Abstract
A method for controlling the temperature of a sheet in a printing machine includes measuring initial temperatures in zones on the sheet. Segments of an emitter are actuated in different ways as a function of the measured initial temperatures for irradiating cooler zones to a greater extent and warmer zones to a lesser extent or not at all. A common final temperature or at least a homogenization of the temperature is therefore achieved in the zones.
Claims10
A method for controlling the temperature of a sheet in a printing machine, the method comprising the following steps:
- measuring initial temperatures in zones of the sheet before irradiating;
- and
- individually actuating segments of an emitter as a function of the initial temperatures measured before irradiating to irradiate cooler zones to a greater extent and warmer zones to a lesser extent or not at all to attain a common final temperature or at least a homogenization of the temperature in the zones.
