Abstract
In some examples, an ink feed system for providing and feeding printing ink to an inking unit of an intaglio printing unit includes an inking device in the inking unit for inking a first inking unit cylinder. A provision device includes a storage receptacle with an ink reservoir of printing ink that is fed via an outlet and a line to the inking device. Furthermore, a wall of the storage receptacle encompassing the outlet can be heated and/or a metering device may be provided in the line path to support and/or effectuate delivery of the printing ink from the storage receptacle. On an output side, the metering device may provide a mass flow or volume flow that correlates with a working speed of the metering device via a defined relationship, and the metering device may be connected to a control device to control the working speed of the metering device.
