Research on Theory and Application of Computer Ink Color Matching

摘要

Spot color ink has been essential in security printing. Convenient computer ink color matching become more and more popular. The color matching model is the core part of computer color matching. It is very important to understand and master the theory of color matching. In this paper, the principle of computer color matching based on Kubellka-Munk theory was also described. Finally, four color spots (356C, 717C, 7431C, 643C of PANTONE) were measured. Color differences of formulations respectively were 1.4, 0.3, 0.5 and 0.5, which all meet the requirement of printing standard. Therefore, the accuracy of the computer color matching was demonstrated.
