Abstract:
1. A method to execute a printing interruption in a printing operation of an ink printing system with at least one printing apparatus, in which a printing substrate is printed to with a printing unit with at least one print head, and depending on a feed of the printing substrate, print clock pulses are generated with aid of a sensor arranged before the printing unit of the printing apparatus, said print clock pulses being supplied to a printer controller, comprising the steps of: during the printing interruption in which a feed speed of the printing substrate web comes from a speed for said printing operation to a standstill, given occurrence of a print clock pulse sending with the printer controller at least one vibration pulse to the at least one print head to trigger vibration oscillations without ejecting ink before said printer controller loads print data associated with the print clock pulse into the at least one print head; sending a print-start signal to said at least one print head during said interruption; and after said standstill, the feed speed of the printing substrate web is accelerated again upon resumption of the printing operation.
