Claims (1)

Patent- Anspruch :Patent claim: Verfahren zur Herstellung von Tiefdruckformen durch Durchätzung von Pigmentbildern nach Rastrierung der Druckflächen (Platten und Walzen), dadurch gekennzeichnet, daß zunächst auf die Druckplatte auf photographischem Wege oder durch mechanischen Umdruck ein punktrasterförmiger, elektrisch isolierender Überzug aufgebracht wird und dann die freibleibenden Linien auf galvanischem Wege mit einem solchen Metallüberzug versehen werden, welcher dem später anzuwendenden Ätzmittel widersteht, worauf das Pigmentbild aufgebracht und die Durchätzung vorgenommen wird.Process for the production of gravure forms by etching through pigment images after locking of the printing surfaces (plates and rollers), characterized in that initially on the printing plate by photographic means or by mechanical transfer printing a dot-grid-shaped, electrically insulating coating is applied and then the lines that remain free are galvanically applied such a metal coating, which resists the later to be applied etchant, whereupon the pigment image applied and the through-etching is carried out.
