Abstract

Four color printing is the common way to render a color image to paper. This four color printing has certain side effects, among them the metameric representation of colors. This means that a single visual color can be generated through multiple different four color combinations. This is normally considered a problem, however, the problem description can be inverted and information can be embedded in a printed color image that is perceptually invisible under normal illumination, but revealed to an infrared imaging system. This means that certain security aspects can now produced in an essentially cost-neutral way.
