Verfahren zur Herstellung von Zurichtungen.
Das bekannte Verfahren der mechanischen Kreidereliefzurichtung beruht im wesentlichen darin, dass eine auf beiden Seiten mit Kreideaufstrichmasse versehene, aus Papierstoff od. dgl. bestehende Unterlage, Folie genannt, auf beiden Seiten bedruckt und auf beiden Seiten geätzt wird. Die Herstellung solcher zweiseitig gestrichener Folien ist schwierig und deshalb teuer. Ausserdem ist die Anwendung derselben deshalb nicht einfach, weil das Bild auf beide Seiten der Folie gedruckt werden muss und die Folie unverwendbar wird, wenn beide Drucke nicht ganz genau aufeinanderpassen.
Es ist nun bereits vorgeschlagen worden, die Folie einseitig nur mit Kreide oder Tonaufstrichmasse zu versehen, wodurch nicht nur die eben erwähnten Nachteile vermieden werden würden, sondern auch eine schwächere Zurichtung erzeugt werden würde, die insbesondere für kräftiger gebaute Zylinderrotations-oder Tiegel-
EMI1.1
dringt, dieselbe angreift und zerstört.
Diesen Nachteil zu beheben, ist das Ziel der vorliegenden Erfindung.
Dieselbe besteht im wesentlichen darin, dass bei derartig einseitig mit feiner Kreide oder Tonmasse belegten Folien die Rückseite durch Imprägnierung oder einen Sehutzaufstrich gegen die Wirkung der Lösung oder Ätzflüssigkeit geschützt wird. Dieser kann beispielsweise aus einem Härtungsmittel, wie Formaldehyd, einem anorganischen Härtesalz od. dgl. mit Tierleim oder Casein als Bindemittel bestehen.
Durch diese Behandlung der Rückseite der Folie wird überdies das Rollen der Folie verhindert ; ausserdem schliesst sie jede Passdifferenz der letzteren aus.

Process for making dressings.
The known method of mechanical chalk relief finishing is essentially based on the fact that a base made of paper or the like and made of paper or the like, provided with chalk on both sides, is printed on both sides and etched on both sides. The production of such double-sided coated films is difficult and therefore expensive. In addition, the same is not easy to use because the image has to be printed on both sides of the film and the film becomes unusable if the two prints do not exactly match one another.
It has already been proposed to provide the film on one side only with chalk or clay, which would not only avoid the disadvantages just mentioned, but would also produce a weaker finish, which is particularly useful for more powerfully built cylinder rotation or crucible
EMI1.1
penetrates, attacks and destroys it.
The aim of the present invention is to remedy this disadvantage.
This essentially consists in the fact that in the case of such foils covered on one side with fine chalk or clay, the back is protected against the effect of the solution or etching liquid by impregnation or a protective coat. This can for example consist of a hardening agent such as formaldehyde, an inorganic hardening salt or the like with animal glue or casein as a binder.
This treatment of the back of the film also prevents the film from rolling; In addition, it excludes any passport difference between the latter.
