Description

Die Erfindung betrifft eine Vorrichtung, die ermöglicht, von photographischen Negativen auf in bekannter Weise lichtempfindlich gemachten zylinderförmigen Druckwalzen direkt zu kopieren, so daß bei dem zwei- oder mehrfarbigen Druck ein genaues Passen (Registerhalten) gewährleistet ist.The invention relates to a device that enables photographic negatives directly on cylindrical pressure rollers made photosensitive in a known manner to be copied, so that an exact fit (register keeping) in the case of two-color or multi-color printing is guaranteed.

Bei den derzeitigen Methoden des Aufbringens der verschiedenen Teilbilder auf einzelneWith the current methods of applying the various partial images to individual

ίο zylinderförmige Druckwalzen 2 besteht die Schwierigkeit darin, daß die Teilbilder der einzelnen Druckzylinder nicht symmetrisch genau zueinander stehen, und da ein Einpassen bei den dieses Druckmaterial verarbeitenden Maschinen fast unmöglich ist, so muß das Teilbild auf jedem Zylinder an haargenau derselben Stelle sich von vornherein befinden.ίο cylindrical pressure rollers 2 consists of the Difficulty is that the partial images of the individual printing cylinders are not symmetrically accurate are related to each other, and there is a fitting in those who process this printing material Machines is almost impossible, so the drawing file on each cylinder must be exactly the same Right from the start.

Bei Verwendung der Spannkluppe 1 nach der Erfindung werden die Teilnegative 3, die mit entsprechenden Paßkreuzen versehen sind, in die für die letzteren vorgesehenen Einschnitte 4 der Spannkluppe 1 eingesetzt und justiert.When using the clamp 1 according to the invention, the partial negatives 3, the are provided with corresponding register marks in the notches provided for the latter 4 of the clamp 1 inserted and adjusted.

Der auf Konen ruhende lichtempfindlich gemachte Druckzylinder wird nun mit dem zwischen beiden Spannkluppenteilen 1 befestigten Photonegativ 3 durch Vereinigen der beiden Kluppenteile 1 umspannt und seitlich in der Axiakichtung befestigt.The light-sensitive printing cylinder resting on cones is now with the between two clamping clamp parts 1 attached photographic negative 3 by combining the two Clamp parts 1 spanned and fastened laterally in the axial seal.

Dadurch, daß die Spannkluppe 1 nur einseitig gelöst zu werden braucht und das Einbringen jedes weiteren Teilnegativs 3 nunmehr zwangsläufig durch die durchstochenen Paßkreuze erfolgt, ist ein genaues Passen gewährleistet. The fact that the clamping clip 1 only needs to be released on one side and the introduction every further partial negative 3 now inevitably through the pierced register crosses takes place, an exact fit is guaranteed.

Im Vergleich zu den derartigen Vorrichtungen, wo ein Überdecken von Bildteilen stattfindet, bezweckt die Maulform der Spannkluppe i, daß alle im Negativ 3 lichtdurchlässigen Stellen bis auf den ganz geringen etwa ι mm breiten von der Spannkluppe 1 gebildeten Schatten vom Licht passiert werden können.Compared to such devices, where a covering of image parts takes place, The purpose of the mouth shape of the clamping clip i is that all in the negative 3 are translucent Set up to the very small approximately ι mm wide of the clamping clip 1 formed shadows can be passed by the light.
