Digital halftoning techniques in printers which construct and utilize a mask in a dithering algorithm for a multitone printer are generalized by using a decision matrix in conjunction with a dithering matrix. For each pixel in the image, pixel grey value and a mask threshold value are obtained. Based on these values, a decision is made on the grey level to be printed at each pixel. For extensions to multiple component color images, each component is treated independently as if it were a grey scale image. The mask threshold values and sizes are likely to be tuned per component and therefore different.
