Abstract:
A process for assigning liquid colorants to individual pixels within a superpixel, said pixels being arranged within said superpixel in an array comprised of columns and rows, wherein each of said pixels is assigned at least one process color and wherein said superpixel, when appropriately tiled across a pattern area on a substrate surface, effectively simulates the appearance of a desired fill color within said pattern area, said method comprising the steps of:a. defining an array comprised of rows and columns of individually colorable pixels, each row and column containing at least two pixels; b. assigning a color to each of said individual pixels comprising said defined array, said assigned pixel colors collectively forming a desired fill color within said array when said array is observed from a distance at which said individually assigned pixel colors are visually indiscernible, and wherein all side-wise adjacent pixels along any row of said array will be assigned different colors; c. configuring a plurality of said arrays in adjacent relation to form a superpixel capable of being tiled across said substrate surface to form said fill color, said superpixel being configured so that, when tiled within a pattern area on said substrate surface, every assigned pixel color within said superpixel appears in every column defined by said tiled superpixels within said pattern area.
