Abstract

In a method to execute a pause function of an ink printing system wherein a printing substrate web is printed with a printing unit with print bars having print heads, a real value of a web tension of the printing substrate web is measured with a web tension sensor. In a printing operation the real value of the web tension is regulated to a predetermined desired operating value of the web tension. With triggering of the pause function, the web tension is further regulated by modifying the desired value of the web tension so that the printing substrate web assumes a position at the print heads after an end of the pause function that it had before a beginning of the pause function. After the end of the pause function, the real value of the web tension is regulated again to the desired operating value of the web tension.
