Abstract

See full text

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. When transitioning from one color to another, it is better to make smaller changes in inkings. This goal is not served when printing spot colors. Spot colors are often single, solid colors that do not vary in gradients from one to another. 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.
