US Patent 10079960 System and method for halftoning in a print system

A print system may include a print engine, a processing device and programming instructions to halftone an electronic document to be printed. The system may receive an input image representing the electronic document to be printed, use a first and second threshold array, which are flipped to each other, to halftone the input image to generate a first and second set of data, respectively, then combine the first and second set of data to generate a halftoned image. In combining the first and second set of data, each dot in the halftoned image may represent full saturation if the corresponding dot in at least one of the first and second set of data represents full saturation, or white if the corresponding dots in both the first and second set of data are white. The system may use the same halftoning method for a monochrome or color document.
