Method and system for inspecting variable-data printing

摘要

A method and system are presented for performing automatic inspection on the results of a print job that prints variable data. The print job is to generate multiple printed instances of a page containing variable graphics, and the inspection is to detect any printing defects on a printed instance of the page. In one embodiment, the method includes dividing the page into multiple non-overlapping areas using a division map prepared for the page. The non-overlapping areas include one or more static areas that include only static graphics and one or more areas that include variable graphics. The method includes capturing an image of the printed instance and, for each of the non-overlapping areas, retrieving an indication indicating whether or not the area includes any variable graphics, retrieving a rasterized image of an instant of the area from a memory location according to the indication, and comparing the rasterized image with the captured image of the area to detect any printing defects in the area of the printed instance.
