    摘要: A method of calibrating a printer is disclosed. The printer prints a plurality of patches using know color values. At least two patches of each color are printed. The patches are measured to determine a measured color value for each patch. The measured color values are checked for validity. The printer is calibrated using only the valid measured color values.

    摘要: Method of determining a color gamut of a predetermined print system, comprising determining ink restrictions of the print system, generating all NP states of the print system, generating a convex hull of area coverages of NPs that do not exceed said ink restrictions, determining which NP states are outside of the convex hull, mapping NP states that are outside of the convex hull onto the convex hull, re-expressing the mapped NP states as area coverages of NPs, and sampling the convex hull in a colorimetrically predetermined way.

    摘要: Method of generating a CIElab to Neugebauer Primary area coverages interface for a print system, comprising selecting area coverages of Neugebauer Primaries and printing corresponding patches, measuring the CIE XYZ coordinates of the patches, converting the CIE XYZ coordinates to corresponding CIE Lab coordinates, and relating the CIE Lab coordinates to the NPacs.

    摘要: A color transformation table is constructed in an imaging device. Unsmoothed entries are placed in a table. The unsmoothed entries are replaced by smoothed entries. The smoothed entries are indexed by a color dimensional value for each color dimension in a first color space. Each smoothed entry is a color dimensional value for a color dimension within a second color space. A first unsmoothed entry is replaced with a first smoothed entry, so that the first smoothed entry is a weighted mean of a subset of unsmoothed entries. The subset of unsmoothed entries includes the first unsmoothed entry and other unsmoothed entries that are indexed by the same color dimensional values as the first unsmoothed entry for all but a first color dimension in the first color space.
