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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optical control method for detecting printed products during print finishing","description":"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).
