Abstract

Optical brighteners in substrates have a major impact on the perception of color and in particular on the perception of halftone prints. The main objective in this context is to describe the illumination-dependent interaction of brightened substrates with inks or colorants in general. In contrast to tristimulus value approaches, the here presented brightened substrate correction on a spectral scale allows the physically founded prediction of the brightener-effects concerning arbitrary illuminations. Included are CIE standard illuminants as well as arbitrary for measurement and for color validation used light sources.
