Abstract
In one embodiment, the present invention is a method and apparatus for matching translucent coatings of absorbent substrates. In one embodiment, a method for matching a color of a sample includes generating a plurality of recipes, each of the recipes representing a mixture of one colorant and a clear vehicle and defining a concentration of the one colorant and a concentration of the clear vehicle, applying each of the recipes to one or more absorbent substrates, determining an absorption value and a scattering value for each of the recipes as applied to the absorbent substrates, storing the recipes in a database, where each of the recipes is stored with an associated absorption value and an associated scattering value, selecting a first recipe from among the recipes stored in the database, and evaluating a quality of the first recipe as a match to the color of the sample.
