Abstract
A method of controlling the supply of ink in a printing machine wherein the ink is differently guided zonally on an ink-fountain roller transversely to the printing direction, and is transferred by a vibrator roller to a distributor roller, includes metering the ink zonally for counteracting ink transfer disturbances caused by a stroke movement of the distributor roller, so as to minimize the disturbances automatically to at least an effective extent; and a printing machine for performing the method.

A method of controlling the supply of ink in a printing machine wherein the ink is differently guided zonally on an ink-fountain roller transversely to the printing direction, and is transferred by a vibrator roller to a distributor roller, which comprises metering the ink zonally in dependence on a stroke movement of the distributor roller for counteracting ink transfer disturbances caused by the stroke movement of the distributor roller, so as to minimize the disturbances automatically to at least an effective extent.
A method of controlling the supply of ink in a printing machine, which comprises:
- metering zonally differentiated ink on an ink-fountain roller transversely to a printing direction;
- transferring the ink by a vibrator roller to a distributor roller;
- and
- performing the step of zonally metering the ink in dependence on a stroke movement of the distributor roller to counteract ink transfer disturbances caused by the stroke movement of the distributor roller.
