sample array; and comparing the post-processing sample array to the reference sample array to determine if the two arrays have less than or equal to a predetermined number of differences. The system discloses: a sampling module, operated by a processor, a scanner, and a comparison module, operated by a processor.
