Zusammenfassung:A method of controlling a printer to print of an image, the printer having a predetermined marking material printed dot size, the method comprising the steps of rasterizing the image and defining halftone super pixels within the image, calculating the average density of the marking material within the super pixels, selecting a pattern for marking the pixels within the super pixels as a function of the printed dot size so as to expand the distribution of printed densities printable by the printer.
