Abstract

Base film comprises a self-adhering polymer film and has a thickness of 0.04-2.10 mm. An independent claim is also included for a rubber blanket made from the base film.

Description

Die vorliegende Erfindung betrifft eine selbsthaftende Unterlagenfolie für den Offsetdruck.The present invention relates to a self-adhesive backing sheet for offset printing.

Im Offsetdruck werden sowohl auf dem Plattenzylinder als auch auf dem Gummidrucktuchzylinder kalibrierte Unterlagebögen mit und ohne Kleber eingesetzt. Diese dienen dazu, die Umfanglänge der Zylinder der Drucklänge anzupassen. Dies ist nötig, da die Zylinder abhängig vom Druckmaschinenhersteller einen unterschiedlich tiefen Einstich haben und die eingesetzten Druck- und Lackierplatten und Gummidrucktücher unterschiedlich dick sind. Hierzu ist es notwendig, verschieden dicke Papier- oder Kartonbögen oder Unterlagefolien einzusetzen, die diese Unterschiede ausgleichen.In offset printing, calibrated underlay sheets with and without adhesive are used both on the plate cylinder and on the blanket cylinder. These serve to adjust the perimeter length of the cylinders to the print length. This is necessary because the cylinders have a different depth of penetration depending on the printing press manufacturer and the printing and coating plates and blankets are different in thickness. For this purpose, it is necessary to use different thickness paper or cardboard sheets or backing sheets that compensate for these differences.

Sowohl bei den kalibrierten Papier- und Kartonbögen als auch bei den Unterlagenfolien existieren Ausführungen mit und ohne selbstklebende Ausrüstung. Bei automatischem Platteneinzug kommen nur selbstklebende Unterlagefolien zum Einsatz.Both the calibrated paper and cardboard sheets as well as the backing films have versions with and without self-adhesive equipment. With automatic plate feeder only self-adhesive underlay films are used.

Selbstklebende Folien haben den Vorteil, dass sie leichter zu montieren sind, da sie nicht verrutschen können. Nachteilig an den selbstklebenden Unterlagefolien ist jedoch, dass der Wechsel zeitaufwendiger ist, da gegebenenfalls Kleberrückstände von der Zylinderoberfläche entfernt werden müssen. Hierbei ist zu bedenken, dass beispielsweise im Rollenoffset für den Zeitungsdruck durchaus 64 oder auch 128 Druckwerke eingesetzt werden.Self-adhesive films have the advantage that they are easier to assemble because they can not slip. A disadvantage of the self-adhesive underlay films, however, is that the change is more time-consuming, since adhesive residues may have to be removed from the cylinder surface. It should be noted that, for example, in web offset for newspaper printing quite a 64 or 128 printing units are used.

Es besteht daher weiterhin ein Bedarf nach verbesserten Unterlagematerialien, die die genannten Nachteile des Standes der Technik überwinden.Therefore, there remains a need for improved backing materials that overcome the aforementioned disadvantages of the prior art.

Gelöst wird die Aufgabe durch eine Unterlagenfolie für den Offsetdruck umfassend mindestens eine selbsthaftende Polymerfolie, wobei die Unterlagenfolie eine Dicke von 0,04 bis 2,10 mm aufweist.The object is achieved by a backing film for offset printing comprising at least one self-adhesive polymer film, wherein the backing film has a thickness of 0.04 to 2.10 mm.

Statt einer selbstklebenden Ausrüstung der kalibrierten Unterlagefolie werden solche eingesetzt, die selbsthaftende Eigenschaften aufweisen. Diese weisen aufgrund ihrer spezifischen, zumindest einseitig weichen Oberfläche gute Haftwerte gegenüber den glatten Zylinderoberflächen auf. Der sogenannte "Glasplatteneffekt" verhindert ein Verschieben auch bei hoher Druckgeschwindigkeit und höheren Temperaturen, bei denen selbstklebende Folien teilweise ihre Scherfestigkeit verlieren.Instead of self-adhesive equipment of the calibrated backing film, those are used which have self-adhesive properties. Due to their specific, at least unilaterally soft surface, these have good adhesion values compared with the smooth cylinder surfaces. The so-called "glass plate effect" prevents displacement even at high printing speeds and higher temperatures, in which self-adhesive films lose some of their shear strength.

Da es sich erfindungsgemäß um ein kleberloses System handelt, können auch keine Rückstände auf den Zylinder verbleiben. Dies erspart eine zeitaufwendige Reinigung und beschleunigt damit den Wechsel der Unterlagen.Since it is a glueless system according to the invention, no residues can remain on the cylinder. This saves a time-consuming cleaning and thus accelerates the change of documents.

Gute selbsthaftende Eigenschaften können beispielsweise mit einem 180° Abzugstest mit einer Abzugsgeschwindigkeit von 300 mm/min erreicht werden. Hierbei liegen besonders geeignete Werte für die selbsthaftende Folie im Bereich von 3 bis 8 N/25 mm.Good self-adhesive properties can be achieved, for example, with a 180 ° peel test with a take-off speed of 300 mm / min. Here are particularly suitable values for the self-adhesive film in the range of 3 to 8 N / 25 mm.

Geeignete Materialen für die Herstellung von selbsthaftenden Polymerfolien sind dem Fachmann grundsätzlich bekannt. Besonders geeignete Materialien werden ausgewählt aus der Gruppe Weich-PVC, Polyurethan, Polyethylen, Polypropylen, Ethylvinylacetat und Mischungen hiervon.Suitable materials for the production of self-adhesive polymer films are known to those skilled in principle. Particularly suitable materials are selected from the group of soft PVC, polyurethane, polyethylene, polypropylene, ethyl vinyl acetate and mixtures thereof.

In einer Ausführungsform kann die selbsthaftende Schicht mit einer nichthaftenden Folie kombiniert werden. Die nichthaftende Kunststofffolie verhindert das Verkleben mit der darüber liegenden Offsetplatte.In one embodiment, the pressure-sensitive layer may be combined with a non-adhesive film. The non-adhesive plastic film prevents sticking to the overlying offset plate.

Geeignete Materialien für die nichthaftende Kunststofffolie sind Polyethylen-Terephthalat, Polyurethan, PVC, Polyethylen, Polypropylen und Mischungen hiervon.Suitable materials for the non-adhesive plastic film are polyethylene terephthalate, polyurethane, PVC, polyethylene, polypropylene and mixtures thereof.

In einer bevorzugten Ausführungsform kann die nichthaftende Kunststofffolie eine Rückseitenmattierung aufweisen. Bei Rollen-Offset-Maschinen wird diese unter dem Gummituch platziert und verhindert das Rutschen des Tuches auf der sonst glatten Folienrückseite.In a preferred embodiment, the non-adhesive plastic film may have backside matting. For roll offset presses this becomes placed under the blanket and prevents slipping of the cloth on the otherwise smooth foil back.

In einer weiteren Ausführungsform ist die selbsthaftende Polymerfolie mit einem Gummidrucktuch laminiert. Es entsteht so ein selbsthaftendes Gummidrucktuch, das in besonders einfacher und komfortabler Weise montiert werden kann.In another embodiment, the pressure-sensitive polymer film is laminated with a rubber blanket. The result is a self-adhesive rubber blanket that can be mounted in a particularly simple and comfortable way.
