Abstract
A digital image inspection method checks printing material processing machine products by recording digital printed partial images using recording devices and combining partial images in an image processing computer forming a digital overall image causing abutment edges at an overlap. The computer inspects the digital overall image and transmits a result to a machine control computer. The computer creates a new image, only containing detected edges, using edge detection methods after combining partial images forming a digital overall image. The computer uses known positions of abutment edges of recording devices to create a further new image only containing regions with abutment edges of recording devices. The computer overlays the new images, providing a resultant image containing only edges along abutment edges of recording devices. The computer applies the resultant image to the digital overall image, defining masking zones in the resultant digital overall image not being checked by image inspection.
