Patent ID: 8870324

Claim:
A method to execute a print interruption in a printing operation of an ink printing system with at least one printing apparatus wherein a printing substrate is printed to with a printing unit with at least one print head, comprising the steps of: with aid of a sensor, generating print clock pulses that are supplied to a print controller depending on a feed of the printing substrate; with triggering of the print interruption, reducing a feed speed of the printing substrate from a print speed in the printing operation to a predetermined speed according to a deceleration ramp, and after the print interruption accelerating the printing substrate again to the print speed according to an acceleration ramp; given occurrence of a print clock pulse during at least one of the ramps, sending with the print controller at least one vibration pulse to the at least one print head so that at least one cycle of vibration oscillations is implemented at said print head; and generating the at least one vibration pulse if a time interval of the print clock pulses relative to one another reaches a predetermined value.
