Abstract

A method for image inspection and color guidance for printing products of a printing press, in which in on-line operation, actual image data of the printed images of the printed products are obtained and compared with nominal image data for the purpose of locating image defects, which comprises the steps of checking, upon the appearance of a defect, before any change in the ink feed is made, as to whether on the basis of the type of defect, some other cause than the color guidance for the deviation is possible.
