<p>An image dithering system for producing dithered image values in response to continuous tone image values and in response to a rectangular dither matrix generated based on a dither matrix designed for a hexagonal grid. Such a rectangular dither matrix is more immune to asymmetrical grid patterns, whose aspect ratios differ from one, than are dither matrices based on other grid patterns, most notably for square or rectangular grid patterns.</p> |
