Paper Abstract

A probabilistic model for the interaction of light beam with a color imprint was developed; the probability of scattering, reflection, absorption and transmission of light beam by components of imprint is investigated.

The values of the optical density of prints and reverse side on the areas with and without watermarks were obtained with different amount of ink. Correlation analysis of the interconnection between the structural characteristics of the paper and the optical characteristics of the print and its return revealed the likelihood of interaction of light beam with the structural elements of paper and ink.
