Claim One:
1. A method of creating a color-mapping lookup table, the method comprising: obtaining, by way of a processor, color-space data for respective solid colors specified as lattice points of the color-mapping lookup table; obtaining color-space data for respective achromatic colors specified as lattice points of the color-mapping lookup table; obtaining color-space data for boundary colors specified as lattice points of the color-mapping lookup table, the boundary colors being taken out of plural boundary colors located on boundaries of a color gamut for any of the solid colors not specified as the lattice points; obtaining color-space data for memory colors specified as lattice points of the color-mapping lookup table; creating the color-mapping look-up table by tabulating the color-space data for each of the respective solid colors specified as the lattice points, the respective achromatic colors specified as the lattice points and the respective boundary colors specified as the lattice points and respective memory colors specified as the lattice points; calculating color-space data for colors not specified as lattice points based on the tabulated color-space data for the respective solid colors, the respective achromatic colors, the respective boundary colors, and the respective memory colors; and outputting the calculated color-space data.
