<P>PROBLEM TO BE SOLVED: To provide a process for coloring a substrate by using a liquid colorant, and to provide a corresponding product. <P>SOLUTION: The assignment of color is done on a pixel-by-pixel basis. Relatively large areas of the substrate may be given the appearance of being uniformly colored by successively replicating or tiling a group of individually colored pixels comprising a repeating unit (in other words, a superpixel 125) across a substrate surface. The repeating unit is constructed in such a way that if a colorant application error develops, one or more pixels in the repeating unit are incorrectly or incompletely colored. An arrangement of the pixels in the repeating unit renders such error less visually apparent when viewed on the substrate. <P>COPYRIGHT: (C)2012,JPO&INPIT |
