Color matching model in view of Lambert-Beer law in gravure

On the basis of Lambert-Beer law and the theory of light ray propagation, the color-matching-model in gravure related to the substrate and three primary printing ink-cyan, magenta and yellow was established in this paper. The results shown that by using color difference formula CIEDE2000, the difference between calculated color value and target color value was less than 6 and almost no significant differences existed between calculated mixing formulas and presupposed ones.
