ABSTRACT:
The presence/absence of a printing failure on a printed product is accurately detected to prevent a defective product from mixing in printed products to be delivered to a customer. In order to achieve this object, a printing processing method according to this invention includes steps of inputting first image data, executing the printing process for a printing medium based on the first image data, reading the printing medium on which the first image data is printed to obtain second image data, specifying a determination area to be used to determine the presence/absence of a printing failure in the second image data based on a processing content after the printing process for the printing medium, and determining the presence/absence of the printing failure by comparing the first image data and the second image data corresponding to the determination area.
