Verfahren zur Herstellung zusammengesetzter Lithographiesteine.
Die für den lithographischen Farben-oder Schwarzdruck beim Druck von Riesenplakaten u. dgl. benötigten, bisher nur in flachen Platten verwendeten grossen Lithograpbiesteine werden bekanntermassen mit den für Druckzwecke erforderlichen Eigenschaften der Oberfläche nur selten vorgefunden und sind daher äusserst kostspielig. Die Beseitigung dieses Übelstandes durch Herstellung zusammengesetzter Lithographiesteine konnte bisher nicht erreicht werden, da die praktische Lösung dieser Aufgabe ein Hindemittel voraus-

Da durch das vorstehend angegebene Verfahren nicht nur flache Platten sondern

Process for the production of composite lithographic stones.
For the lithographic color or black printing when printing giant posters etc. The like. The large lithographic stones required, which were previously only used in flat plates, are known to be rarely found with the surface properties required for printing purposes and are therefore extremely expensive. The elimination of this deficiency by producing composite lithography stones could not be achieved so far, since the practical solution of this task requires a hindrance.

Partial stone surface can be etched just as evenly as that of the single stone without acid or water eating into the joints. It can also be sanded so evenly that neither lesions nor cracks appear in the joints.
