The Reflected Murray-Davies Probability Model Of Fluorescent Ink Prints

The color prediction is the important issue in printing industry and practical application. The color devices using all tache in printing like from the scanning, display to proofing are an important application of prediction models. The Murray-Davies model is very important because it is the foundation of a good many prediction models. This article will starts with the classical Murray-Davies model and use the law of conservation of energy. First by taking the multiple internal reflectance in the ink layer and the light scatter in paper substrate into account even their influence on color signal we strike up a new and principle expand Murray-Davies model based on realistic physics process. Secondly, using probability function to quantitate the influence of light scatter in paper substrate to the reflectance of image and make certain which complication in printing process determined the value of scattering function. And then combine all the effecting parameter to calculate the overall reflectance of prints. Finally by cognizing the different color showing mechanism of fluorescence ink to analyse the multiple internal reflectance in fluorescence ink layer and make sure the parameter distinction between fluorescence ink and ordinary ink. And that expanding the new principle Murray-Davies model to the color prediction of fluorescence ink and establishing the Murray-Davies color prediction model of fluorescence ink. And that expanding the new principle Murray-Davies model to the color prediction of fluorescence ink and establishing the Murray-Davies color prediction model of fluorescence ink. In the last of the article we use the parameter value of other literatures to make numerical value simulation and prove the validity of new model. At last put forward the direction of future study.
