Patent ID: 8760670

Claim:
A method, executed by a computer, for print production sheet identification, comprising: 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; 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; in response to determining that the two arrays have less than or equal to the redetermined number of differences, identifying the set of physical sheets as the set of calibration sheets; and in response to determining that the two arrays do not have less than or equal to the redetermined number of differences, identifying the set of physical sheets as not the set of calibration sheets.
