Patent ID: 8599432

Claim:
A method for adjusting a color printer gamut of a printer to encompass a selected spot color, comprising: identifying by a digital front end (DFE) the selected spot color as not producible with a first color gamut of the printer; comparing by the DFE the identified selected spot color to predetermined spot colors identified as reproducible by the printer in a color set point index table; identifying by the DFE a set of set points from the set point index table corresponding to a nearest matching predetermined spot color, the identifying including: comparing a Euclidean distance between the identified selected spot color and colors in the set point index table, and determining the nearest color as one having a smallest Euclidean distance; setting by the DFE the printer to the identified set of set points, the setting including: adjusting a value for at least one print process parameter corresponding to that of at least one set point of the nearest matching predetermined spot color for achieving the identified selected spot color outside of a nominal printer gamut; and, calibrating by the DFE the printer to print the identified selected spot color.
