Abstract
A sheet processing machine, in particular a sheet-fed printing press, includes a varnishing unit and at least one combination drier for applying radiation energy and heated air to a newly varnished sheet. The at least one combination drier includes a plurality of circular or polygonal air nozzles and narrow-band high-power infrared light sources disposed between the air nozzles. The infrared light sources apply radiation at a radiation density of at least 25 kW/min total to the varnished sheet. The temperature of the heated air passing through the nozzles is below 100° C., preferably below 80° C. A method of drying sheets is also provided.
