An Improved Model of the Reflectance Properties of Uneven Solid Prints

Abstract

A theoretical model relating the print density and mottle of solid prints to the optical properties of the paper, the ink, the amount of ink and the unevenness of the ink distribution in the print has been developed.

The model differs from previous models in that the effects of speckle are included and in that the effects of the variables mentioned above can be clearly distinguished. The model is compatible with the assumption that stochastic processes govern the ink distribution and that the intensity of these processes may be related to the structure of the paper. Only a brief review of some results is given.
