Abstract:
What is disclosed is a novel system and method for obtaining optimum CMYK values for spot colors, with significantly lower computational effort, by using a set of printer profiles with different pre-computed GCR strategies. Various versions are discussed on how to utilize and/or choose among these profiles for each spot color. The present invention is applicable to spot color emulation for CMYK as well as N-color printing, and can be used to optimize one or more image quality attributes, including graininess, mottle, color stability, ink cost, etc. Various embodiments are disclosed.
