 eignet, stellt man auf folgende Weise her. 



   Auf einer passenden   harten   Unterlage, z. B. einer polierten Marmorplatte, wird eine dünne Schicht eines leicht zu schneidenden Materiales, wie Wachs, ausgebreitet ; geeignet hiefür ist Bienenwachs, das entweder mit festem Paraffin gehärtet oder mit Paraffinöl odor dgl. weich gemacht wird, so dass die Konsistenz derartig ist, dass die Masse beim Schneiden weder springt noch am Messer   festklebt.   Aus dem festen Wachsblatt wird nun durch Ausschneiden und Entfernung der ausgeschnittenen Teile die Matrize hergestellt. 



  Man überstreicht die Matrize vor oder nach dem Ausschneiden, aber während sie noch auf der festen Unterlage liegt, mit einem geeigneten Mittel, um das Festkleben der Mischung zu verhindern, z. B. mit Glyzerin, dem unmittelbar vor dem Gebrauch ein wenig Stärke zugesetzt wurde. Die Matrize wird dann mit einem Rahmen umgeben und die geschmolzene und gut gemischte Masse darauf gegossen, wobei die Temperatur der Masse don Schmelzpunkt des Wachses nicht erreichen darf. Wenn die Masse erstarrt ist, wird der Rahmen umgedreht und die Matrize entfernt. Das so erhaltene Blatt ist die gewünschte Druckplatto. 



   Das Verfahren, die Matrize durch Einschneiden des Musters in eine auf harter Unterlage ruhende Schicht zu gewinnen und von dieser die Druckform abzugiessen, ist an sich bekannt und bildet keinen Gegenstand der Erfindung.

 is made in the following way.



   On a suitable hard surface, e.g. B. a polished marble slab, a thin layer of an easy-to-cut material such as wax is spread; suitable for this is beeswax, which is either hardened with solid paraffin or made soft with paraffin oil or the like so that the consistency is such that the mass neither cracks nor sticks to the knife when it is cut. The die is then made from the solid wax sheet by cutting out and removing the cut-out parts.



  The die is painted over before or after cutting it out, but while it is still on the solid surface, use a suitable agent to prevent the mixture from sticking, e.g. B. with glycerine, to which a little starch was added just before use. The die is then surrounded with a frame and the melted and well mixed mass is poured onto it, whereby the temperature of the mass must not reach the melting point of the wax. When the mass has solidified, the frame is turned over and the die is removed. The sheet thus obtained is the desired printing plate.



   The method of obtaining the die by cutting the pattern into a layer resting on a hard surface and pouring the printing form from it is known per se and does not form the subject of the invention.

 

Claims (1)

PATENT-ANSPRUCH : Verfahren zur Herstellung einer aus Harz, Schwefel, Erdwachs und allenfalls auch Ilarzöl bestehenden, zum Giessen von Druckplatten geeigneten Masse, dadurch gekenn- zeichneten, dass in geschmolzenes Harz Schwefel, dann Ozokerit und schliesslich allenfalls Harzöl eingerührt und die Mischung wiederholt in Formen gegossen und nach dem Er- starren wieder umgeschmolzen wird, bis sie vollkommen gleichmässig geworden ist. PATENT CLAIM: Process for the production of a mass consisting of resin, sulfur, earth wax and possibly also Ilarzöl, suitable for casting printing plates, characterized in that sulfur, then ozokerite and finally resin oil are stirred into molten resin and the mixture is repeatedly poured into molds and subsequently is melted again after solidification until it has become perfectly uniform.
