Abstract
A cup holder for rotating a doctoring ink cup includes a housing with a cup receiving chamber and a bumper extending into the chamber. The bumper contacts the ink cup to rotate it within the chamber during inking of a gravure plate. It is the relative motion of the plate and the ink cup during inking of the plate which causes the bumper to contact the ink cup. A second bumper extends into the cup receiving chamber. A method of inking a gravure plate includes inking the plate by relative motion between an ink cup and the plate, and rotating the ink cup during inking such that an edge of the ink cup in contact with the plate rotates with respect to the plate. The rotation is caused by the relative motion.
