Abstract
Description
Die Erfindung betrifft eine Druckplatte nach dem Oberbegriff des 1. Anspruchs.The The invention relates to a printing plate according to the preamble of FIG. 1. Claim.
Um derartige Druckplatten vor Fingerabdrücken, Korrosion und gegen mechanische Einwirkungen, wie Kratzer beim Einspannen der Druckplatte in die Druckmaschine zu schützen, werden die Druckplatten in der Regel einer Gummierung unterzogen. Die Gummierung vor der Lagerung der Platte oder vor langen Stillständen der Druckmaschine gewährleistet auch, dass das Druckbild erhalten bleibt und die bildtragenden Bereiche ihre Eigenschaften nicht verlieren. Gummierungslösungen sind seit langem bekannt und basieren meist auf Gummiarabikum.Around Such printing plates from fingerprints, corrosion and against mechanical influences, such as scratches when clamping the To protect printing plate in the printing press, the Printing plates are usually subjected to a rubber coating. The gum before storage of the plate or long standstill The printing press also ensures that the printed image preserves and the image-bearing areas their properties not lose. Gumming solutions have been known for a long time and are mostly based on gum arabic.
Die Druckplatten werden im gummierten Zustand auf die Plattenzylinder der Druckmaschine befestigt. Zum registergerechten Aufspannen sind die Druckplatten mit Registerstanzungen versehen, die mit einer auf dem Plattenzylinder angeordneten, in der Regel aus zwei beabstandeten Pass-Stiften bestehenden Kontrolleinrichtung korrespondieren.The Printing plates are in the rubberized state on the plate cylinder attached to the printing press. For register-oriented clamping are the printing plates provided with register punches, which with a arranged on the plate cylinder, usually two spaced apart Pass-pins correspond to existing control device.
Beim Drucken wird dann die Gummierung durch das im Druckprozess verwendete Feuchtwasser abgewaschen, damit die Bildbereiche sofort Farbe annehmen können.At the The gumming will then print through that used in the printing process Rinse off dampening solution so that the image areas immediately take on color can.

der
Nachteilig ist, dass durch keine dieser Vorrichtungen eine störungssichere Anlage erzielbar ist. Grund dafür ist, dass die Gummierung eine unerwünschte Beschichtung der Kanten der Registerstanzung zur Folge haben kann. Das verhindert den elektrischen Kontakt der kontaktgebenden Teile der Pass- Stifte mit der Druckplatte in diesem Bereich.adversely is that by none of these devices a fail-safe Plant is achievable. Reason is that the gumming an undesirable coating of the edges of the register punching can result. This prevents the electrical contact of the contacting parts of the dowel pins with the pressure plate in this Area.

Es ist die Aufgabe der Erfindung, die Druckplatte so zu gestalten, dass bei deren Aufspannen auf den Plattenzylinder einer Rotationsdruckmaschine der elektrische Kontakt zwischen der Druckplatte und den auf dem Plattenzylinder angeordneten, die korrekte Lage der Druckplatte detektierenden Kontrolleinrichtung gewährleistet wird.It the object of the invention is to design the printing plate in such a way that that in their clamping on the plate cylinder of a rotary printing machine the electrical contact between the pressure plate and the on the Plate cylinder arranged, the correct position of the pressure plate Detecting control device is ensured.
Die Aufgabe wird durch die Merkmale des 1. Anspruchs gelöst.The Task is solved by the features of the first claim.
Die Erfindung wird nachfolgend an Hand eines Ausführungsbeispiels näher beschrieben. Die dazugehörigen Zeichnungen zeigen:The Invention will be described below with reference to an embodiment described in more detail. The accompanying drawings demonstrate:

Die Entwicklung derartiger Stoffe hat erst begonnen, so dass hier noch Potential vorhanden ist.The Development of such substances has just begun, so here still Potential exists.
Die Gummierungslösung kann mit den üblichen, dem Fachmann hinreichend bekannten Methoden aufgebracht werden. Dazu gehören zum Beispiel die üblichen Beschichtungsmethoden, wie Auftrag mit einem Schwamm bei der Handgummierung, mit einer Rakel, mit Abquetschwalzen, durch Aufsprühen oder durch Tauchverfahren.The Gumming solution can with the usual, the expert sufficiently well known methods are applied. This includes For example, the usual coating methods, such as order with a sponge in hand gumming, with a squeegee, with nip rolls, by spraying or by dipping.
