Abstract: A roller cleaning device for a varnishing system in a printing press has liquid-supplying means pivotally arranged above the rollers conveying varnish. The spatial distribution of the liquid-supplying means differs over the length of the rollers. The liquid-supplying means are closer together in two edge zones than in the central zone; the liquid-supplying means in the central zone have nozzles that are spaced apart from one another at a relatively large interval. The liquid-supplying means come into operation at stopping and at the onset and cessation of printing. The liquid-supplying means in the edge zone operate, in accordance with format width, throughout printing.
