Method and device for regulating the temperature in a laser-operated printing plate imaging unit of a printing press, particularly of an offset printing press
 A method for regulating the temperature in a printing plate imaging unit of a printing press, particularly an offset printing press, the imaging unit being operable with laser light generated by a laser diode unit which is switched on and off in accordance with an image pattern to be produced on the printing plate, includes operating, alternatively with the laser diode unit, a heat source arranged near the laser diode unit so that the temperature of the laser diode unit is as constant as possible.
