Abstract
A rotogravure inking system uses an ink trough to apply ink to a printing cylinder that dips into ink in the ink trough. The ink trough has a length less than the length of the printing cylinder. Projecting end portions of the printing cylinder are not supplied with ink from the ink trough. Thus end faces of the printing cylinder will not receive any ink and will not throw off the ink thereby eliminating ink spattering and the associated spatter protection shields.
