In formulations such as this, the alkaline dispersion of Zein and resin in water is modified with 40 to 100 parts of organic solvent to make it less viscous, and to produce a continuous film with high gloss when printing with the finished ink. The pigmented ink dries quickly and adheres to non-moistureproof cellophane, paper, and paperboard.
Zein inks in general are economical to use, have good gloss and resist smudging. Their rapid drying characteristics are of extreme importance and often help to decrease paper distortion, improve register and eliminate offset. |
