Description

Um von einem bestehenden Satz, Klischee, Lithographie od. dgl., transparente Durchsichtsbilder herzustellen, z. B. Durchsichtspositive, welche als Kopiervorlagen für den Offset- und Tiefdruck dienen, hat man bisher z. B. den Satz auf eine transparente Folie gedruckt und den Druck zur Erhöhung der Deckung eingestaubt.To use an existing sentence, cliché, lithography or the like, transparent see-through images to manufacture, e.g. B. See-through positives, which can be used as templates for offset and gravure printing serve, one has so far z. B. printed the sentence on a transparent film and the pressure to increase dusty of the cover.

Außerdem bediente man sich lichtempfindlicher Schichten, auf welche der Satz durch Licht mit ίο oder ohne Optik übertragen wurde. Um zu einem guten Endresultat zu gelangen, ist ein guter Abdruck der betreffenden Druckform Voraussetzung.In addition, light-sensitive layers were used, onto which the sentence was translated by light ίο or was transmitted without optics. To get a good bottom line, there is a good footprint the relevant printing form is a prerequisite.

Es hat sich gezeigt, daß der Druck auf transparente Folien nur sehr mangelhafte Resultate ergibt; er hat aus diesem Grunde in die Praxis keinen Eingang finden können.It has been shown that printing on transparent films gives only very poor results; for this reason it has not found its way into practice.

Demgegenüber stellt sich die vorliegende Erfindung die Aufgabe, transparente Folien herzustellen, mittels welcher man durch Aufdrucken Durchsichtspositive von besserer Deckkraft und Randschärfe als bisher herstellen kann. Dieselben können dann als Kopiervorlagen für den Offset- und Tiefdruck dienen, oder andere Verwendung finden.In contrast, the present invention has the task of producing transparent films, by means of which one can print see-through positives with better opacity and edge definition than before. These can then be used as templates for the offset and Serve gravure, or find other uses.

Die Aufgabe wird dadurch gelöst, daß das zur Bildaufnahme bestimmte Material mit einem Überzug aus transparentem Kautschuk versehen ist, der mindestens an seiner Oberfläche die Eigenschaft aufweist, die Druckfarbe gut anzunehmen.The object is achieved in that the material intended for image recording is provided with a coating made of transparent rubber, which at least on its surface has the property has to accept the printing ink well.

Die Figuren zeigen ein Ausführungsbeispiel der Erfindung. Die Figuren sind im Querschnitt und stark vergrößert gezeichnet.The figures show an embodiment of the invention. The figures are in cross section and drawn greatly enlarged.

In den Figuren bedeutet a) eine Letter, b) die auf die Letter aufgetragene Druckfarbe, c) einen transparenten Schichtträger, z. B. einen Film, d) den erfindungsgemäßen elastischen Belag, der in beliebiger Weise (Streichen, Walzen, Gießen u. dgl.) aufgebracht ist.In the figures, a) means a letter, b) means the printing ink applied to the letter, c) means one transparent support, e.g. B. a film, d) the elastic covering according to the invention, which in Any way (brushing, rolling, pouring and the like) is applied.

Fig. ι und 2 zeigen den bisher üblichen Druckvorgang auf gewöhnliches transparentes Material. Da transparente Folien immer glatte, die Druckfarbe nicht aufsaugende Körper sind, wird die Druckfarbe beim Druckvorgang seitlich bei b (Fig. 2) herausgedrückt. Das Ergebnis ist ein verbreitertes Schriftbild, wobei die einzelnen Buchstäben, insbesondere unmittelbar neben den herausgedrückten Farben, unbedruckte bzw. ungedeckte Stellen e aufweisen (Fig. 3).Fig. Ι and 2 show the usual printing process on ordinary transparent material. Since transparent foils are always smooth bodies that do not absorb the printing ink, the printing ink is pressed out laterally at b (FIG. 2) during the printing process. The result is a widened typeface, with the individual letters, in particular immediately next to the pressed out colors, having unprinted or uncovered areas e (FIG. 3).

Dieses Übel kann auch nicht beseitigt werden durch das Auftragen von nur wenig Druckfarbe,Nor can this evil be eliminated by applying only a little ink,

da sonst die erforderliche Deckung für Kopierzwecke nicht erreicht wird.otherwise the required coverage for copying purposes will not be achieved.

Fig. 4 bis 6 zeigen den Druckvorgang auf eine erfindungsgemäße transparente Folie mit elastischem Belag. Die Druckfarbe wird dabei in den elastischen Belag d hineingedrückt; der elastische Belag unterhalb der Letter weicht nach der Seite aus und bildet neben der Letter Erhebungen e (Fig. 5), welche das seitliche Herausdrücken der Farbe praktisch genügend stark verhindern. Die punktierten Linien f in Fig. 2 und 3 zeigen die Schriftverbreiterung bei dem bisher üblichen Druckgang. Hingegen wird erfindungsgemäß nach dem Drucken der elastische Belag wieder frei von Belastung und geht samt dem Aufdruck auf die Ursprungsbreite zurück (Linie / in den Fig. 5 und 6).4 to 6 show the printing process on a transparent film according to the invention with an elastic covering. The printing ink is pressed into the elastic covering d ; the elastic covering below the letter gives way to the side and forms next to the letter elevations e (Fig. 5), which practically prevent the lateral pressing out of the color sufficiently strong. The dotted lines f in FIGS. 2 and 3 show the widening of the font in the previously usual printing process. In contrast, according to the invention, after printing, the elastic covering is again free of stress and goes back to the original width together with the printing (line / in FIGS. 5 and 6).

Das Ergebnis ist ein originalgetreues Durchsichtspositiv, welches an allen bedruckten Stellen eine scharf begrenzte, kopierfähige Deckung aufweist. The result is a true-to-original see-through positive, which is used in all printed areas has a sharply defined, copyable cover.

Als Schichtträger können z. B. transparente Filme aus Cellulosenitrat, Celluloseacetat, Zellglas od. dgl. Kunststoffolien verwendet werden. Der elastische Überzug besteht aus Kautschuk.As a substrate can, for. B. transparent films made of cellulose nitrate, cellulose acetate, cell glass Od. Like. Plastic films can be used. The elastic cover is made of rubber.

Um die Oberfläche des erfindungsgemäßen Belages für die Druckfarbe besser empfänglich zu machen, wird auf sie z.B. Magnesia, Talkum, feinstgeschlämmtes Glaspulver, Bariumsulfat od. dgl. dünn aufgetragen, so daß die Transparenz nicht oder nur wenig geschwächt wird.To make the surface of the coating according to the invention more receptive to the printing ink To make them, e.g. magnesia, talc, finely slurried glass powder, barium sulfate or the like. Applied thinly so that the transparency is not or only slightly weakened.
