摘要: This disclosure relates generally to methods and systems for color management in image/text printing or display systems, and more particularly to a system and method for automatically achieving spot color production through use of a plurality of gain matrices per spot color in determining spot color coordinates. Furthermore, this disclosure provides a means for mapping out-of-gamut target spot colors substantially near a boundary of the gamut of an image output device, such as a printer or display.

摘要: A methodology is disclosed to achieve adaptive illumination independent matching of spot colors. In one embodiment, the methodology includes an iterative process to determine a variety device specific recipes for spot colors across different illumination spectra, and then automatically choosing and/or recommending the optimal recipe that provides the lowest color dispersion across a variety of illuminants under consideration. This approach may be used with a variety of gamut mapping techniques. According to a further embodiment, the methodology may be used with a ray-based gamut mapping method.
