The side walls (2) of the ink fountain (1) bear with their front edge on the circumference of the ductor roller (4) solely in the region of the entry face (2a) and of the exit face (2c), whilst the intermediate middle region (2b) forms with the ductor roller (4) a crescent-shaped gap. The maximum width of this gap amounts to between 0.2 and 0.5 mm and is selected in dependence on the viscosity of the ink such that no ink can escape, but a build-up of ink which could press the front edge of the side walls away is prevented from occurring during operation.
