Description

Es ist bekannt, kinematographische und photographische Filme auf den Rändern mit Signierungen durch Belichtung, Aufdruck, Prägung oder Einwirkung von chemischen Reagenzien auf die Emulsionsschicht zu versehen. Diese Signierungen haben den Nachteil, daß sie nach den beim Gebrauch des Films unvermeidlichen Beschädigungen des Randes ganz oder teilweise nicht mehr erkennbar sind. Außerdem reicht bei verschiedenen Schmalfilmen, z. B. beim o^/g-mm-Film, der freie Rand nicht aus, um irgendwelche Signierungen darauf anzubringen..It is known to have cinematographic and photographic films on the edges To provide markings by exposure, printing, embossing or the action of chemical reagents on the emulsion layer. These markings have the disadvantage that after the inevitable damage to the film when using the film Edge are completely or partially no longer recognizable. In addition, it is enough for various Cine films, e.g. B. with o ^ / g-mm film, the free edge is not enough to put any markings on it.

Erfindungsgemäß wird der Film innerhalb oder außerhalb der Bildfläche mit einer Signierung versehen, die aus Buchstaben oder Zeichen in Form von mattierten Flächen besteht, wobei· die Mattierung so gewählt wird, daß sie in der Aufsicht gut erkennbar ist, bei der Projektion aber nicht stört. Kennzeichnungen dieser Art sind nicht nur für den kinematographischen Film, sondern auch für photographischen Film geeignet, sofern die Signierung kein Kopierlicht absorbiert.According to the invention, the film is marked with a signature inside or outside the image area provided, which consists of letters or characters in the form of matted surfaces, where · the matting is chosen so that it can be easily seen from above but does not interfere with the projection. Markings of this kind are not just for that cinematographic film but also suitable for photographic film provided the Signing does not absorb copy light.

Die neue Signierung, die sowohl auf der Bildseite wie auf der Rückseite des Films angebracht werden kann, besteht aus einer Aufrauhung der Oberfläche, die durch mechanische Mittel oder durch Behandlung mit geeigneten Flüssigkeiten erzeugt wird. Wesent-Hch ist, daß die Mattierung zwar am Film für das Auge gut erkennbar ist, aber das Kopier- bzw. Projektionslicht nicht in nennenswerter Weise schwächtThe new signature, both on the picture side and on the back of the film consists of a roughening of the surface caused by mechanical Means or by treatment with suitable liquids. Essential Hch is that the matting is clearly visible to the eye on the film, but the copy or projection light is not in noticeably weakens

Beispielexample

Die Mattierungssignierung wird in der Weise erzeugt, daß man die gewünschten Zeichen auf die Filmrückseite mit Hilfe von Prägestempeln (in einfacher Tiefprägung oder in Riffel- oder Pyramidenkornprägung) aufprägt oder mit Hilfe von mit Aceton oder einem anderen geeigneten Lösungsmittel befeuchteten Typen aufdruckt.The matting mark is created in such a way that one of the desired Marks on the back of the film with the help of stamps (in simple deep embossing or in corrugated or pyramid grain embossing) or with the help of with acetone or another suitable solvent-moistened type.

In der beiliegenden Zeichnung ist die Signierung in der Fläche des obersten Bildfeldes angedeutet.In the accompanying drawing, the signature is in the area of the uppermost image field indicated.
