Abstract

Fluorescent brighteners in paper can emit visible blue lights or fluorescence after absorbing invisible UV (ultraviolet) lights and the visible blue lights can increase the whiteness of the paper in the visual effects. In this paper, we use the enhanced Clapper-Yule model to establish a new predicted reflectance model for halftone image. The reflective law of halftone image on fluorescent supports is generalized by utilizing the idea that the reflected light by fluorescent supports is divided into two parts: the primary streams which consist of originally incident light and the fluorescent streams which are created by absorption of the UV lights. Firstly, the spectral reflectance of the vacant fluorescent supports and ink layer on fluorescent supports are analyzed. Secondly, the reflectance and transmittance of ink layer on fluorescent supports are studied. Then the physical dot gain that results from the real extension of an ink dot (i.e., ink spreading) is studied. Finally, we establish a reflection and transmission model for a halftone image on paper with fluorescent additives. To prove the accuracy of the model, we make data simulation with Matlab software and two reflectance curves (the reflectance of halftone image on paper with and without fluorescent additives) were generated. From the results, we can make a conclusion that the new model has a good accuracy to predict the reflectance of halftone image on fluorescent supports.
