发明名称 Multi-ink vector halftoning using multi-bit vector halftoning methods
摘要 According to exemplary methods, a print job including an electronic document having a color image is received into a computerized device having a marking device including a print engine. A sheet of the print job is analyzed by the computerized device. In the analysis, a contone of the color image is converted to multi-bit output using multi-level vector halftoning. Pairs of complementary colors are selected, and substitute color channels for drop sizes are determined for each pair of complementary colors. Binary vector halftoning is applied using the substitute color channels for each pair of complementary colors. It is determined if ink is to be printed for the complementary colors. Multi-level processing is applied to determine an amount of ink for one color of each of the pairs of complementary colors. Pixels of the color image are rendered using the ink amount for the color of the pair of complementary colors.
