ABSTRACT:
Mapping an image comprised of a plurality of pixels from color to black-and-white includes determining, on a pixel-by-pixel basis, the amount of a plurality of color components in a color image. Each color component is applied to its own halftone screen, each screen being comprised of a plurality of cells. Certain cells areas of each screen having been allocated to a single color component to yield texture patterns. The halftone screens of the color components are combined to yield a black-and-white textured image.
