摘要： In a method for re-imaging a printing form that has been used for printing in a prior printing process a substrate of the printing form is cleaned globally of ink or varnish and the substrate is treated abrasively globally in order to erase a preceding printing image. The substrate to be imaged with a new printing image is treated locally in image regions with a pulsed laser beam and, in the process, a nanoscopic and hydrophobic surface structure is produced locally. The substrate is treated globally with a hydrophilicity intensifier, as a result of which the substrate becomes hydrophilic locally in the previously hydrophobic image regions. An apparatus has a corresponding erasing unit and an imaging unit with a femtosecond laser.

摘要： 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.
