A method for controlling the temperature of a sheet in a printing press

In a method for tempering a sheet (13) in a printing machine are in zones of the sheet (13) exit temperatures determined by measuring. In response to the sensed output temperatures segments (14) of a radiator (12) driven differently, so that the zones cooler and warmer more of the zones are irradiated weaker or not. Characterized a common final temperature, or at least a temperature homogenization is achieved in the zones.
