<p>A system and method of cleaning a printing cylinder surface, wherein solid carbon dioxide is incorporated into an air stream, through a nozzle (101), and impinged on the printing cylinder surface. An exhaust tube (105) may be present to evacuate materials removed by impacting the solid carbon dioxide on the printing cylinder surface. The nozzle (101) and exhaust tube (105) may be reciprocated over the printing cylinder surface to enable a more thorough and efficient cleaning operation. A sensor (122) and control unit (130) may be optionally present. The sensor would sense the thickness of a film being cumulatively deposited on the printing cylinder surface and generate a signal when the film reached a predetermined thickness. The control unit (130) would initiate the cleaning operation in response to the signal from the sensor (122).</p> |
