Abstract:
1. A method of mapping spot colors within a printer's gamut comprising: (A) generating a first estimated in-gamut printer device dependent color space representation associated with an out-of-gamut target color; (B) printing the first estimated printer device dependent color space representation associated with the target color; (C) generating a first measured spot color representation of the target color by measuring the spectral properties associated with the target color; (D) executing a gamut mapping control system, wherein the gamut mapping control system generates a first set of two or more estimated in-gamut printer device dependent color space representations associated with the target color based on two or more respective gain matrices, and selects the estimated color space representation nearest to the target color as a second estimated printer device dependent color space representation associated with the target color and (E) printing the second estimated printer device dependent color space representation associated with the target color.
