Research on Prediction Model of Ink Dot Area Rate in Digital Printing Based on Normalization Method

In digital printing, color control is important factor for print quality. In this study, based on the analysis of the characteristics of the spectral reflectance curves of three primary colors of ink,the high reflectivity and low reflectivity which were associated with the ink dot areas rate were selected, and prediction model of the ink dot areas rate was presented. Using the normalized method ' the dot areas rate of the cyan,magenta ' yellow ink could be predicted by measuring the spectral re? flectance rate of the print. It will be benefited to control the ink of digital printer and the printing color. The research has im? portant reference for color high- fidelity reproduction of digital printing.
