Abstract:
A color correction system for identifying a target color from a printer gamut in a subtractive color-space that corresponds to a source color in a source color-space, said system comprising:a gamut transformation module adapted to convert said printer gamut into an equivalent gamut in said source color-space, said equivalent gamut having a plurality of non-overlapping constituent volumes, said constituent volumes sharing a common boundary point; a volume finder having access to said plurality of constituent volumes and to said source color, said volume finder adapted to identify a source-bearing volume from said plurality of constituent volumes; a volume mapper for matching a target-bearing volume in said printer gamut in said subtractive color-space with said source-bearing volume in said equivalent gamut in said source color space; and a coordinate mapper for determining a target color in said target-bearing volume that corresponds to said source color in said source-bearing volume.
