摘要： A method of printing an image by a printer having an asymmetric printer resolution includes multi-level halftoning the image by assigning a level out of a number of levels to each pixel of the image. The method further includes determining the number of levels on the basis of the asymmetric printer resolution, selecting for each level a collection of at least one binary pattern, each binary pattern consisting of a plurality of sub-pixels the number of which is determined by the number of levels, selecting for each pixel of the halftoned image a binary pattern from the collection selected for the level assigned to the pixel, transforming each pixel of the halftoned image into the selected binary pattern, and printing the binary patterns of the transformed pixels using the asymmetric printer resolution. A printer is configured to perform the method.
