CPC H04N 1/6066 (2013.01) [H04N 1/6075 (2013.01)] | 16 Claims |
1. A method for reproducing an out-of-gamut spot color on a color printer, comprising:
determining a color gamut for the color printer, the color gamut being defined by a color gamut surface in a three-dimensional color space representing the colors that can be printed by the color printer;
specifying a spot color by color coordinates in the three-dimensional color space, wherein the spot color is outside of the color gamut surface;
determining a first target color corresponding to a color on the color gamut surface having a minimum color difference to the specified spot color;
determining a second target color corresponding to a color on the color gamut surface having a hue value equal to a hue value of the specified spot color;
defining a path on the color gamut surface connecting the first target color and the second target color, wherein a control parameter having a control parameter value is used to specify a relative position along the defined path; and
providing a user interface enabling a user to adjust the control parameter to specify an aim color along the defined path for reproducing the spot color using the color printer.
