Abstract
A ventilation and drying equipment for printing machines, including ovens operable to dry solvent on a printed support travelling through the ovens passages into and out of the ovens through which false or ambient air can enter the oven from the outside. At least one false air suppression device for which each printing unit covers at least one of the passages and which is maintained at a pressure lower than the air pressure inside the oven, to prevent false air from entering the oven through the at least one passage. Each false air suppression device is connected with a common recirculation duct in order to share the false air coming from each printing unit with the whole press.
