PURPOSE:To discharge ozone sprayed against a form printed in offset printing for preventing offset efficiency. CONSTITUTION:An ozone spray pipe 15 is connected to an ozone generator 16 through an ozone transfer pipe 17 and an air blower 18 for air blasting, and ozone is sprayed against the printing surface of a previously printed form 5', thus instantaneously curing ink. Ozone separated against the form 5' and intends to diffuse to the periphery at that time is discharge to the outdoors through each exhaust duct 21, 22 from hoods 19, 20 oppositely arranged to the upper and lower sections of the ozone pipe 15 by the suction force of an air blower 23 for suction, an electromagnetic changeover valve 25 mounted in midway of the ozone transfer pipe 17 is changed over and operated automatically to the bypass pipe 24 side when the form is not fed to a printer, and ozone is discharged directly to the exhaust duct 21. |
