Definitions
- the invention relates to a thermal method for applying hydrophilic ceramic layers on carrier materials for printing plates. Due to the achievable surface topography, this hydrophilized carrier material is particularly well suited for coating with light-sensitive layers, from which printing plates can be produced, which after exposure and development result in printing forms with a uniform topography, high circulation stability and good dampening solution management.
- the printing plates most frequently used for the offset printing process usually consist of a carrier material onto which a light-sensitive layer is applied in a non-stick manner. This layer is exposed, after which the non-image portion must be removed from the surface without residue. Due to the remaining hydrophobic layer (part of the image), ink can be applied to the product to be printed, but this is only guaranteed if water is present in the area of the non-image areas. For a high quality print image, wettability with water (hydrophilic property) in the area of the non-image areas is of crucial importance. Alumina is known to have such properties.
- DE-AS-13 00 579 has disclosed a method in which a plasma is generated by an electric arc between a heat-resistant electrode and a metallic carrier material in a protective gas jacket, with the aid of which printing plates are roughened with small amounts of waste, and by adding materials the surface can be modified so that it has an improved hydrophilicity.
- this method is difficult to implement in practice, since it is very dependent on the intensities of the transmitted arcs, which are determined by several factors.
- DE-AS-23 48 717 has disclosed a further method for applying layers containing dampening solution to printing plates for the offset printing method.
- Layers of sparingly or insoluble carbonates, silicates or quartz are provided, which are applied to roughened carriers by the plasma spraying process and then ground to produce the appropriate roughness.
- the image portion area is obtained by partially removing the coating.
- this method is very complex.
- the aim of the present invention was to provide a thermal coating process for hydrophilizing surfaces in which not only aluminum supports but also other metals such as steels and other non-ferrous metals and alloys or even plastics can be coated in a controllable and adhesive manner.
- the residues are to be reduced to a minimum and should be created so that recycling is easily possible.
- the aim is achieved according to the invention by a method of the type mentioned at the outset, the characteristic features of which are that, in a first treatment step, a surface roughness R a in the range from 0.3 to 1.5 ⁇ m is produced on the surface of the carrier film by mechanical micro-roughening and that the carrier film is then coated by thermal spraying of powdery oxides and / or oxidic mixtures and compounds with an average grain size in the range from -40 to + 1 ⁇ m with a permanently stable, hydrophilic coating.
- grain size specifications of the type -40 to + 1 ⁇ m mean that there are no particles with a grain size of greater than 40 ⁇ m and no particles with a grain size of less than 1 ⁇ m in the powder with the corresponding grain size specification.
- the hydrophilic layer applied according to the invention fulfills several functions which have a positive effect when coated with photosensitive resins and when used as offset printing plates.
- FIG. 1 schematically shows a process sequence with the enlarged surface states.
- a metal or plastic film 1 as a base support for offset printing plates is continuously unwound from a roll 2 at a constant belt speed, the base support preferably having a thickness in the range from 100 to 500 ⁇ m, particularly preferably from 120 to 350 ⁇ m, and a thickness tolerance of ⁇ 2% with scratch and scar-free surface that is free of coarse organic or mineral residues.
- Aluminum and its alloys of the preferred composition or stainless steels or refined steels can be provided as metallic materials. Other metallic materials that resist corrosion by the dampening solution and that fulfill the mechanical properties can also be used.
- Thermoplastic polyesters can preferably be used as plastics, polyethylene terephthalate-containing homopolymers and copolymers and mixtures thereof with other polyesters or polyamides being particularly suitable.
- the plastics may also contain fillers in an amount of up to 5% by weight, inorganic fillers such as alumina, titanium dioxide and / or aluminum oxide being particularly suitable. There is preferably at least 1.5% by weight of fillers in the plastic.
- the basic carrier 1 is guided over a freely rotating, vertically guided movable roller 3 to accommodate speed compensation and to ensure the largest possible wrap angle for the treatment roller 4 arranged thereafter.
- the form-fitting base body 1 is mechanically roughened according to the invention in a first working step in such a way that a micro-rough surface is produced without damaging the base body by warping.
- Sandblasting processes for rust removal, for removing paint layers or for solidifying surfaces are already known, but it was surprising that thin films can be provided with particularly uniform micro-rough surface topographies with little distortion.
- a 'pressure jet method' is advantageously used, in which the jet pressure is in the range from 0.5 to 2 bar, preferably from 0.6 to 1.5 bar.
- the distance of the nozzle from the base body 1 is in the range from 50 to 150 mm, preferably from 50 to 80 mm.
- Sharp-edged blasting media are particularly suitable as blasting media, in particular mineral blasting media such as Al2O3 or corundum with a grain size in the range from 10 to 100 ⁇ m, preferably from 20 to 50 ⁇ m.
- the amount of abrasive is 500 to 1000 g / irr base carrier, which is dosed consistently.
- the metering is advantageously carried out by rotating mechanical metering devices.
- the blasting device 5 which can optionally also comprise a plurality of nozzles, is moved parallel to the longitudinal axis 6 of the treatment roller 4 at a speed of 1000 to 2000 mm / s. After the blasting process, the surface of the base body is freed of dusts.
- a wear-resistant body with small masses and a flexible rubber pad can be provided as the roller 3.
- the base body belt 1 has a micro-rough surface 7 with a roughness R a of 0.5 to 1.5 ⁇ m, preferably 0.2 to 1.0 ⁇ m, and can be carried out continuously or in increments to the coating station, plasma spraying, be performed.
- the thermal spray process, plasma spraying with a plasma torch 10 in a natural ambient atmosphere with a non-transmitted arc acc. DIN 32530, is known as technology for the application of thick layers.
- Oxide layers, on rotationally symmetrical parts or a surface or partial surface coating with robots by repeated painting, in thicknesses of 50 to 500 ⁇ m are state of the art.
- the base support 1 which can have a width of 500 to 2000 mm, is applied for coating by plasma spraying continuously or cyclically in accordance with the spray jet width, which can be 6 to 12 mm in the zenith, by a driven treatment roller 8 at a speed in the range of 5 to 50 mm / s moved under the hot gas jet of the plasma torch 10.
- the use of several plasma spray guns is particularly advantageous and increases the coating speed many times over, depending on the number of guns.
- an area in the range from 300 to 1000 nr / h can be coated.
- the roller body of the treatment roller 8 which may consist of steel, aluminum or other metal alloys, also has the task of absorbing and dissipating the heat from the thermal process with which the base support for printing plates is inevitably applied. Additional cooling of the roll body with heat-dissipating flow media, avoiding falling below the dew point, results in trouble-free process control.
- Ceramic powder is added by a metering device 12, 13 into the hot gas jet of the plasma torch, which is moved parallel to the longitudinal axis 11 of the treatment roller 8 over the base support 1 at a speed of 1000 to 2000 mm / s in a uniform, undulating or oscillating manner.
- plasma spray layers with a thickness of 5 to 20 ⁇ m and with a layer thickness tolerance of ⁇ 5% can be applied.
- the layers have an adhesion which corresponds to the "film test" as is usual in electroplating. Adhesive strips are pressed onto the coated surface and then jerkily removed again perpendicular to the coating plane. The coating material must not adhere to the adhesive layer. The layers cannot be removed by flaking the base body 1 through an angle of 90 °.
- Argon and nitrogen can be used as the plasma-forming hot gases.
- Gas mixtures such as argon-nitrogen, nitrogen-hydrogen or particularly advantageously argon-hydrogen are advantageously used.
- the electrical power introduced is advantageously 20 to 50 KW, particularly advantageously 25 to 35 KW.
- a very fine powder with an average grain size of ⁇ 20 ⁇ m is used to produce a layer with a roughness R g of 1 to 2 ⁇ m. Powders with an average grain size of 5 to could be particularly advantageous 12 ⁇ m can be used.
- a second powder fraction with a grain size of 20 to 40 ⁇ m, which is expediently added separately, has the effect that, from the basic roughness 14, individual tips 15 that can be controlled in the amount and are distributed statistically uniformly over the surface can be produced.
- the grains can have a different chemical composition, such as round layer AI2O3 - tips AI2O3 + 3%
- aluminum oxides and mixtures or compounds with other oxides can preferably be used which, according to the invention, give a light absorption factor of 50 to 70% on the surface of the layer.
- aluminum alloys such as. B. AlSi, AlMg or Al-Si-Fe and perlet or sintered mixtures with these compositions by oxidation of fine powders, the preferred grain sizes ⁇ 20 microns, oxidic mixtures or compounds with hydrophilic layer properties are generated.
- powdered oxides of the type described as such but optionally also powdered metals which oxidize in the plasma jet, or a combination of these.
- the layer combination of base body and thermally applied hydrophilic ceramic layer has a different hydrophilicity and an increased wear resistance in comparison to the oxide mixtures of metals generated in the plasma gas jet.
- cleaning 16 is expediently carried out by blowing off and sucking off the non-adhering particles. Analogous to the sandblasting process, these can also be returned to the material cycle together with the dusts that are generated in the plasma spraying process.
- the cleaned tapes are then coated at a coating station 17 on the hydrophilized surface 19 with a light-sensitive layer 18. The coated strips are then dried and, if necessary, exposed to tempering processes.
- the printing plates can be cut to their final size from the ribbon material.
- the actual formatting into printing plates takes place in the printing houses, according to known processes.
- a rolled aluminum foil tape WSt. No. 3.0205 with a thickness of 300 ⁇ m and a width of 1600 mm was subjected to a sandblasting process in a first step.
- Two blasting nozzles with a diameter of 8 mm were moved at a distance of 60 mm parallel to the longitudinal axis of the sandblasting roller at a speed of 1.5 mm / s over the film strip.
