Abstract
A method for reducing banding artifacts in a printed image, including irregularly advancing a media that will be printed upon while employing an entire single mask for marking elements of a printhead; and calculating a difference between an irregular advance amount of the media versus a nominal advance amount of the media. Finally, the single mask is nonuniformly circulated by the difference calculated in order to compensate for the media being irregularly advanced.
