Abstract:
1. A method of color calibration, comprising: printing a first test color sample with a printing apparatus on a print medium using a nominal color setting; selecting, from a set of reference color samples not printed with the printing apparatus, a reference color sample appearing to substantially match the first test color sample, the selected reference color sample indicative of a particular preconfigured color map, in a set of preconfigured color maps, coded to reduce a color difference of the selected reference color sample relative to a color standard, wherein each of the preconfigured color maps in the set corresponds to one of the set of reference color samples; and recalibrating the printing apparatus when the selected reference color sample differs from the color standard, where the recalibrating is performed by replacing a color map used to print the first test color sample with the particular preconfigured color map, and wherein the preconfigured color maps in the set are coded prior to the selecting of the reference color sample.
