ABSTRACT:
For a given set of dyes, chosen to match a target (standard) color, by combining the a priori percent reflectance and concentration data of primary (calibration) dyeings with that of one or more trial dyeings, a calculated formulation can be obtained which agrees with one of the trial formulations used, or the average, as precisely as desired. A match, color or spectral, to a target color, near to the color of the trial dyeing in color space, is obtained that is, for all practical purposes, as accurate as those dyes permit.
