Definitions
- the present invention relates to a method for processing at least one gravure printing form consisting of at least one base body and a metallic outer layer carried by it, and a printing form suitable for carrying out this method.
- DE-PS en 27 09 554 and 27 19 275 describes devices for laser processing of gravure cylinders of a conventional type, i.e. That is, gravure cylinders with an outer layer made of electrolytically applied copper. In practice, however, the laser processing of gravure cylinders with an outer copper layer could not prevail.
- the present invention is based on the object of creating a method of the type mentioned at the outset for the laser processing of the metallic outer layer of printing forms which can be successfully used under the conditions prevailing in practice.
- the present invention is based on the finding that the laser processing of gravure printing forms, in particular gravure cylinders, of the conventional type with an outer layer made of copper is associated with difficulties for the following reasons.
- Figures 1-4 show excerpts from variously designed gravure forms.
- the printing form 1 shown only in part in FIG. 1 (in the present case a gravure cylinder as a preferred embodiment) has a base body 2 made of a suitable material, e.g. Steel, aluminum or plastic.
- a metallic intermediate layer 3 is applied to this base body 2 in a known manner, preferably galvanically.
- the intermediate layer 3 consists for example of copper or zinc.
- This intermediate layer 3, which serves to adapt to different cylinder diameters, is also present in the embodiments according to FIGS. 2-4, but is no longer shown in these figures.
- this material has an abrasion and compressive strength that is at least as high as that of copper.
- this material can be machined at least as well as copper and allows the reproducibility of the grid pattern, which is comparable to that of copper.
- a material that has these properties and that also meets the printing requirements is in particular zinc or a zinc alloy.
- these metals and metal alloys must also meet the printing requirements and in particular enable a very high quality of the surface 4a of the outer layer 4. Furthermore, it is important that the ratchet cups 5 can be lifted out in the outer layer 4 by means of laser beams at a very high speed. The latter requirement is particularly important for the processing of gravure cylinders.
- a heat-insulating intermediate layer 6 is arranged below the metallic outer layer 4, which largely prevents the outflow of the heat generated during laser processing from the outer layer 4 into the intermediate layer 3 or the base body 2.
- This heat insulation can be influenced on the one hand by the choice of a material with heat-insulating properties and on the other hand by the thickness of the layer 6.
- Possible materials for this heat-insulating layer 6 are: plastic, ceramic, metals or metal alloys with poorer thermal conductivity than the material from which the outer layer 4 is made. Such metals with poor thermal conductivity are e.g. Titanium, tin, zinc etc.
- other suitable heat insulation materials can of course also be used.
- the outer layer 4 can also be formed from copper.
- the outer layer 4 is designed as a so-called dispersion layer, which consists of a carrier or matrix material 8 and particles 7 embedded therein made of a heat-insulating material.
- These particles 7 can e.g. made of plastic, metal oxides, ceramics, silicon carbide, molybdenum and the like materials.
- the carrier or matrix material 8 can e.g. Zinc, copper or other metallic materials or their alloys are used.
- the incorporation of the particles 7 into the outer layer 4 can have a positive influence on the properties of the outer layer 4 which have a significant influence on laser processing, for example the evaporation energy, the conductivity and the absorption properties of the layer 4.
- the heat flow is not only influenced, as in the embodiment according to FIG. 2, towards the base body 2, but also spatially, i.e. also in the direction of the course of the outer layer 4.
- these particles 8 also significantly reduce the heat outflow in the outer layer, as a result of which, for example, the deformation of extremely thin well walls can be prevented.
- the embedded particles 7 are selected in terms of shape, size and number per unit volume so that the respective printing requirements (e.g. print quality) can be met.
- FIG. 4 Another embodiment is described in FIG. 4.
- a cover layer 9 is applied to the surface 4a of the outer layer 4, which consists of an abrasion and wear-resistant material, e.g. made of chrome or a metal oxide.
- the grid cells 5 are then worked directly through this wear-resistant cover layer 9 into the underlying material of the outer layer 4.
- This embodiment has the advantage that printing form 1 is available for printing directly after laser processing, since chrome layer 9, which is usually only applied after engraving, is already present.
- the material that is used to form the cover layer 9 should form a very stable oxide on its surface, which makes the adhesion of other materials very difficult or even prevents it. This is the case with chrome, for example.
- the metallic outer layer 4 can consist of zinc or its alloys or also other metals and metal alloys including copper. In addition, it is also conceivable to produce the outer layer 4 from a suitable plastic.
- the absorption of the laser beams is increased if the outer layer 4 to be engraved is additionally covered with a black layer.
- This layer can consist of a chemically or electrochemically applied chromium or chromate layer.
- the layer can also be applied by means of a plasma or vacuum coating process and can also be made of other materials, e.g. Paint or plastics.
