Abstract

1. A process for the production of an offset printing plate by transferring information onto a printing suitable for offset printing, wherein one or more vaporizable and/or fusible substances of the formula (I) A-Xn wherein A is an n-valent hydrophobic radical, X is a hydraulic substituent and n is 1, 2, 3 or 4 are transferred imagewise from a base onto the printing plate by means of an electronically controlled thermal head.

Description

Die Übertragung von Information auf eine Offsetdruckplatte geschieht nach dem Stand der Technik beispielsweise mittels photofrthographischer Verfahren.According to the prior art, information is transferred to an offset printing plate, for example by means of photofrthographic methods.

Dazu muß von der Vortage eine geeignete Maske z.B auf photographischem Weg erzeugt werden. Eine lichtempfindlich beschichtete Druckplatte kann durch Belichten durch diese Maske bildmäßig in hydrophobe und hydrophile Bereiche differenziert werden.For this, a suitable mask must be created from the previous day, e.g. by photographic means. A light-sensitive coated printing plate can be imagewise differentiated into hydrophobic and hydrophilic areas by exposure through this mask.

Eine weitere Möglichkeit der Informationsübertragung auf eine für den Offsetdruck geeignete Druckplatte besteht in der elektrophotographischen Arbeitsweise.Another possibility of transferring information to a printing plate suitable for offset printing is the electrophotographic method.

Der Erfindung lag die Aufgabe zugrunde, ein Verfahren zur Herstellung von Offsetdruckplatten bereitzustellen, bei dem elektrisch gespeicherte Informationen, wie Texte oder auch Bilder, direkt, d.h. ohne ein optisches Zwischenbild, wie dies z.B. in der photographischen Arbeitsweise nötig ist, auf eine für den Offsetdruck geeignete Druckplatte übertragen werden können.The invention was based on the object of providing a method for producing offset printing plates in which electrically stored information, such as texts or images, is direct, i.e. without an intermediate optical image, such as e.g. in the photographic mode of operation is necessary, can be transferred to a printing plate suitable for offset printing.

Die vorher hydrophile Plattenoberfläche wird durch (I) an den Übertragungstellen hydrophobiertThe previously hydrophilic plate surface is made hydrophobic by (I) at the transfer sites

Das erfindungsgemäße Verfahren hat gegenüber den Verfahren des Standes der Technik eine Reihe von Vorteilen:

  • a) man kann unbeschichtete Druckplatten verwenden;
  • b) die photomechanischen Schritte zur Übertragung der Information (in Form von Schrift oder Bifdem) auf eine Offsetplatte und zwar sowohl bei Offsetplatten für Schwarz-Weiß-, als auch bei solchen für den Mehrfarbendruck entfällt;
  • c) eine Bildvortage ist in der Regel nicht erforderlich, weshalb das Verfahren besonders geeignet ist, elektronisch gespeicherte Informationen auf eine Offsetplatte zu übertragen;
  • d) bei Verwendung farbiger Verbindungen (I) ist die übertragene Information sichtbar;
  • e) das Entwickeln der Platte mit bestimmten Lösungsmitteln (photolithographisches Verfahren) oder das Betonem und Einbrennen des Toners (elektrophotographisches Verfahren) entfällt.
The method according to the invention has a number of advantages over the methods of the prior art:
  • a) you can use uncoated printing plates;
  • b) the photomechanical steps for transferring the information (in the form of writing or bifdem) to an offset plate, specifically in the case of offset plates for black and white as well as those for multi-color printing, are omitted;
  • c) An image presentation is generally not necessary, which is why the method is particularly suitable for transferring electronically stored information to an offset plate;
  • d) when using colored compounds (I) the transmitted information is visible;
  • e) there is no need to develop the plate with certain solvents (photolithographic process) or to emphasize and burn in the toner (electrophotographic process).
