Description

Verfahren zur Ausgleichung des Kornes von Transparenten. Den Gegenstand der vorliegenden Erfindung bildet ein Verfahren, um das Korn oder die sonstigen Fehlerstellen bei transparenten oder halbtransparenten Körpern aufzuheben. Insbesondere dient das vorliegende Verfahren dazu, Papier, Leinwand oder ähnliche Materialien, wie sie in Bändern oder Streifen für photographische Zwecke benutzt werden, auf möglichst einfache Weise bezüglich der Körnung zu verbessern.Procedure for leveling the grain of transparencies. The subject The present invention forms a method to the grain or the other To remove defects in transparent or semi-transparent bodies. In particular the present method is used to transfer paper, canvas or similar materials, as used in tapes or strips for photographic purposes the simplest possible way to improve the grain size.

Das Verfahren besteht im wesentlichen darin, daß man die mit einer lichtempfindlichen Schicht auf einer Seite überzogenen Unterlagen von der anderen Seite aus, die nicht empfindlich gemacht worden ist, belichtet, so daß das Licht die transparenten Materialien durchdringt. Auf diese Weise wird die lichtempfindliche Schicht an den durchscheinenden Stellen mehr exponiert als, an den weniger durchscheinenderen Stellen. Bei der nachfolgenden Behandlung wird die Entwicklung und Fixierung so rechtzeitig unterbrochen, daß eine vollständig gleichmäßige Durchsicht entsteht.The process consists essentially in the fact that one with a photosensitive layer on one side coated documents from the other Side out that has not been made sensitive, exposed so that the light penetrates the transparent materials. This way it becomes light sensitive Layer more exposed in the translucent areas than in the less translucent areas Place. In the subsequent treatment, the development and fixation will be like this interrupted in time that a completely uniform view is created.
