Abstract: This paper makes a great investigations, analysis and researching on color digital images and the modeling theory of analytic hierarchy process.Based on the theory and principle of color reproducing in color digital images copy process,a index system evaluating the quality of digital images color reproducing is presented. Referring to the national or trade standard, a relative judge standard of qualitative and quantitative index is given. Using the analytic hierarchy process in mathematics, it establishes a mathematics modeling of quality synthetical evaluation of digital images color reproducing, and designs a set of mathematics methods of synthetical evaluating color copying and processing.Finally,using VB to design panel,it basically realizes the simulated evaluating color digital images in computer,gives a systematic and fixed quantity way for color's reproduce for color digital images.
