Abstract

The invention involves a printing press comprising a spray dampening unit 2 having a spray nozzle cleaning device 3, a spray dampening unit 2 having a spray nozzle cleaning device 3 and a spray nozzle bar 22 having a spray nozzle cleaning device 3. Said spray nozzle cleaning device 3, respectively, was produced with fluid nozzles 34 using a fluid line system 31, the use of a fluid line system with fluid nozzles to produce such a spray nozzle cleaning device and a procedure to clean the spray nozzles 23 of a spray dampening unit by means of such a spray nozzle cleaning device 3. Said spray nozzle cleaning device has been or can be assembled in a spray dampening unit, comprising a fluid line system 31 having several fluid nozzles 34 by means of which a cleaning fluid can be sprayed on the spray nozzles 23.
