摘要： A color-separation LUT and/or algorithm method and apparatus preferably convert input device-color data to output device-colorants, for many color-presentation types—automatically and for arbitrary colorant-set. In one major aspect of the invention, a device-hue ring is defined along six straight edges of a cubical device-hue space (without segments ending at white and black). Preferably coordinates defined along the six segments parametrize the procedure and equipment, i. e. establish colorant indexing by those coordinates (and preferably device-hue). In a second major aspect, plural color transformations—having respective favorable and adverse characteristics—serve different portions of input color space; their outputs merge to combine favorable properties of the transforms. In a third, cusps of the colorant hue planes populate the output side of the hue ring. In a fourth, a colorant sampling technique (faster by several orders of magnitude than exhaustive sampling) canvasses the output space.

摘要： The disclosure describes methods for color printing, performing a color separation process and performing a halftoning process. Furthermore, the disclosure describes the color separation process determining one or more Neugebauer Primaries, tessellating the Neugebauer Primaries, and generating one or more Neugebauer Primary area coverage vectors, whose area coverages are linear with respect to a device-independent color space. The disclosure further describes that the color separation process communicates with the halftoning process using one or more Neugebauer Primary area coverage vectors.

摘要： A method is provided of reproducing continuous tone pixel colors of a color image having many pixels based on Kueppers' device states, wherein the Kueppers' device states of a printing device are the printed pixel colors that are allowed based on Kueppers' color separation and halftoning. The method includes selecting a Kueppers' device state in the proximity of a continuous tone pixel color to be reproduced from the printing device's set of Kueppers' device states, and printing the Kueppers' device state. An error is diffused between the continuous pixel color and the selected Kueppers' device state to one or more pixels in the neighborhood.

摘要： A method of printing using variable pixel replication factors involves generating from an input image a reference image and a plurality of half-tone source images generated at different resolutions of the input image and with post-halftoning pixel replication factors applied such that the half-tone source images are all the same size. A pixel-replication factor selector function is applied to each reference pixel of the reference image to determine a respective source image for that reference pixel. Thus, different reference pixels correspond to different pixel replication factors. A print-state image is assembled by applying to each print-state image pixel the print state of the corresponding source pixel in the corresponding source image. The print-state image is then printed to a print medium.
