Description

Die Erfindung betrifft ein Druckklischee für Tampon­ druckmaschinen und ein Verfahren zu seiner Herstellung.The invention relates to a printing block for tampons printing machines and a process for its manufacture.

Derartige Druckklischees oder Druckplatten wurden bisher aus Stahl oder dergleichen Material hergestellt. Abge­ sehen von dem hohen Gewicht ist die Oberflächenbehandlung des Stahls wesentlich aufwendiger.Such printing blocks or printing plates have so far been used made of steel or the like material. Abge The high weight is the surface treatment of the steel much more complex.

Durch die DE-OS 28 11 396 ist auch schon ein Druckklischee für den Offsetdruck bekannt geworden, das aus einem Alu­ miniumschichtträger besteht, auf dem eine Oxydschicht und darüber eine lichtempfindliche Schicht vorgesehen ist. Mittels der lichtempfindlichen Schicht wird das Druckbild in bekannter fototechnischer Weise erzeugt. Ein derartiges Druckklischee oder Druckfolie ist jedoch für den Tampon­ druck wenig bis gar nicht geeignet, einmal weil die Druck­ folie nicht eingespannt werden kann und zum anderen weil die oberste Schicht mit dem Druckbild nicht genügend Druck­ farbe aufnehmen kann, um einen Tampondruck durchzuführen.DE-OS 28 11 396 is also a printing cliché known for offset printing, which is made of an aluminum minium layer carrier exists on which an oxide layer and a photosensitive layer is provided above it. The printed image is made by means of the light-sensitive layer generated in a known photo-technical manner. Such a thing Printing cliché or printing film is, however, for the tampon print little or not suitable at all, partly because of the pressure film can not be clamped and secondly because the top layer with the printed image does not have enough print ink can take up to pad printing.

Die DE-PS 5 44 156 befaßt sich mit einem Verfahren zur photo­ mechanischen Herstellung von Aluminium-Druckformen, und zwar insbesondere damit die gehärtete Kolloidschicht nach der Belichtung zu entfernen. Dabei ist auch erwähnt, daß die Druck­ platte nach der Belichtung gegebenenfalls geätzt werden kann. An eine Vertiefung der freigelegten Aluminiumflächen durch Ätzen ist hierbei nicht gedacht.DE-PS 5 44 156 deals with a method for photo mechanical production of aluminum printing forms, namely especially so that the hardened colloid layer after the  To remove exposure. It is also mentioned that the pressure plate can be etched after exposure if necessary. A deepening of the exposed aluminum surfaces Etching is not intended here.

Aufgabe der Erfindung ist es, ein Verfahren zur Herstellung einer Tampondruckform zu schaffen.The object of the invention is a method for the production to create a pad printing form.

Die Erfindung ergibt sich aus dem Patentanspruch.The invention results from the patent claim.

Die Erfindung zeichnet sich durch einfache Herstellung sowie niedrige Material- und Herstellungskosten aus. Außerdem läßt sich die neue Druckplatte sehr einfach und vorteilhaft in Tampondruckmaschinen einsetzen, insbesondere deshalb, weil die Ätzung der obersten Schicht die Aufnahme von sehr viel Farbstoff gewährleistet.The invention is characterized by simple manufacture as well low material and manufacturing costs. Also lets the new printing plate is very simple and advantageous Use pad printing machines, especially because the etching of the top layer absorbing a great deal Dye guaranteed.

Die Erfindung wird anhand der Fig. 1 und 2 näher er­ läutert, wobei:The invention is explained in more detail with reference to FIGS. 1 and 2, wherein:

Fig. 1 die Druckplatte und Fig. 1 the pressure plate and

Fig. 2 den Schnitt A-A der Fig. 1 zeigt. Fig. 2 shows the section AA of Fig. 1.
