Description

Verfahren, Autotypien herzustellen. Das vorliegende Verfahren bezweckt, auf einfache und schnelle Weise Autotypien herzustellen.Process of making autotypes. The purpose of the present proceedings is to to produce autotypes in a simple and fast way.

Im folgenden sei der Arbeitsgang des Verfahrens beschrieben.The operation of the method is described below.

Es wird zunächst - entweder nach der Natur oder nach einem Bilde - eine Halbtonaufnahme hergestellt und auf diese vor dem Entwickeln im Kopierrahmen oder in der Kamera ein Raster kopiert. Das entwickelte Negativ wird in bekannter Weise auf eine lichtempfindliche Metallplatte o. dgl. kopiert und darauf auf die dergestalt belichtete Platte ein Raster kopiert. Bei beiden Kopierprozessen kann die Reihenfolge natürlich auch umgekehrt sein und der Raster zuerst kopiert werden. Beide Raster sind zweckmäßig Skalenraster; einer von ihnen muß ein Skalenraster sein, da sonst ein Bild ohne Tonreichtum entstehen würde. Als günstigste Kombination hat sich für das Kopieren auf das Negativ ein Kornraster mit natürlichem Korn, für das Kopieren auf die :Metallplatte ein Skalenkreuzraster erwiesen.First of all - either according to nature or according to an image - a halftone recording made and on this before developing in the copy frame or copied a grid in the camera. The developed negative becomes known in Way on a photosensitive metal plate o. The like. Copied and then on the plate exposed in this way is copied a raster. With both copying processes the order can of course also be reversed and the grid should be copied first. Both grids are practical scale grids; one of them must have a scale grid otherwise a picture without richness of sound would result. As the cheapest combination has used a grain grid with natural grain for copying onto the negative the copying on the: metal plate turned out to be a scale grid.

Es wird betont, daß das gesonderte Kopieren von Rastern und Skalenrastern bekannt ist. Bei dem vorliegenden Verfahren ist aber neu, daß sowohl das Negativ als auch die zu ätzende Platte mit je einem Raster bzw. Skalenraster belegt werden, worin auch die technische Weiterführung besteht. Alle Schwierigkeiten, die sich bisher dem Laien bei der Herstellung von Autotypien boten, werden durch diese Kombination beseitigt. Schatten und Licht sind ohne Schwierigkeiten richtig und fachgemäß zu zerlegen, und das in so kurzer Zeit, daß insbesondere die Ansprüche der Zeitungen restlos befriedigt werden.It is emphasized that the separate copying of grids and scale grids is known. What is new in the present process is that both the negative as well as the plate to be etched are each covered with a grid or scale grid, What is also the technical continuation. All difficulties that arise previously offered to laypeople in the production of autotypes are made possible by this combination eliminated. Shadows and light are correct and professional too without difficulty dismantled, and in such a short time that especially the claims of the newspapers be completely satisfied.
