An auxiliary drive system for attachment to the ink fountain roller of an offset lithographic machine for permitting continuous rotation of the ink roller within the fountain when the machine is stopped or inactive. The auxiliary drive system includes an auxiliary motor mounted on the machine and preferably activated only when the machine is stopped. The auxiliary drive motor is drivingly connected to the ink fountain roller by a one-way clutch and clutch roller adapter which permits a slow but continuous rotational drive of the ink fountain roller when the machine is stopped, and which freely overruns to permit rotation of the ink fountain roller when the machine is activated.
