Abstract:
A method has been developed for detecting defects in printed images. The method includes operating a printer to print a first printed image and a second image, where the second image is a duplicate of the first printed image. The method further includes generating image data that correspond to the first printed image and the second printed image, and identifying image defects using differences between the image data generated for the first image and the image data generated for the second image.
