Inking system with means for milling hydrophobic liquid into water miscible ink film

Abstract

Abstract An inking system is provided for a duplicating master, of a type wherein the nonimage portions are selectively repellent to wateror glycol-based inks and the image portions accept water or glycol-based inks. The water-based ink is applied to the printing rollers of a printing press, in the usual manner. A small quantity of a hydrophobic liquid is dropped on one roller of the train of rollers of the printing press, ahead of the roller which directly applies ink to the printing master. This liquid is milled into the ink by the rolling action of the rollers. The end result is that the image areas of the printing master accept that water-based ink and the nonimage areas reject the water-based ink.
