Description

Verwendung der Druckplatte nach Patent 438557 Gegenstand des Patentes 438 557 ist ein Verfahren zum Herstellen von mechanisch zugerichteten Rotationsdruckplatten, insbesondere für den Zeitungsdruck, nach dem man das auf der Rückseite einer Autotypieplatte aufgebrachte, hart entwickelte Bild als Strichätzung ätzt und diese Platte dann in bekannter Weise als Formenplatte für Rotationsdruckplatten verwendet.Use of the printing plate according to patent 438557 is the subject of the patent 438 557 is a process for the production of mechanically trimmed rotary printing plates, especially for newspaper printing, after which this can be done on the back of an autotype plate The applied, hard-developed image is etched as a line etch and then this plate is etched used in a known manner as a mold plate for rotary printing plates.

Wie Versuche ergeben haben, ist die bei diesen Verfahren hergestellte Druckplatte als solche unmittelbar für Buchdruck, selbst für feine Drucke, die mit einem Raster von 48 Linien auf i qcm an aufwärts erzeugt worden sind, geeignet, vorausgesetzt, daß die Bilder auf der Vorder- und Rückseite der Druckplatte völlig zur Deckung gebracht worden sind. Es soll daher gemäß vorliegender Erfindung die Platte für diesen Zweck benutzt werden.As tests have shown, the one produced in this process is Printing plate as such directly for letterpress printing, even for fine prints made with a grid of 48 lines on iqcm upwards, suitable, provided that the images on the front and back of the printing plate are completely have been brought into congruence. It is therefore intended according to the present invention Plate can be used for this purpose.
