  • User-preferred reproduction of out-of-gamut spot colors
    Patent number: 11812005
    Abstract: A method for reproducing an out-of-gamut spot color includes determining a color gamut for a color printer, and specifying a spot color by color coordinates in a three-dimensional color space. A first target color is determined corresponding to a color having a minimum color difference to the specified spot color, and a second target color is determined corresponding to a color on the color gamut surface having a hue value equal to a hue value of the specified spot color. A path is defined on the color gamut surface connecting the first target color and the second target color, wherein a control parameter is used to specify a relative position along the defined path. A user interface is provided enabling a user to adjust the control parameter to specify an aim color.

  • Reproducing out-of-gamut spot colors on a color printer
    Patent number: 11711483
    Abstract: A method for reproducing an out-of-gamut spot color includes determining a color gamut for a color printer, and specifying a spot color by color coordinates in a three-dimensional color space. A first target color is determined corresponding to a color having a minimum color difference to the specified spot color, and a second target color is determined corresponding to a color on the color gamut surface having a hue value equal to a hue value of the specified spot color. A path is defined on the color gamut surface connecting the first target color and the second target color, wherein a control parameter is used to specify a relative position along the defined path. A control parameter prediction function is provided which computes a predicted control parameter value as a function of color coordinates. The predicted control parameter value is used to determine an aim color for reproducing the spot color.
