Abstract
The demand for reproduction of printing color vastly expands, which significantly promotes the application of the spot-color ink. To improve the accuracy and practicability of color matching, the Kubelka–Munk color-matching theory and the improved spectrophotometric uniform color space weight factor color-matching method are applied to construct two matching models. The four-color (C, M, Y, W) model is established on the basis of three-color model (C, M, Y), and the derivations of the two models will be shown. In addition, a new experimental program is designed for ink toner to obtain the basic data of color matching. Prediction recipes are obtained by using MATLAB software for matrix arithmetic. And the accuracy and practicability of color-matching models are verified through the experiment. The results show that two models are feasible for better utility of the spot-color matching.
