Abstract:
The purpose of this research to study the available theories and applied technique for the color matching, to design and propose system (software) that enable to carry simple color matching function, MATLAB the language which used in this research.
MATLAB famous programming language corresponding to matrix's in it work, if color should be analysis according to the wavelengths color would be in number type for example in λ400, the color have specifications and this specifications should be different in other wavelengths, and according this numbers the color should be remove to matrix's and enter computer and by MATLAP calculation of some color should be done and the results should be given .
In textile industries to obtain any color three, four or more colors should mixed together, any color have special specifications . The one of the big problems in textile industry how to obtain the exact color, if the customer want special color that required many trail to obtain exact color, long time and many chemicals and money should be lost, by computer time, chemicals and money should be kept.
To obtain perfect color many colors should be mixed according to absorption of any color at different wavelengths and then Kubelka - Munk equations should be used, if Kubelka - Munk equations used target standard should be found to compare it with obtain color.
In calculation absorption of color should be calculated sixteen times according to sixteen wavelengths (λ400, λ420, λ440, …λ680, λ700,), the maximum absorption should be selected and then numbers remove to matrix solved by MATLAB.
After the equation solved by Kubelka - Munk the results given in numbers this number meant concentration of three colors, mixture of this color by certain concentration given obtain color.
