  Verfahren zur Herstellung von   Tiefdruckmontageformen.   



   Verfahren zur Herstellung von Tiefdruckmontageformen, die ein gleichzeitiges Übertragen und Ätzen von Bild und Schrift ermöglichen, sind bekannt, haben sich aber in der Praxis nicht einbürgern können. 



   Das Vertahren Patent Nr. 318686 z. B. hat deshalb zu praktischen Erfolgen nicht geführt, weil seine   Umständlichkeit-Rändern   der Diapositive mit Lack, Einfärben der Schicht oder Autbringen einer neuen Schicht, Entfernen des Lacks und   Trocknen-den durch gleichzeitiges Übertragen   und Ätzen erzielten Zeitgewinn zunichte macht.

   Zudem muss bereits bei Herstellung der Negative auf genaue   Bildbegrenzung Rücksicht   genommen werden, was insbesondere bei komplizierten Bildüberschneidungen Schwierigkeiten und Zeitverlust bedingt und ein Einsetzen von Bildern in der letzten Minute, wie es der moderen Zeitschriftenbetrieb erfordert, unmöglich macht.   Schliesslich   ist ein sicherer Erfolg mit dem Verfahren deshalb nicht zu erwarten, weil einmal ein völlig gleichmässiges Einfärben der Bildschicht oder gar einer aufgegossenen Schicht nicht immer möglich ist und anderseits die photographische Herstellung der Schrift zusammen mit den Diapositiven zu ungleichmässigen Ergebnissen führt. 



   Diese Mängel sucht das nachstehend beschriebene Verfahren zur Herstellung von Tiefdruckmontageformen, die gleichzeitiges Übertragen von Bild und Schrift ermöglichen, abzustellen. Das Verfahren wird folgendermassen ausgeführt :
Zur Verwendung gelangen von vornherein mit einem inaktinischen Farbstoff gefärbte photographische Filme. Gefärbt kann die Schicht selbst oder das Zelluloid oder eine besondere z. B. auf der Rückseite des Films aufgebrachte Schicht sein. Ausreichende Färbung kann beispielsweise oft schon dadurch erzielt werden, dass zur Herstellung der Filme ein besonders gelbes Zelluloid verwendet wird oder dass die Filme auf der Rückseite mit einer ausreichend opaken Retouchemattschicht versehen sind. 



  Auf diesen Filmen werden die Diapositive einzeln oder zu mehreren gemeinsam in ungefähr der endgültigen   Bildgrösse hergestellt   und nach dem Trocknen auf genaue Grösse und Form beschnitten. Darauf werden sie an den Rändern mit ganz wenig eines völlig   lichtdurchlässigen   Klebstoffs an ihren Platz auf der   Montagescheibe   angeheftet. Der Text wird auf bekannte Art auf durchsichtiges Material, beispielsweise Cellophan, gedruckt und zwischen die Bilder eingerückt. 



   Das Ergebnis ist eine Montage, bei der alles ausser Text und Bild selbst völlig gleichmässig lichtdurchlässig ist und in die auch im letzten Augenblick noch Bilder und Text eingerückt werden können. 



  Das Abdecken auf dem Kupferzylinder ist daher auf ein blosses Zudecken des blanken Kupfers beschränkt, und gemeinsamer Übertrag und Ätzung ist möglich, ohne dass die vorbereitenden Arbeiten der Photographie mehr als die übliche Zeit in Anspruch nehmen. 

**WARNUNG** Ende DESC Feld kannt Anfang CLMS uberlappen**.

  Process for the production of gravure mounting forms.



   Processes for the production of intaglio mounting forms, which allow a simultaneous transfer and etching of image and writing, are known, but have not been able to become naturalized in practice.



   Process Patent No. 318686 e.g. B. has therefore not led to practical success, because its inconvenience - edges of the slides with varnish, coloring the layer or applying a new layer, removing the varnish and drying - destroys the time gained by simultaneous transfer and etching.

   In addition, precise image delimitation must be taken into account when producing the negatives, which causes difficulties and loss of time, especially with complicated overlapping images, and makes it impossible to insert images at the last minute, as is required by modern magazine operations. Ultimately, a certain success with the process cannot be expected because, on the one hand, a completely uniform coloring of the image layer or even a poured layer is not always possible and, on the other hand, the photographic production of the writing together with the slides leads to uneven results.



   The method described below for the production of rotogravure mounting forms which allow the simultaneous transfer of image and writing attempts to remedy these deficiencies. The procedure is carried out as follows:
Photographic films dyed with an inactinic dye from the outset are used. The layer itself or the celluloid or a special z. B. be applied to the back of the film layer. Sufficient coloring can often be achieved, for example, by using a particularly yellow celluloid to produce the films or by providing the films with a sufficiently opaque retouching mat layer on the back.



  On these films, the slides are produced individually or in groups together in approximately the final image size and, after drying, trimmed to the exact size and shape. They are then attached to their place on the mounting disc at the edges with a very small amount of completely translucent glue. The text is printed in a known manner on transparent material such as cellophane and is indented between the images.



   The result is a montage in which everything except text and image is completely evenly translucent and in which images and text can be indented even at the last moment.



  The covering on the copper cylinder is therefore limited to a mere covering of the bare copper, and joint transfer and etching is possible without the preparatory work of photography taking up more than the usual time.
