METHOD FOR INSPECTING A PRINT IMAGE IN A PRINTING PROCESS
A method for inspecting a print image in a digital printing process, with image data from images to be printed being available in a pre-printing stage in the form of a digital proof, includes the steps of generating a reference image representing the desired printing result; recording digital live images of printed images; comparing the live images with the reference image; before the print process, searching the digital proof for distinct points in the image to be printed, selecting such points as reference points and determining coordinates thereof, and rendering and saving the digital proof as a reference image; and after printing has started, for each live image, finding the reference points in the live image, calculating a coordinate transformation which converts the reference points of the live image and reference image into one another and comparing the live image with the reference image after applying the coordinate transformation.
