Abstract
A method and a device for eliminating peeled-off surface portions of an ink-repellent layer of an offset printing plate. With known plate-cylinder washing devices such peeled-off surface portions of an ink-repellent layer cannot be eliminated from the offset printing plate completely. The method and device according to the present invention enables the complete elimination of said peeled-off surface portions. Using the surface of non-woven fabric mounted on a shaft in spiral-like manner, the ink-repellent layer is brushed off without any fluid added. The method and device are used in connection with the direct imaging of offset printing plates in the dry-offset process.
