The ink metering device has metering elements pressable against the ink duct roller through the intermediary of a foil covering the metering elements, the foil being fastened so as to be movable tangentially to the ink duct roller. A device is provided for holding the foil, and an adjusting device is coupled with a motorized drive an engageable with the foil holding device for progressively moving the foil tangentially to the ink duct roller at a substantially uniform feed rate so as to dispose succeeding locations of the foil at a given distance from the ink duct roller corresponding to the width of the respective ink gap.
