ABSTRACT:
A gas is generated from a printing plate by exposure of the printing plate. A gas diffusing suction unit jets air from air jet ports to diffuse the gas generated from the printing plate by irradiation of laser light. The gas diffused by the air is sucked along with the air from a gas suction opening of the gas diffusing suction unit. At this time, a gas suction velocity is set to 1.2 or more times an air jet velocity to suck the gas/air efficiently. The gas/air may be sucked efficiently by setting a volume of suction to 30 or more times a volume of air jet.
