Abstract
A method for image inspection of printed products in a printing material processing machine includes using an image sensor to capture and digitize printed products during image inspection by an image capture system, using a computer to carry out a comparison of captured digital printed images with a digital reference image, examining a result of the comparison for image regions with blurry regions in the captured digital printed image, calculating suitable smoothing factors for the blurry image regions, and then carry out smoothing of the digital reference image with the calculated, suitable smoothing factors for the blurry image regions, causing the digital reference image to have a blurriness comparable to the captured digital printed image in the image regions. Printed products detected as faulty are removed upon an occurrence of deviations of the captured digital printed image from the digital reference image.
