Description

Doppelseitig beschichtetes Kopiermaterial für Farbenphotographie Bei der Herstellung von Farbenfilmen, bei denen die Teilfarbenbilder -in verschiedenen Schichten übereinanderliegen, ist es meistens schwierig, die Ursache von Fehlern in der Farbwiedergabe mit Sicherheit in kurzer Zeit festzustellen.Double-sided coated copy material for color photography In the production of color films in which the partial color images - are superimposed in different layers, it is usually difficult to determine the cause of errors in the color reproduction with certainty in a short time.

Erfindungsgemäß wird dieser Übelstand dadurch beseitigt, daß man das Kopiermaterial bei der Fabrikation bereits mit einer Kennzeichnung versieht,. die es ermöglicht, leicht und rasch festzustellen, ob etwaige Fehler durch falsche Belichtung oder während der nachfolgenden Behandlung der Schichten, insbesondere in den Farbbädern, entstanden sind. Zu diesem Zweck wird das - Kopiermaterial am Ende des Herstellungsprozesses zweckmäßig _ beim Perforieren außerhalb der Bildfläche an übereinanderliegenden Stellen der lichtempfindlichen Schichten von beiden Seiten intermittierend mit Licht bestimmter Intensität vorbelichtet. Man erhält so fortlaufend auf dem Film kleine Felder, die nach der Entwicklung eine bestimmte Schwärzung zeigen und die nachher durch ordnungsmäßig angewandte Farbbäder in einen bestimmten Farbton übergeführt werden. Verwendet man beispielsweise einen Zweifarbenfilm, so zeigen die belichteten Felder durch Übereinander-Lagerung des Blaugrünbildes und des Orangebildes in der Durchsicht einen grauen Farbton.According to the invention, this drawback is eliminated by the Copy material already provided with a label during manufacture. the it enables you to quickly and easily determine whether any errors due to incorrect exposure are present or during the subsequent treatment of the layers, especially in the dye baths, have arisen. For this purpose, the copy material is used at the end of the manufacturing process expedient _ when perforating outside the image area on one on top of the other Exposing the photosensitive layers from both sides intermittently with light pre-exposed to a certain intensity. So you get small ones continuously on the film Fields that show a certain darkness after development and that afterwards converted into a certain shade by properly applied dye baths will. For example, if a two-color film is used, the exposed ones show Fields by superimposing the blue-green image and the orange image in the Look through a gray shade.

Zweckmäßig werden die belichteten Felder in übereinanderliegenden Schichten so angebracht, daß sie sich nicht. vollkommen decken, so daß man an den nicht deckenden Stellen die Einzelfärbung der Schichten prüfen kann.The exposed fields are expediently located one on top of the other Layers attached so that they do not move. completely cover, so that you can get to the check the individual color of the layers in areas that are not opaque.

Durch Belichtung mit gleichmäßig abnehmenden Intensitäten kann man auch eine Reihe von Feldern mit abgestufter Schwärzung herstellen. Das Auftreten der Standardfärbung bzw. des neutralen Grautones oder des Grauleiters auf dem fertigen Film be-.weist ohne weitere Versuche sofort die richtige Entwicklung und Färbung der Schichten. Eine falsche Farbwiedergabe der Bilder kann demnach in diesem Fall nur auf fehlerhafte Kopierbelichtung zurückgeführt werden.By exposure to evenly decreasing intensities, one can also create a series of fields with graduated blackening. The appearance the standard color or the neutral shade of gray or the gray scale on the finished The film immediately proves the correct development and coloring without further attempts of the layers. A wrong color reproduction of the pictures can therefore in this case can only be attributed to incorrect copy exposure.
