  Verfahren zur Herstellung von   Naturfarbenfilms.   
 EMI1.1 
 in den erwähnten   Kopier-und Korrekturapparat   gegeben wird, so kann man unter Vorschaltung der entsprechenden Filter auf drei gesonderten Filmstreifen drei rasterlose Negative erhalten, deren Farbwerte verschieden sind, wodurch die Möglichkeit gegeben ist, mit dem Apparat nach Patent Nr. 102743 Kopien beliebiger Anzahl herzustellen, wodurch der Rasterpositivfilm zur Gänze in einen rasterlosen Negativfilm umgewandelt wird. 



   In der Zeichnung ist eine beispielsweise Ausführung des Kopier-und Korrekturapparates dargestellt, u. zw. zeigt Fig. 1 einen Grundriss der Anordnung der Teilapparate unter einem Winkel von   90 ,   während Fig. 2 den Strahlengang bei Durchgang der Lichtstrahlen durch das Prisma und Objektiv veranschaulich. 



   Es wird angestrebt, die Bilderreihe am Positivband genau so gerichtet zu erhalten wie am Negativband. Dies wird auf zwei Arten erreicht u. zw. dadurch, dass man entweder das einfache Objektiv des Kopier-und Korrekturapparates durch ein Doppelobjektiv ersetzt oder durch Anordnung der beiden Teilapparate   1,   2 (Fig. 1) unter einem Winkel von 900 und Einschaltung eines Prismas in den Strahlengang. Sowohl durch die erstere als auch durch die letztere Art wird eine Umkehrung und Wiederaufrichtung des Bildes im Laufe des Strahlenganges erzielt. Den Strahlengang der letzteren Art veranschaulicht Fig. 2, u. zw. zeigt   a-b   ein Bild des Negativfilms, das vom Prisma 3 durch das Objektiv   4   geworfen wird und das Positivbild a'-b'ergibt. 



   Bei Herstellung des Farbfilms nach vorliegendem Verfahren mit mehreren Emulsionsschichten empfiehlt es sich, in gewissen Abständen, die mit einem Lochapparat des genannten Kopierapparates

  Wenn dies aber nicht der Fall ist, so können notwendige Korrekturen ohne weiteres mit Hilfe der Feineinstellungsvorriehtungen vorgenommen werden. Dieser Vorgang muss dann erfolgen, wenn beim Durchlaufen des mit der ersten Bilderreihe versehenen Films bei stetiger Kontrolle sich Ungenauigkeiten eingestellt hätten. Der Vorteil eines derartigen kontrollierbaren Kopierverfahrens besteht noch darin, dass die im Negativ nicht richtig exponierten Stellen während des Kopierens auf dem Positivfilm korrigiert werden können, u. zw. dadurch, dass man die Lichtquelle je nach Bedarf   mittels Regulierungswiderstandes   mehr oder weniger intensifiziert oder aber die Geschwindigkeit des antreibenden Motors für die gewünschte Belichtungszeit reguliert.

  Process for the production of natural color film.
 EMI1.1
 is placed in the above-mentioned copier and correction apparatus, then with the appropriate filters on three separate film strips, three screenless negatives can be obtained, the color values of which are different, which makes it possible to produce any number of copies with the apparatus according to Patent No. 102743 whereby the screen positive film is entirely converted into screenless negative film.



   In the drawing, an example of an embodiment of the copier and correction apparatus is shown, u. FIG. 1 shows a plan view of the arrangement of the sub-apparatus at an angle of 90, while FIG. 2 illustrates the beam path when the light rays pass through the prism and lens.



   The aim is to keep the series of images on the positive tape in the same direction as on the negative tape. This is accomplished in two ways: by either replacing the simple objective of the copying and correction apparatus with a double objective or by arranging the two sub-apparatuses 1, 2 (FIG. 1) at an angle of 900 and inserting a prism in the beam path. Both the former and the latter type achieve an inversion and realignment of the image in the course of the beam path. The beam path of the latter type is illustrated in FIG. 2, u. between a-b shows an image of the negative film which is thrown from the prism 3 through the objective 4 and which gives the positive image a'-b '.



   When producing the color film according to the present process with several emulsion layers, it is advisable to use a punching device of the copier mentioned at certain intervals
 EMI1.2
 



  If this is not the case, the necessary corrections can easily be made with the aid of the fine adjustment devices. This process must take place if inaccuracies would have arisen when the film provided with the first row of images had run through with constant monitoring. The advantage of such a controllable copying process is that the areas that are not correctly exposed in the negative can be corrected during copying on the positive film, and the like. between the fact that the light source is intensified to a greater or lesser extent as required by means of a regulating resistor, or the speed of the driving motor is regulated for the desired exposure time.
