摘要
An optical control method for use in print finishing, comprising the following steps: First, guiding a planar printed product (12, 13) along a conveying path past at least one optical sensor (14). Secondly, detecting an electronic image by the optical sensor (14), wherein the electronic image comprises at least one region of the printed product (12, 13). Thirdly, transferring the electronic image into a corrected image on the basis of corrective information, which converts a recording perspective of the at least one optical sensor (14) into a target perspective. Fourth, comparing the corrected image to a reference value or a reference image, and generating at least one signal (27) on the basis of a result of the comparison.
