Flexographic printing inks Flexographic inks are either solvent-based, water-based, or radiation-curable 1. Their composition and properties are shown in Table 1. The viscosity of flexographic inks is low (10–200 mPa∙s) contributing to the ink flow during the printing process and improving the ink transfer 2,3. On the other hand, the low viscosity increases the ink
