Abstract
The invention relates to a sealing element for an ink chamber of a rotary printing press, wherein the sealing element has a sealing surface that rests against a roller body during operation of the rotary printing press. In order to reduce wear on the sealing element, the sealing surface has at least one flow outlet opening, at which an overpressure of a fluid may be built up during operation of the rotary printing press, in such a way that the fluid between the sealing surface and roller body forms a sealing flow film.
