Description

Kopierfolien. In dem Patent 380797 ist ein Verfahren beschrieben, die Oberfläche von Folien aus durchsichtigem Zellon (Azetylzellulose) oder von ähnlichen plastischen Massen (Äthylzellulose u. dgl.), ehe sie mit Druckelementen - wie Abbildungen, Hand-, Maschinen-oder Druckschrift _ jeder Art, wie auch Noten und sonstigen Zeichen - versehen werden, einer Vorbehandlung zu unterwerfen. Die Oberfläche wurde zu diesem Zweck entweder mit einer schnell trocknenden schwachen Gelatine-. bzw. Chromatgelatinelösung überzogen oder mit Eisessig oder Azeton oder mit einer Mischung beider abgerieben und dann trocknen gelassen.Copy transparencies. Patent 380797 describes a method of surface-coating films made of transparent cellulose (acetyl cellulose) or similar plastic masses (ethyl cellulose and the like) before they are applied to printing elements - such as images, handwriting, machine or printed matter of any kind as well as notes and other symbols - are to be subjected to a pretreatment. For this purpose, the surface was either coated with a quick-drying weak gelatin. or chromate gelatin solution coated or rubbed with glacial acetic acid or acetone or a mixture of both and then left to dry.

Es hat sich nun gezeigt, daß es für viele Zwecke von Vorteil ist, von genannten Vorbehandlungen ganz oder zum Teil abzusehen und die Oberfläche der Folie so zu gestalten, daß sie beim Aufstempeln von Objekten -wie von Notenzeichen o. dgl. - von Hand unter Benutzung von Metallstempeln der glatten Metallfläche der Stempel eine gewisse Reibung bietet, so daß letztere auf der Folie nicht mehr ausgleiten und das Druckergebnis verwischen können. Diesen Widerstand erreicht man, wenn man die Oberfläche der Zellonfolie nach einem der bekannten Verfahren äußerst schwach körnt oder mattiert, indem man die Folie z. B. zwischen zweckentsprechend mattierten und erwärmten Metallplatten preßt und ihre Oberfläche direkt bedruckt oder sie vorher zum Erhalt einer glasklaren Undurchsichtigkeit der Folie mit Eisessig, Azeton, Benzol-Alkohol o. dgl. abreibt und trocknen läßt.It has now been shown that it is advantageous for many purposes to refrain from the mentioned pretreatments in whole or in part and the surface of the Make the film so that it can be used when stamping objects such as musical notes o. The like. - by hand using metal stamps of the smooth metal surface of the Stamp offers a certain amount of friction, so that the latter no longer slip on the film and can blur the print result. You get that resistance if you the surface of the Zellon foil is extremely weak after one of the known methods grained or matted by z. B. between appropriately matted and heated metal plates and presses their surface directly or them beforehand to obtain a crystal-clear opacity of the film with glacial acetic acid, acetone, benzene-alcohol or the like rubs off and lets dry.
