ABSTRACT:
A method of generating a reduced color gamut boundary for a color output device using three or more colorants, wherein the amount of each colorant is controlled by a colorant control signal vector, including determining a forward device model for the color output device relating the colorant control signal vector to the corresponding output color; determining a complete color gamut boundary for the color output device, comprising a set of color gamut boundary points; and determining a set of candidate colorant control signal vectors for each point in the complete color gamut boundary. The method also includes selecting a preferred colorant control signal vector.
