Abstract

A sheet-fed printing machine contains a printing unit, a drier, and a sheet handling device for transporting or guiding print sheets. The sheet handling device has an opening disposed downstream of the drier in the direction of transport. A humidification device for rehumidifying the print sheets is disposed in such a way that it rehumidifies the print sheets through the opening. The sheet handling device may contain a guide plate or several guide plates.
