摘要:
A process for altering the phase of banding artifacts of a printing device deals with the separation of low frequency luminance modulation into higher frequency colored modulation. The individual writing element that is used to print each line of an image is changed between the color channels. In the process, each channel is printed so that original image data are registered. Lower frequency neutral bands are then converted to higher frequency colored bands to reduce visibility of the artifacts.
