Abstract
The present invention relates to a method for minimizing the effects of metamerism between a set of color standards (e.g., nitrocellulose lacquers) and inkjet printed color merchandise (e.g., paint chips) under a plurality of illuminants, including a balanced illuminant that emulates lighting conditions between cool (6500 K) and warm (2856 K) color temperatures. For each color standard, one selects an ink combination that best produces color merchandise having a minimal degree of metamerism. Innovatively, a combination of instrumental and visual tests is used to evaluate color difference for a set of color standards-color merchandise pairs under a plurality of illuminants. If a color standard-color merchandise pair fails either test then the ink combination may be adjusted.
