Abstract
A method of operating a digital printer for producing a printed image on a print medium is described. The method is intended for use with a printer which includes at least one memory for holding an overlay pattern bit map which defines an overlay pattern at least portions of which are utilized in printing the printed image onto the print medium, and an image processor for processing 3image data used to produce the printed image. The method includes defining at least one fill area to be printed with at least a portion of the overlay pattern; reading at least a portion of the overlay pattern bit map from said memory; providing at least one boundary point which in part defines a fill area subset which serves to fill a portion of the fill area and define a portion of the printed image appearing therewithin; applying at least a portion of the overlay pattern bit map read from memory to the fill area subset; writing the fill area subset to an output buffer which stores data defining at least a portion of the printed image; and servicing the print mechanism at variable or constant paper slew rate. According to a preferred embodiment, a 3-parameter model is used to determine the incremental image processing cost of pattern processing.
