Abstract
Systems and methods for extended gamut printing. A print job is received into a print engine having a processor and a limited number of receptacles for colorant extension attachments that can be used in addition to a standard color gamut. The processor analyzes a page of the print job for the color gamut and for the color gamut with each possible gamut extension colorant. The processor calculates gamut distances for the color of each pixel outside of the color gamut for every gamut colorant extension. The gamut distances are the distances from the color of the pixel to a boundary of the color gamut. The processor calculates a sum of the gamut distances. For each pixel on the page outside of the color gamut, the processor selects an extension colorant attachment to attach to the limited physical receptacles based on having the greatest sum of the gamut distances.
