  • Ink printing apparatus, and method to control the driving of a printing apparatus
    Patent number: 9259950
    Abstract: A printing unit prints to a pre-folded substrate web. An intake unit is at an intake of a transport arrangement. A synchronization sensor is at the transport arrangement between an infeed roller and the printing unit. The synchronization sensor emits a synchronization signal when a fold of the web is present at the synchronization sensor for synchronization of a printing operation with feed of the web. A path between the synchronization sensor and a freely accessible point of the intake unit is designed such that a fold is present at the synchronization sensor when the printing substrate web has a fold at the accessible point. A relative humidity sensor is at the printing unit. A relative humidity measured by the sensor is compared with a relative humidity of an input stack. Given a deviation a length change of the web between the synchronization sensor and the accessible point is calculated, the web being displaced by the length change at the accessible point.
