Abstract
A security paper printing machine has a printing unit comprising at least one imaging cylinder, at the printing point of which, the printing point, in sections, of passing printing material, in a cycle of a fixed printing length with respect to the printing material feed to the printing point, can be printed with print images of a same print image length. A dryer device has a dryer comprising one or a multi-part drying unit that, in the printing material path, is downstream of the printing point. Printing materials passing through the dryer can be subjected to radiation for the purpose of drying the same. A control unit is provided for controlling the drying unit of the dryer with respect to activating and deactivating the same, which control unit is in signal connection with a transmitter providing signals representing one of the machine phase and the progress of the printing material, and which, per cycle, effectuates a switching on and off of or, at least part of, the drying unit after a sequence comprising at least one active and at least one inactive phase, in correlation with the position of one of the machine and the printing material phase.
