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.

Claims

1. A CCM calculating system for calculating a blending ratio of colorants based on stored color data, said system comprising:

an input means for inputting data of color specification values corresponding to a desired target color; and

a calculating means for calculating a blending ratio of colorants for reproducing said target color based on said input data of color specification values and said stored color data.

2. The CCM calculating system as claimed in

claim 1

comprising a server storing said color data, wherein said calculating means calculates said blending ratio using said server.

3. The CCM calculating system as claimed in

claim 1

, further comprising a color specification value displaying means for displaying color specification values included in said input data of color specification values.

4. The CCM calculating system as claimed in

claim 1

, further comprising a correcting means for correcting said color specification values displayed on said displaying means.

5. The CCM calculating system as claimed in

claim 1

, wherein said color data includes data of color chips, colorants, resins or applications.

6. The CCM calculating system as claimed in

claim 1

, further comprising blending ratio displaying means for displaying said calculated blending ratio of colorants.

7. The CCM calculating system as claimed in

claim 6

, wherein said color data includes data of costs of colorants, said calculating means provides a plurality of said blending ratios of colorants and calculates the total cost of each of said calculated blending ratios based on said data of costs of colorants, and said blending ratio displaying means displays said plurality of blending ratios arranged in the descending order or the ascending order in terms of said total cost.

8. The CCM calculating system as claimed in

claim 1

, wherein first difference of hues, lightnesses or chromas of said target color and a test sample for toning with one light irradiated is different from second difference of hues, lightnesses or chromas of said target color and said test sample with another light irradiated, and wherein said system further comprises means for calculating said blending ratio of colorants which may effectively decrease the difference between said first difference and said second difference.

9. The CCM calculating system as claimed in

claim 1

, wherein said color data is provided based on data obtained by the measurement by means of a spectrophotometer.

10. The CCM calculating system as claimed in

claim 1

, wherein said color data is provided based on data obtained by the measurement by means of a calorimeter.

11. A CCM calculating method for calculating a blending ratio of colorants based on stored color data, said method comprising the steps of:

inputting data of color specification values corresponding to a desired target color; and

calculating a blending ratio of colorants for reproducing said target color based on said input data of color specification values and said stored color data.

12. A computer-readable medium having a program of instructions for execution by the computer to perform a CCM calculation processing for providing a blending ratio of colorants based on stored color data, said CCM calculation processing comprising the steps of:

inputting data of color specification values corresponding to a desired target color; and

calculating a blending ratio of colorants for reproducing said target color based on said input data of color specification values and said stored color data.
