摘要： A method of defining color separation for printing an image via NPacs, the method comprising: selecting a plurality of NPacs corresponding to a plurality of points within an RGB cube to provide a tessellation in RGB space translated to a valid tessellation in an NPac-related space; and defining color separation from the selected NPacs.

摘要： In a method to generate a print specification color separation look-up table, a device color space is sampled to provide at least one sampled value. The sampled value is transformed to a device independent color space. The transformed sampled value is gamut mapped using a source color gamut and a color separation color gamut to provide a color separation value. The gamut mapping is performed in an expansion mode and a compression mode.
