Ink Transit (Gravure)

Speed prequel

When running any substrate at a higher speed, both doctor blade and inking concerns become especially critical. Windmoeller & Hoelscher President Hans Deamer believes it is essential to employ a pre-inking system for such circumstances. Some of the best systems, he elaborates, "…utilize a combination nozzle with a special driven rubber roller, which squeezes ink into the cells, and pre-wets the cylinder immediately after ink transfer and before the cylinder is immersed in the pan." High-speed cavitation, as well as streaks caused by air entrapment in the cells, are thereby eliminated.
