Abstract
A method for transforming input color values to device control signals for a color printing device having an output response that is approximately invariant for ranges of the device control signals near the maximum or minimum allowable device control signals, wherein the input color values are transformed into the device control signals that are to be used to reproduce the input color values is disclosed. The method includes determining color reproduction characteristics for the color printing device over an allowable range of input signal values; determining a full color gamut for the color printing device describing a full range of color values that can be produced by the color printing device; creating a reduced color gamut by shrinking the full color gamut; and transforming the input color values to the device control signals using the determined color reproduction characteristics of the color printing device, wherein the input color values that are outside the reduced color gamut are mapped to color values that are on or within the reduced color gamut.
