Abstract
A method of printing using variable pixel replication factors involves generating from an input image a reference image and a plurality of half-tone source images generated at different resolutions of the input image and with post-halftoning pixel replication factors applied such that the half-tone source images are all the same size. A pixel-replication factor selector function is applied to each reference pixel of the reference image to determine a respective source image for that reference pixel. Thus, different reference pixels correspond to different pixel replication factors. A print-state image is assembled by applying to each print-state image pixel the print state of the corresponding source pixel in the corresponding source image. The print-state image is then printed to a print medium.
