An optical checking method for evaluating quality in print processing and a device for performing the method, wherein at least one flat printed product (101, 102), a product group, or a product flow fed along a conveyor section have at least one beam profile S and at least one mirrored beam profile SP. Line profiles and mirrored line profiles are generated on different surfaces (105, 106) of the printed products (101, 102), the product group, or the product flow by means of the beam profile and mirrored beam profile, said line profiles being able to be simultaneously captured in turn directly and in a mirror (15) by a camera (20). |
