    摘要: A method of preparing effect pigment color formulas matched to a color original, comprising the steps of(a) producing a calibration series for each pigment included in the coloring system of an effect pigment color original,(b) experimentally determining the reflectances Rλ of the color original and of the calibration series,(c) calculating the optical parameters of the color original and of the constituents of the coloring system,(d) selecting a suitable starting formula,(e) determining the residual color difference between the starting formula and the color original,(f) producing a first matched color formula,(g) and repeating steps (e) and (f) until the residual color difference between the matched color formula and the color original is acceptable,which involves (i) transforming the reflectances Rλ of the color original and of the calibration series by means of a suitable mathematical function such that all of the transformed reflectances R′λ lie between 0 and 1, and (ii) calculating the optical parameters in accordance with the Kubelka-Munk approximation, using the transformed reflectances R′λ.
