Abstract:
A method of designing color dither matrices comprising:a) generating a design tile map; b) receiving at least two color tiles; wherein each color tile is identified by a color tile number (CTN); wherein each color tile includes a plurality of pixels that are divided into a plurality of concentration levels that are specified by a color tile concentration level (CTCL); c) setting the CTCL of each color tile to a first CTCL value; d) initializing all the color tiles; e) generating a mosaic color tile based on the design tile map, the mosaic color tile having a plurality of color tile locations; wherein the design tile map specifies a particular color tile for each color tile location; and f) jointly designing at least two sets of color tiles without using a training process; wherein the two sets of color tiles together seamlessly.
