Size modulated stochastic screening |
摘要 |
A method for generating a screened reproduction of a multiple tone image comprises the steps of frequency modulation or stochastic screening the multiple image to obtain screened data representing tones of the multiple tone image in terms of halftone dots; reproducing the halftone dots on an imaging element by means of a scanwise exposure, wherein the size or composition of the halftone dot is modulated, by varying the number of microdots (or rels) composing a halftone dot. <IMAGE>
