Abstract

In this article optimization of water based flexography ink formulation for printing polyethylene films is investigated by the aid of Design Expert 6.06 software. Since resin, solvent and pigment are the most important components in composition of inks, which affect properties of ink, So these components are considered as factors in mixture experimental design and their effects on ink properties were studied. Measurements of some physical and mechanical properties such as viscosity, surface tension, gloss, abrasion resistance, adhesion and reversibility were carried out on ink samples. These factors and their interactions were determined and finally, the optimized area was obtained.
