Abstract
Functional relationships are derived between print-through (and its components) in newsprint and the fundamental sheet properties of grammage, light scattering coefficient and reflectance factor. The derivation follows the introduction of the concept of pigment penetration depth, together with expressions for the changes in the scattering and absorption coefficients caused by the ink interaction with the fibre network of the paper.
Values calculated using the derived equations are compared with experimental data. The agreement seems acceptable.
