Abstract

Flexographic and rotogravure printing are two of the three predominant printing processes; the other is offset lithography. They are very similar in that they each transfer a very fluid, low viscosity ink from an ink fountain to an engraved cylinder. Foamed ink is a completely water based liquid ink that is foamed by the introduction of air at press side, and presents numerous advantages over conventional organic solvent based and water based inks. The prime advantage is that foamed inks are a completely aqueous, environmentally safe system. Another benefit is the cost savings associated with foamed ink. Ink consumption is reduced, insurance costs and solvent disposal systems are eliminated, and dryer energy consumption is reduced. Foamed ink has been successful employed in gravure printing. Because of the similar nature of the two processes and their inks, it is presumed that foamed ink would be equally effective in flexographic printing.
