Abstract:
A method of performing image quality analysis on an image output device having an output station that generates a hardcopy color image output from an input image, the method comprising:providing the image output device with at least one pre-printed hardcopy test pattern page having pre-printed marks that have been accurately measured in advance; generating a hardcopy image output from the image output device using a digital test pattern as an input image having marks that match those on the pre-printed hardcopy test pattern page, the hardcopy image being generated on one of the at least one pre-printed test pattern page; scanning the hardcopy image to form a digital raster image; and performing image quality analysis on the digital raster image, including determination of motion quality defects based on a comparison of the accurately measured pre-printed marks and the generated hardcopy image corresponding to the digital test pattern.
