Patent ID: 8432588

Claim:
A method of mapping colors which are not reproducible by a reproduction device having a color gamut with a gamut boundary, and are therefore outside the reproduction device's color gamut, to reproducible colors, comprising: deriving by a computer, in a three-dimensional color space, a reduced gamut with a reduced-gamut boundary from the reproduction device's gamut by reducing its size in all three dimensions; determining by the computer reduced-gamut clipping-vectors by clipping the out-of-gamut colors onto the reduced-gamut boundary; mapping the out-of-gamut colors to those colors at which the reduced-gamut clipping-vectors intersect the reproduction device's gamut boundary, so that out-of-gamut colors associated with clipping-vectors of different directions that are clipped onto the same point, or adjacent points, of the reduced-gamut boundary are mapped to points spaced apart, or spaced farther apart, on the reproduction device's gamut boundary.
