Abstract: Optimization of ink recipes for spot colors in printers. Often, ICC Profiles are optimized for smooth rendering of images; thus, color recipes often contain more inks than are required for matching a color when generated from a Profile.

Herein is a discussion including dividing an N-ink set into subsets, generating an ink recipe for a desired recipe in each ink subset, and selecting a subset based on predetermined criteria. Where a spot color is out of Gamut, that color is mapped to the Gamut.
