Abstract: The object of the invention is to provide a CCM calculating system being relatively inexpensive and alleviating the necessity of a spectrophotometer, a CCM calculating method and a recording medium. A CCM calculating system according to the invention calculates a blending ratio of colorants based on stored color data 16. The system has an input device 5(20b) for inputting data of color specification values corresponding to a desired target color; and a data operation unit 1(20c) for calculating a blending ratio of colorants for reproducing the target color, based on the input data of color specification values and stored color data. Since the blending ratio of colorants for reproducing the desired target color may be calculated based on the input color specification value data and stored color data, such CCM calculation may be performed without the necessity of a spectrophotometer.
