A Drawing of Digital Printing Gamut Map

Based on the digital printing gamut map, the (Commission Internationale de L'Eclairage (CIE) data of different papers are read under the same international standard FOGRA39. In this paper, we used MATLAB programming to make visual three-dimensional color gamut map, analyze and summarize the gamut range of different paper. The color gamut map of 3D convex hull surface is drawn by algorithm, and the color gamut range of different paper under the same international standard FOGRA39 is realized. Through the data query and analysis on the drawn maps, the lab range of different paper is summarized.
