Abstract

A method is provided for configuring a drying device in a printing machine, in particular in a value document printing machine. The printing machine has at least one printing unit which comprises an imaging cylinder having a plurality of imaging printing elements or groups of imaging printing elements which are arranged in rows and columns on its circumference. A drying device has a dryer, by which print material, passing through the dryer, is subject to radiation. The drying device is configured for ongoing or upcoming production in such a way that the print material passing through the dryer, in order to be dried, is subjected to radiation in a plurality of tracks spaced from each other by non-irradiated tracks according to the same switch-on and switch-off sequence extending over cycle length. The configuration takes place with regard to one of a lateral position and a width of the tracks to be subject to two radiation by the dryer using product-related data or information regarding one of the number and the size and the position of value items to be printed next to each other on the print material portion and one of using data which comes from a device for image capture and an …
