The invention describes a sheet offset machine in which may be applied an air-drying ink/varnish. The invention furthermore concerns a drying unit that may be used for drying air-drying ink/varnish. The drying unit is disposed in connection with a cylinder surface and includes an integrated ventilator with suction and exhaust duct. These are used for sucking in fresh air and for exhausting used air having swept a wet print on the print carrier. The ventilator is connected to nozzles having an elongated nozzle orifice oriented in parallel with the center axis of the cylinder surface. The nozzle orifice is provided immediately opposite the cylinder surface for blowing an air stream towards counter pressure on the print carrier while it is disposed on the cylinder surface. By using such a system is achieved an efficient and energy economical drying of the applied inks/varnishes.
