Clapper-Yule Color Prediction Model for Recto-Verso Halftone Images
The color prediction of the halftone print with a spectral reflectance model is a subject that draws closes attention in the field of quality control and equipment check. On the approximation that the ink is non-scattering and its refractive index is nearly equal to papers, we propose a spectral reflectance color prediction model for recto-verso halftone images by making use of the theory of the light propagation in paper with long- and short-distance model and net structure of multiple reflection in the recto-verso halftone images. Then the new model is demonstrated to be correct through the theoretical analyse is. The new model provides the prediction of the color of recto-verso halftone images and a theoretical method for the development of the non-line checking instrument.
