Abstract

The invention relates to a lithographic machine having an inking unit, a damping unit, a lithographic impression cylinder and a blanket cylinder. The inking unit has a screen roller, against which a squeegee rests, and an ink transfer roller arranged between the screen roller and the impression cylinder. The impression cylinder and the ink transfer roller have the same diameter.

Description

FlachdruckmaschineFlat printing machine

Die Erfindung betrifft eine Flachdruckmaschine mit einem Farbwerk, einem Feuchtwerk, einem lithografischen Druckplattenzylinder und einem Gummituchzylinder, wobei das Farbwerk eine Rasterwalze, der eine Rakel anliegt, und eine zwischen der Rasterwalze und dem Druckplattenzylinder angeordnete Farbübertragwalze aufweist, nach Patent .... (Patentanmeldung P 31 41 903.8-45).The invention relates to a planographic printing machine with an inking unit, a dampening unit, a lithographic printing plate cylinder and a blanket cylinder, wherein the inking unit has an anilox roller that rests against a doctor blade, and one between the Has anilox roller and the printing plate cylinder arranged ink transfer roller, according to patent .... (patent application P 31 41 903.8-45).

Es ist Aufgabe der Erfindung, diese Flachdruckmaschine dahingehend weiter zu verbessern, daß das Schablonieren noch weiter reduziert bzw. vollständig vermieden wird.It is the object of the invention to provide this planographic printing machine to further improve that the stenciling is reduced even further or completely is avoided.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Druckplattenzylinder und die FarbUbertragwalze gleichen Durchmesser aufweisen.This object is achieved according to the invention in that the printing plate cylinder and the ink transfer roller have the same diameter.

Vorteilhaft weisen die Rasterwalze, der Druckplattenzylinder, die Farbübertragwalze und der Gummituchzylinder den gleichen Durchmesser auf.The anilox roller, the printing plate cylinder, the Ink transfer roller and the blanket cylinder have the same diameter.

Bei einer weiteren bevorzugten Ausführungsform der Flachdruckmaschine weisen weiterhin die Walzen des Feuchtwerkes den gleichen Durchmesser auf wie der Druckplattenzylinder und die Farbübertragwalze.In a further preferred embodiment of the planographic printing machine continue to have the rollers of the dampening unit the same diameter as the Printing plate cylinder and the ink transfer roller.

Die Flachdruckmaschine kann auch eine zwischen der Farbübertragwalze und der dem Druckplattenzylinder anliegenden Walze des Feuchtwerks angeordnete Zwischenwalze aufweisen. Vorteilhaft weist auch diese Zwischenwalze den gleichen Durchmesser auf wie der Druckplattenzylinder und die Farbübertragwalze.The planographic printing machine can also have one between the ink transfer roller and the intermediate roller of the dampening unit arranged against the printing plate cylinder exhibit. This intermediate roller also advantageously has the same diameter like the printing plate cylinder and the ink transfer roller.

Durch die Übereinstimmung der Durchmesser der obengenannten Walzen bzw. Zylinder wird eine besonders gUnstige FarbfUhrung erzielt. Das Schablonieren wird weiter reduziert bzw. in vielen Fällen ganz ausgeschaltet.By matching the diameters of the rolls mentioned above or cylinder, a particularly favorable color guide is achieved. The stenciling is further reduced or, in many cases, completely switched off.

Im folgenden wird ein Ausführungsbeispiel der Erfindung anhand der Zeichnung näher erläutert. Die Figur zeigt schematisch einen Schnitt durch eine Flachdruckmaschine.In the following an embodiment of the invention is based on the Drawing explained in more detail. The figure shows schematically a section through a Flat printing machine.

Die Flachdruckmaschine weist ein Farbwerk 13, ein Feuchtwerk 6, einen Druckplattenzylinder 3, einen Gummituchzylinder 11 und einen Gegendruckzylinder 9 auf. Zwischen dem Gummituchzylinder 11 und dem Gegendruckzylinder 9 läuft der Bedruckstoff 10 durch. Das Farbwerk 13 besteht aus einer Rasterwalze 1, der eine Rakel 2 anliegt, und einer Farbübertragwalze 4, die zwischen der Rasterwalze 1 und dem Druckplattenzylinder 3 angeordnet ist.The planographic printing machine has an inking unit 13, a dampening unit 6, a Printing plate cylinder 3, a blanket cylinder 11 and an impression cylinder 9 on. Between the blanket cylinder 11 and the impression cylinder 9 runs Substrate 10 through. The inking unit 13 consists of an anilox roller 1, the one Squeegee 2 is applied, and an ink transfer roller 4, which is between the anilox roller 1 and the printing plate cylinder 3 is arranged.

Die Rasterwalze 1 arbeitet als Tauchwalze und ragt in die Druckfarbenwanne 8 hinein.The anilox roller 1 works as a fountain roller and protrudes into the ink pan 8 in.

Das Feuchtwerk 6 besteht aus den Walzen 5, 14 und 15 und dem Wasserkasten 12. Die Dosierung des Wassers erfolgt über die Einstellung des Anpreßdruckes zwischen den Walzen 14 und 15.The dampening unit 6 consists of the rollers 5, 14 and 15 and the water box 12. The water is dosed by adjusting the contact pressure between the rollers 14 and 15.

Zwischen der Walze 5 des Feuchtwerkes 6 und der Farbübertragwalze 4 ist eine Zwischenwalze 7 angeordnet. Wie die Figur zeigt, weisen alle Walzen bzw. Zylinder gleichen Durchmesser auf.Between the roller 5 of the dampening unit 6 and the ink transfer roller 4 an intermediate roller 7 is arranged. As the figure shows, all rollers or Cylinders have the same diameter.
