Abstract
The invention relates to a sheet-fed rotary printing machine with printing units for multicolor printing and at least one coating unit. An object of the invention is to provide stable quality during the coating process and to reduce contamination of coating fluids. This is achieved by providing at least one coating unit being arranged downstream of the printing units, the coating unit including a cleaning system. More specifically, each of the coating units has a rotatable applicator roller, a metering system for applying coating fluid to the applicator roller, and a cleaning wiper system which is movable into and out of contact with the applicator roller. The cleaning wiper is arranged upstream of the metering system relative to a direction of rotation of the applicator roller.
