Patent ID: 8317291

Claim:
A method for generating test strip images in a printing system comprising: illuminating blank media as the media travels over a rotating member; generating electrical signals from light reflected by the blank media as the blank media travels over sectors of the rotating member; converting the electrical signals to image data of the blank media as the blank media travels over the sectors of the rotating member; computing a mean average image for each sector of the rotating member from the image data for the blank media that traveled over each sector of the rotating member; storing each mean average image in a memory in association with a sector identifier; printing a test strip on media; illuminating the media as the media on which the test strip is printed travels over the rotating member; generating electrical signals corresponding to light reflected by the media as the media on which the test strip is printed travels over the rotating member; converting the electrical signals to image data of the media on which the test strip is printed; modifying the image data of the media on which the test strip is printed with the image data of the blank media; and storing the modified image data in the memory.
