摘要： A method is described for generating patterns representing a halftone image, said method comprising the generation of a first set of patterns consisting of lines and curves dimensionally modulated so as to produce variations in tones reproducing the halftones of the image using an intaglio rendering technique. The method comprises the generation of a second set of patterns consisting of microstructures separate from the lines and curves of the first set of patterns, said microstructures being dimensionally modulated so as to produce variations in tones reproducing the halftones of the image. According to a first aspect of the invention, the microstructures consist of stochastic microstructures that can be likened to a grain. According to a second aspect of the invention, the microstructures consist of repetitive microstructures reproducing information that can be recognized by an observer, which repetitive microstructures comprise microletters and/or microsymbols. The second set of patterns is interlaced with the first set of patterns in such a way that the microstructures of the second set of patterns occupy the spaces between the lines and curves of the first set of patterns and so that the halftones reproduced by the second set of patterns supplement the halftones reproduced by the first set of patterns.
