INSPECTION APPARATUS, IMAGE FORMING APPARATUS, INSPECTION METHOD, AND COMPUTER-READABLE STORAGE MEDIUM

摘要

The present invention provides an inspection apparatus including a pause control unit which, when a defect is detected in a page of a printed product while the printed product is continuously printed, causes printing to pause, a predictor unit which, when printing is paused, predicts whether a defect will be detected again in restarting printing by using a master image of a not-yet-printed page, a master image of the defect-detected page, and a predetermined defect prediction criterion, and a resumption control unit which permits to restart printing the defect-detected page and pages following the defect-detected page if the predictor unit predicts that a defect will not be detected again in restarting printing, and prohibits from restarting printing if the predictor unit predicts that a defect will be detected again.

主权项

1. An inspection apparatus for inspecting a printed product, the inspection apparatus comprising:
a generating unit configured to generate master images corresponding to the printed product containing multiple pages before the printed product is printed; an inspection unit configured to inspect the printed product for a defect by comparing scanned images obtained by scanning the printed product with the master images; a pause control unit configured to, when the inspection unit detects a defect in a page of the printed product while the printed product is continuously printed, cause printing to pause; a predictor unit configured to, when the pause control unit causes printing to pause, predict whether or not a defect will be detected again in restarting printing by using one master image of the master images generated by the generating unit, the one master image being of a not-yet-printed page, a master image of the page where the defect is detected by the inspection unit, and a predetermined defect prediction criterion; and a resumption control unit configured to permit to restart printing the page where the defect is detected by the inspection unit and pages following the defect-detected page if the predictor unit predicts that a defect will not be detected again in restarting printing, and prohibit from restarting printing the page where the defect is detected by the inspection unit and the pages following the defect-detected page if the predictor unit predicts that a defect will be detected again in restarting printing.
