Abstract
A method and a device for the quality inspection and testing of a flat print product. A print product, including at least one structural element, is initially deposited on a support element and illuminated by at least one light source. At least one image of the illuminated print product is generated using at least one image recording unit. An image is also generated of at least one structural element on the support element and a geometric object of the support element is determined from the at least one structural element of the support element. Actual values for the at least one geometric object of the support element are compared to predetermined desired values for this geometric object and the result of the comparison is used for controlling the further processing of the print product.
