Computer Color Matching System (CCMS) | Functions & Advantages

First in 1963, ICI, Dyestuff division established the Computer System for color match prediction in their lab, but it was for their customer only.
Later in 1973, ICS (international color system), manufactured computer matching system commercially.
The basic three things are important in CCMS: -

1. Color measurement Instrument (Spectrophotometers).
2. Reflectance (R%) from a mixture of Dyes or Pigments applied in a specific way.
3. Optical model of color vision to closeness of the color matching (CIE L*A*B).

Functions of Computer Color Matching System:

The following works can be done by using CCMS -

1. Color match prediction.
2. Color difference calculation.
3. Determine metamerism.
4. Pass/Fail option.
5. Color –fastness rating.
6. Cost Comparison.
7. Strength evaluation of dyes.
8. Whiteness indices.
9. Reflectance curve and K/S curve.
10. Production of Shade library. Etc.

Advantages of Computer Color Matching System (CCMS)

Computer Color Matching System (CCMS) has lots of   great advantages in Textile Industry. See some examples below –

1. Customers get the exact shade wanted with his knowledge of degree of metamerism.
2. Customers often have a choice of 10-20 formulation that will match color. By taking costing, availability of dyes, and auxiliaries into account, one can choose a best swatch.
3. 3 to 300 times faster than manual color matching.
4. Limited range of stock color needed.
