Abstract:
1. A method of generating patterns representing a halftone image, said method comprising the generation of a first set of patterns consisting of lines and curves dimensionally modulated to produce variations in tones reproducing the halftones of the image using an intaglio rendering technique, which lines and curves define a plurality of spaces between the lines and curves, the generation of a second set of patterns consisting of microstructures that are distinct from the lines and curves of the first set of patterns, said microstructures being dimensionally modulated to produce variations in tones reproducing the halftones of the image, said microstructures consisting of stochastic microstructures forming a grain, said second set of patterns being interlaced with said first set of patterns such that said microstructures of the second set of patterns occupy the plurality of spaces between the lines and curves of the first set of patterns and so that the halftones reproduced by the second set of patterns complement the halftones reproduced by the first set of patterns, the first and second set of patterns forming two complementary sets of patterns reproducing the halftones of the image.
