KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. PATENTSCHRIFTPATENT LETTERING Vr 280248 -■ KLASSE 57d. GRUPPEVr 280248 - ■ CLASS 57 d. GROUP Patentiert im Deutschen Reiche vom 2. April 1913 ab.Patented in the German Empire on April 2, 1913. Die Erfindung bezieht sich auf ein Verfahren zur Herstellung von Rastern für die photomechanische Reproduktionstechnik.The invention relates to a method for producing grids for photomechanical reproduction technology. Der Raster besteht vorzugsweise aus einem Stoff, der in plastischem Zustande durch Prägung oder Pressung mit Relief versehen worden ist, wie das bekannt ist. Es werden dadurch in größerer Anzahl kleine unmittelbar nebeneinanderliegende Kegel gebildet, derenThe grid is preferably made of a substance that is in a plastic state by embossing or pressing has been provided with relief, as is known. As a result, a greater number of small ones immediately become adjacent cones formed, whose ίο Grundflächen aneinander stoßen.ίο base surfaces butt against each other. Das Verfahren nach der Erfindung besteht nun darin, daß auf den Spitzen der Körnung des Rasters ein Überzug aus Druckerschwärze o. dgl. aufgebracht wird, die in TerpentinThe method according to the invention now consists in that on the tips of the grain of the grid, a coating of printer's ink or the like is applied, which is in turpentine löslich ist. Auf diesen ersten Überzug wird ein zweiter aus Schellack aufgebracht, der nach den tiefer gelegenen Stellen der Körnung hin abfließt. Während der Überzug auf den Spitzen durch Aufwalzen hergestellt wurde, wird der Schellacküberzug vorzugsweise durch Aufpinseln angebracht, so daß er auch die tiefer gelegenen Stellen der Körnung erreicht. Die Druckerschwärze auf den Spitzen der Körnung wird dann durch Abwaschen mit einem in Terpentinöl getränkten Lappen ent- 2g fernt, so daß die Spitzen dieser Kegel des Rasters vollständig lichtdurchlässig werden und allmählich in lichtundurchlässige Stellen übergehen.is soluble. A second shellac coating is applied to this first coating, which flows off towards the deeper parts of the grain. While the coating on the tips was produced by rolling, the shellac coating is preferably applied by brushing so that it also reaches the deeper parts of the grain. The ink on the tips of the grain is then corresponds by washing with a soaked cloth in turpentine 2 g removed, so that the tips of these cones of the grid are fully transparent and gradually into opaque locations. Paten τ-An Spruch:Godfather τ-An saying: Verfahren zur Herstellung eines Rasters aus einer mit geprägten Erhebungen versehenen durchsichtigen Platte, dadurch gekennzeichnet, daß die Spitzen der Erhebungen durch Aufwalzen erst mit einer in Terpentinöl löslichen Farbmasse, dann die ganze Oberfläche mit Schellacklösung überzogen wird und schließlich die Färbmasse von den Spitzen durch Abwaschen mit Terpentinöl weggelöst wird.Method for producing a grid from a grid provided with embossed elevations transparent plate, characterized in that the tips of the elevations by rolling on only with a Color mass soluble in turpentine oil, then the whole surface with shellac solution is coated and finally the dye mass is washed off the tips is dissolved away with turpentine oil.
