I. INTRODUCTION
Paints and printing inks have much in common. Their most basic constituent is a pigment and a binder is needed to glue the pigment to the underlying surface. A solvent is usually required in order to achieve proper application viscosity and good wetting of the substrate. The solvent may be water, which is advantageous from an environmental point of view, or an organic liquid, which is usually better in terms of performance; the choice of solvent is the classical compromise issue in the coatings area.
