Embodiment Construction

[0036] Embodiments of the present invention will be described with reference to the drawings.

[0037] FIG. 1 is a block diagram showing a specific hardware structure of a CCM computing system according to an embodiment of the present invention. As shown in FIG. 1 , a client 10 is connected to the Internet (World Wide Web) 12 through a server 11 of a provider, and a web server (web server) 14 is connected to the Internet 12 . That is, the client 10 and the web server 14 are connected to each other through the Internet.

[0038] The host computer 1 executes a program, and uses predetermined system programs to adjust and monitor the execution of the program. For example, a computer has a CPU (Central Processing Unit), RAM (Random Access Memory), ROM (Read Only Memory), and a built-in or external hard disk HD mounted on a system board. The computer is designed so that the CPU appropriately reads a desired program from the HD 3 and executes a desired process using the program. ...

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 input data of color specification values and stored color data. The system has an input device for inputting data of color specification values corresponding to a desired target color; and a data operation unit 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. Such CCM calculation may be performed without the necessity of a spectrophotometer.

Description

technical field [0001] The present invention relates to a CCM (Computer Color Matching) system, a CCM calculation method for calculating a mixing ratio of colorants for reproducing a desired target color. Background technique [0002] Existing CCM computing systems are stand-alone and include a spectrophotometer for measuring color and a computer system for storing a database of colorants and a program for calculating the mixing ratio of the colorants. Such an existing CCM calculation system calculates the mixing ratio of the colorant using a database of colorants and a program for calculating the mixing ratio based on colorimetric data measured by means of a spectrophotometer. [0003] While a spectrophotometer can provide highly accurate colorimetric data for flat samples, it cannot provide colorimetric data for samples with curved surfaces or very small samples. Thus, the mixing ratio of the colorants could not be calculated due to lack of colorimetric data. Alternative...
