Description

Herstellung photographisch kopierbarer, nach einer photographischen Aufnahme mit der Hand radierter Negative. Das nachstehend - beschriebene Verfahren bezweckt die Herstellung von Negativen beliebiger Zeichnungen mit Hilfe einer gewöhnlichen Kameraaufnahme derart, daß die von den Negativen nach einem der üblichen photographischen Kopierverfahren. hergestellten Bilder den Eindruck einer Strichzeichnung oder eines Stahl- oder Kupferstiches machen. Zu diesem Zweck wird in belcinnter Weise eine durchsichtige Platte, z. B. aus Glas oder glasklarem Zelluloid, mit einer plastischen, ganz oder nahezu ganz lichtundurchlässigen Schicht überzogen.Manufacture that can be copied photographically, after a photographic one Photograph of negatives etched by hand. The procedure described below aims to produce negatives of any drawing with the help of an ordinary one Camera recording in such a way that the negatives after one of the usual photographic Copying process. produced images give the impression of a line drawing or one Make steel or copper engravings. For this purpose a transparent plate, e.g. B. made of glass or crystal clear celluloid, with a plastic, completely or almost completely opaque layer covered.

Um nun dem zeichnerisch Ungeübten oder Unbegabten die Herstellung von radierten Negativen zu ermöglichen, wird die plastische lichtundurchlässige Schicht mit einer der bekannten lichtempfindlichen Schichten. der gewöhnlichen Trockenplatten ül>erzngeii. Macht inan nun von dein darzustellenden Gegenstande reit einer so vorbereiteten Platte in der üblichen Weise eine Aufnahme unri entwickelt die Platte, so tritt das Bild im reflektierten Licht deutlich hervor, wenn man die Platte finit einem geeigneten Verstärker, z. B. dem bekannten Quecksilberverstärker, behandelt, und kann nun auch der zeichnerisch nicht Begabte in handwerksmäßiger Weise durch Tachziehen der Linien des entstandenen Bildes X bis auf den glasklaren Grund in der oben beschriebenen Weise. das Negativ zum Herstellen @-on Al>ziigeri fertigmachen, die wegen der Lichtundurchlässigkeit der plastischen Zwi-,chenschicht den T'sindruck von Haridzeicl)nungren oder Stichen machen.In order to enable the inexperienced or inexperienced in drawing to produce etched negatives, the plastic opaque layer is combined with one of the known light-sensitive layers. the usual drying plates ül> erzngeii. If the object to be represented rides a plate prepared in this way, a recording is made in the usual way and the plate develops, the image in the reflected light clearly emerges if the plate is finitely positioned with a suitable amplifier, e.g. B. the well-known mercury amplifier, treated, and can now also those who are not gifted in drawing in a craft-like manner by drawing the lines of the resulting image X down to the crystal-clear ground in the manner described above. finish the negative for production @ -on Al> ziigeri, which, because of the opacity of the plastic intermediate layer, make the impression of resin signs or stitches.
