Ink Color Matching Method Based on 3D Gamut Visualization

Because the traditional computer color matching algorithm can not give people an intuitive feeling, and the color matching process is difficult to understand, aiming at the above problems, an ink color prediction method and process were established. Firstly, the relative position of the ink color gamut in the CIEL*a*b* color space was determined by using the color gamut visualization technology. Then the position of the target color in the CIEL*a*b* color space and the ink color field was found, and the ink ratio of the target color was obtained by matrix calculation using the spectral data of the base color bar. The experimental results show that the method in this paper can meet the actual printing color requirements, and it can provide a new method for ink computer color matching.
