Abstract

The method involves an offset printing plate being produced on transparent paper. It is fitted on an assembly arch, and it is subsequently illuminated with UV. The picture or text to be printed is applied by means of a laser printer in positive form, the laser moving laterally, pref. under computer control. USE - To produce an offset printing plate.

Description

Die Erfindung bezieht sich auf ein Verfahren zur Herstel­ lung einer Offset-Druckplatte durch Montage von Platten­ kopiervorlagen auf einen zur Auflage auf eine Offset- Druckplatte bestimmten Montagebogen und anschließender Belichtung der Offset-Druckplatte.The invention relates to a method of manufacture an offset printing plate by mounting plates templates on a to be placed on an offset Pressure plate specific assembly sheet and subsequent Exposure of the offset printing plate.

Die Herstellung von Offset-Druckplatten erfolgt derzeit dadurch, daß man zunächst auf weißem Papier möglichst gu­ te Reprovorlagen erzeugt und diese dann abfotografiert. Den auf diese Weise erzeugten Positivfilm oder bei gerin­ geren Qualitätsanforderungen Negativfilm montiert man als Vorlage auf eine Druckplatte, die anschließend mit UV-Licht belichtet und nach Entfernen der Vorlagen ent­ wickelt wird. Die Druckplatte wird später zum Drucken in die Offset-Druckmaschine eingespannt.Offset printing plates are currently being manufactured by first gu as possible on white paper generated repro templates and then photographed them. The positive film produced in this way or at low stricter quality requirements as a template on a printing plate, which then with Exposed to UV light and removed after removing the originals is wrapped. The printing plate is later used for printing in the offset printing machine clamped.

Das Erzeugen eines Positivfilms oder Negativfilms verur­ sacht beträchtlichen Kostenaufwand und macht die Verwen­ dung von Chemikalien erforderlich, deren Entsorgung wie­ derum teuer ist und zu einer Belastung der Umwelt führt.Create a positive film or negative film lowers considerable costs and makes use of chemicals required, their disposal such as which is expensive and leads to pollution of the environment.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren der eingangs genannten Art zu entwickeln, bei dem das Er­ zeugen eines Positivfilms oder Negativfilms auf fotogra­ fischem Wege unnötig ist, welches aber dennoch einen sau­ beren, konturenscharfen Druck ermöglicht.The invention has for its object a method to develop the type mentioned in which the Er testify to a positive or negative film on fotogra fishing is unnecessary, but which is still a mess beren, contour-sharp printing enables.

Diese Aufgabe wird auf überraschend einfache Weise da­ durch gelöst, daß die Plattenkopiervorlagen aus Transpa­ rentpapier bestehen und die zu druckenden Abbildungen oder die Texte seitenverkehrt in Positivform auf die Plattenkopiervorlagen aufgebracht werden. This task is done in a surprisingly simple way solved by that the plate templates from Transpa Rent paper exist and the images to be printed or the texts are reversed in positive form on the Plate copy templates are applied.  

Durch diese Verfahrensweise kann man auf das kosteninten­ sive und umweltbelastende Herstellen von Filmen verzich­ ten und die auf Transparentpapier erzeugten Plattenko­ piervorlagen unmittelbar auf den Druckbogen für die Off­ set-Druckplatte montieren. Das Transparentpapier eignet sich hervorragend als Plattenkopiervorlage. Da es wie ei­ ne Streufolie wirkt, werden beim Kontaktbelichten der Druckplatte keine Kanten der Vorlagen sichtbar. Für UV- Licht, mit welchem man die Druckplatten belichtet, ist Transparentpapier gut durchlässig. Die erforderliche Be­ lichtungszeit der Offset-Druckplatte wird gegenüber her­ kömmlichen Verfahren auf 30% reduziert. Das führt zu ei­ ner erheblichen Verlängerung der Lebensdauer der Belich­ tungslampe und zu einer Energieeinsparung.By doing this, you can cut costs sive and environmentally harmful production of films waive ten and the Plattenko produced on tracing paper pier templates directly onto the printing sheet for the off Mount the set pressure plate. The tracing paper is suitable is excellent as a plate copy template. Since it's like an egg ne diffusion film is effective when contact exposure of the Printing plate no edges of the templates visible. For UV Light with which the printing plates are exposed is Transparent paper well permeable. The required loading the clearing time of the offset printing plate is compared conventional procedures reduced to 30%. That leads to egg A significant increase in the life of the Belich lamp and for energy saving.

Das erfindungsgemäße Verfahren erlaubt die Herstellung von Druckplatten mit einem im Vergleich zum Stand der Technik ganz wesentlich geringerem Kostenaufwand, führt jedoch zu keiner von Laien feststellbaren Verschlechte­ rung der Druckqualität.The method according to the invention allows production of printing plates with a compared to the state of the Technology significantly lower costs however, no deterioration ascertainable by laypeople print quality.

Bei dem Transparentpapier kann es sich um handelsüblich­ es Transparentpapier handeln, welches beispielsweise als Zeichenpapier benutzt wird. Um sich möglichst gut elek­ trisch aufzuladen, sollte das Transparentpapier mög­ lichst dünn sein.The tracing paper can be commercially available it is tracing paper, which for example as Drawing paper is used. In order to be as good as possible the transparent paper should be possible be as thin as possible.

Das erfindungsgemäße Verfahren kann auch in Kombination mit dem bisherigen Verfahren angewandt werden, indem bei­ spielsweise die zu druckenden Texte erfindungsgemäß auf Transparentpapier als Vorlage geschrieben und zu drucken­ de Bilder wie bisher als Film auf den Montagebogen mon­ tiert werden. The method according to the invention can also be used in combination can be used with the previous method by for example, the texts to be printed according to the invention Tracing paper written as a template and print de Pictures as before as a film on the assembly sheet mon be animals.  

Die einzelnen Vorlagen können sehr rasch seitenverkehrt beschriftet werden, wenn der zu druckende Text mittels eines Laserdruckers seitenverkehrt auf das Transparent­ papier geschrieben wird. Ein solches Beschriften berei­ tet einem von einem Computer gesteuerten Laserdrucker keine Schwierigkeiten, so daß die erfindungsgemäßen Plat­ tenkopiervorlagen gleich schnell oder noch schneller wie übliche Vorlagen ausgedruckt werden können.The individual templates can be reversed very quickly be labeled if the text to be printed is printed using of a laser printer reversed on the transparency paper is written. Such labeling is needed a laser printer controlled by a computer no difficulties, so that the plat Copy templates as quickly or even faster as usual templates can be printed out.
