It developped the Kubelka-Munk model and established a prediction model of fluorescence prints.Based on this,it
was developped to the halftone prints and we introduced the scattering probability function which was calculated by the
experience probability model. So we can establish an complete prediction model of halftone fluorescence prints.
In 1931, Kubelka and Munk introduced two-flux Kubelka-Munk model based on radiative transfer
theory. But the model has lots of strict conditions. In 1942, Saunderson introduced revised method,
for there would occur multiple inside reflection in the interface of print, and it would induce density
increase in the ink layer, and influenced prediction precision. Dot gain is always the difficult problem
in print, it includes physics gain and optical gain. Kubelka-Munk model didn't consider dot gain's
effect, especially optical gain. There are many methods to calculate dot gain. Many of them are based
on point spread function principle. Recently, Yang Li corrects the scattering coefficient S and
absorption coefficient K in the Kubelka-Munk model based on statistical physics theory. This
makes the model has more widely applications. This article, taking into account of oil layer, oil
penetration layer and paper layer respectively, thinking over multiple reflection and optical dot gain,
builds a new halftone color prediction model.
