IMAGE FORMING APPARATUS TO VERIFY PRINTED IMAGE WITH MASTER IMAGE, IMAGE FORMING METHOD, AND STORAGE MEDIUM

An image printed on a recording sheet is read, and the read image is displayed on a display unit. An instruction to use the displayed image as a correct answer image is accepted, and an image generated from the image that the instruction to use is accepted is registered as the correct answer image. A printed image is verified by comparing the printed image with the registered correct answer image.

In a system that verifies a print detect in a printed sheet, inconsistency between the sheet side at the time of reference image registration and that at the time of verification processing is prevented from occurring without imposing complicated work on a user. An image on a sample sheet is registered in advance as a reference image in association with the sheet side and at the same time, the sheet discharge setting for the sample sheet is stored. Verification is performed by matching the sheet side associated with the reference image and the verification-target side of the printed sheet based on the sheet discharge setting stored as a sheet discharge setting in the print processing.
