Description

Weiche, elastische Druckplatte f ür Farbendrucke und eine Verwendungsweise. Die vorliegende Erfindung betrifft eine weiche. elastische Druckplatte, beispielsweise von Gummi, Linoleum oder einer anderen weichen, elastischen 'Masse, für lithographische Farl)eii(Irtic'#,ze.Soft, elastic printing plate for color printing and one way of use. The present invention relates to a soft. elastic printing plate, for example of rubber, linoleum or some other soft, elastic 'mass, for lithographic Farl) eii (Irtic'#, ze.

Diese Druckplatte soll insbesondere zur Herstellung von unmittelbarem Farbendruck mittels Rotationspressen auf das zu bedruckende Material. wie Papier, Blech u. dgl., Verwendung finden.This printing plate is intended in particular for the production of direct Color printing by means of rotary presses on the material to be printed. like paper, Sheet metal and the like, use.

Die bekannten derartigen Platten haben den Nachteil, daß die leeren Stellen, also die Stellen, die keine Farbe aufnehmen (lürfen, die Farbe nicht genügend abstoßen, wodurch die zu bedruckenden Bogen leicht fleckig werrlen.The known such plates have the disadvantage that the empty Places, i.e. the places that do not absorb any color (lürfen, the color is not enough repel, causing the sheets to be printed to be slightly blotchy.

Dieser VI)elstan(1 wird nach der Erfindung dadurch beseitigt, (laß man -len Gummi ider ein anderes weiches, elastisches Material z. B. mit Metallstaub, etwa Zink- oder Aluminiumstaub, oder mit -.L#letalioxyd, oder kohlen-Kalk-, oder Lithopone, oder mit in angefeuchtetem Zustande leicht farbeabstoßenclen Lacken, Farben oder trocknenden ülen in Verbindung bringt. Diese -Materialien können auch noch andere farbeabstoßende Zusatze haben. Die N-erbindung dieser Stoffe mit dem Gutnini kann durch Vermischen dieser Materialien mit dem Gummi oder durch Auftragen dieser Materialien auf die Oberfläche des Gummis erfolgen. Für den Fall, daß Metallstaub mit dem Gummi in Verbindung gebracht wird, ist es von Bedeutung, daß der Metallstaub fettfrei ist.This VI) elstan (1 is eliminated according to the invention by (let man -len rubber ider another soft, elastic material z. B. with metal dust, for example zinc or aluminum dust, or with -.L # letalioxyd, or coal-lime-, or Lithopone, or with varnishes that are slightly color-repellent when moistened, Colors or drying oils. These materials can also have other color-repellent additives. The N bonding of these substances with the Gutnini can be made by mixing these materials with the rubber or by applying these materials are made on the surface of the rubber. In the event that metal dust is associated with the rubber, it is important that the metal dust is fat free.

Eine mit den obengenannten Stoffen zugerichtete Gummidruckplatte hat in bezug auf Farbeaufnahme und Farbeabstoßen die gleich guten Eigenschaften wie ein Lithographiestein oder eine Zinkplatte. Durch Anwendung von Gerbsäure, z. B. -einer Tanninlösung, zum Anfeuchten der Gummidruckplatte wird die Wirkung noch erhöht.Has a rubber pressure plate trimmed with the above substances the same good properties as a lithography stone or a zinc plate. By using tannic acid, e.g. B. -a tannin solution, to moisten the rubber pressure plate, the effect is increased.

Die genannten Materialien können auch ganz oder zum Teil miteinander vermischt mit der Guniiniplatte in Verbindung gebracht sein.The materials mentioned can also be wholly or partly with one another mixed with the Guniini plate.

Die Druckplatte kann direkt urn den Druckinaschinenzylinder gespannt werden oder eine Unterlage oder Einlage besitzen.The printing plate can be clamped directly around the printing press cylinder or have a pad or insert.
