Abstract

The need for a color test object that guides the basic color correction adjustments of the electronic color separation scanner provides the starting point for this paper. The scope of this need, including differences in original photographic color materials, different process ink colorants and differences in the red, green, and blue responses of the various color scanners will be identified as variables. A three-element color test object evolved from a detailed analysis of this need: A "selective" neutral scale based on visual perception step-to-step differences, a neutral scale plus corresponding cyan, magenta, yellow, red, green, blue dye scales, and a set of 120 color patches (10 variations in lightness and saturation for 12 different hues) which cover the color space of the color material.
