Das Verfahren der Erfindung soll dazu dienen, ohne Kopieren durch einen besonderen Raster Tiefdruckformen herzustellen. Die Rasterstege sollen vielmehr einen Bestandteil der Druckplatte bilden. Die Herstellungsweise ist folgende:The method of the invention is intended to be used without copying by a particular Making grid gravure forms. Rather, the grid bars are intended to be a component the pressure plate form. The manufacturing method is as follows: Auf durchsichtige Platten aus Zellon, Zelluloid u. dgl. wird auf bekannte Art durch Prägen, Formen, Aufkleben oder AufgießenTransparent plates made of Zellon, celluloid and the like are carried out in a known manner Embossing, shaping, gluing or pouring on ™ ein wasserfestes Relieftiefdruckraster aufgebracht, in der Weise, daß zwischen den erhabenen Rasterlinien Vertiefungen in der Platte liegen. Diese Vertiefungen werden bis zur Höhe der erhabenen Rasterlinien mit Chromatgelatine ausgefüllt. Die Chromatgelatine wird von unten belichtet, d. h. das Diapositiv des zu kopierenden Bildes wird auf der Rückseite der durchsichtigen Platte angelegt, so daß das Licht durch das Dia-™ applied a waterproof relief printing grid, in such a way that there are depressions in the plate between the raised grid lines. These wells will be up Filled in with chromate gelatine to the height of the raised grid lines. The chromate gelatin is exposed from below, d. H. the slide of the image to be copied is on the back of the transparent plate applied so that the light through the slide ao positiv und durch die durchsichtige Platte in die Chromatgelatineschicht eindringt. Hierauf wird die Platte mit warmem Wasser entwickelt. Dabei bleiben natürlich die Rasterlinien, die als Stege für die Rakel dienen sollen, unverändert stehen. Die einzelnen Teile des Bildes bleiben, je nachdem die Chromatgelatineschicht mehr oder weniger Licht erhalten hat, höher oder tiefer als gegerbte Gelatine in den Tiefen zwischen den Rasterlinien zurück, so daß diese Vertiefungen mehr oder weniger Druckfarbe fassen können, je nachdem es das Bild erfordert.ao positive and penetrates the chromate gelatin layer through the transparent plate. On that the plate is developed with warm water. Of course, the grid lines remain, which are to serve as webs for the squeegee are unchanged. The individual parts of the picture remain, depending on the Chromat gelatin layer has received more or less light, higher or deeper than the tanned one Gelatin back in the depths between the grid lines, making these depressions can hold more or less ink as required by the image.
