摘要:
A method and apparatus is used for gamut mapping to a printer gamut that includes receiving a narrow gamut, a wide gamut, a printer gamut for printing on a printer and a predetermined mapping between the narrow and printer gamuts, identifying overlapping areas in the wide gamut, the narrow and printer gamuts, determining when the narrow gamut overlaps areas of the wide gamut, utilizing the narrow gamut values when the determination provides overlapping areas of the narrow gamut and the wide gamuts, selecting a wide gamut interpolation point corresponding to the surface of the printer gamut when narrow gamut areas do not overlap the wide gamut according to the determination, selecting a narrow gamut interpolation point by mapping the narrow gamut to the printer gamut and interpolating the narrow gamut interpolation point and the wide gamut interpolation point expanding the narrow gamut values into the printer gamut.
