发明名称 Updating a fleet CMYK to engine cmyk LUT in a color management strategy
摘要 What is disclosed is a system and method which addresses the problem of inheriting color management intent from a fleet color management LUT into a 4-to-4 cascaded LUT. The LUT is updated starting with a set of patches that either form a uniform or non-uniform grid of the LUT or can be projected to a uniform or non-uniform grid in the CMYK space using, e.g., PCA. A set of L*a*b* target as well a variable that serve the purpose of preserving the GCR and other elements of the fleet profile is obtained by passing the set of CMYK values to the fleet printer model. By iterating on the printer (or the printer model of the engine at the moment of the engine change) and converging to the targets, the engine device cmyk set is obtained. The LUT is formed between the uniform or non-uniform gridded CMYK and the device cmyk.
