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.
