- the invention relates to a method and an apparatus for producing a Printing form according to claims 1 and 21.
- the printing form it can z. B. act as a flexible or flexographic printing plate, the high pressure or Gravure form can work.
- a printing plate which can be a polymer plate, for example, in order to produce a relief in the printing plate in this way in order to produce a flexographic printing plate with the aid of a conventional CO 2 laser.
- the CO 2 laser is permanently power-modulated in order to obtain recesses in the surface of the printing plate that limit the relief.
- the prior art also includes methods for inserting small halftone dots to lower a relief. This happens because of focused rays striking each other in corresponding areas and that Remove material in accordance with the focused course of the rays. This results in a kind of cone, the cone tip of which is more or less is deep in relief. Will be below the printing form during later printing an offer arranged, so a kind of pad, so through this pad the tip of the cone is raised again in the area of the pressure surface. Printing material adheres poorly to this cone tip, so that an unclean print image results. Cone tips representing halftone dots of this type, e.g. B. provided in the area of solid areas to the To be able to better emphasize solid areas in later printing.
- US-A-5,427,026 already discloses a method for producing a Printing form in which a relief is created in the surface of a printing form blank is introduced that material of the printing form blank along Traces are removed in areas by radiation. There will be recesses formed between which plateaus come to rest. These recesses can then be lowered completely or in some areas. This creates deeper plateaus.
- the last-mentioned document also discloses a device for manufacturing a printing form.

Beyond that created a corresponding device for producing such printing forms become.
- One method of making a printing form is in the original surface of a printing form blank a relief is introduced in that material of Printing form blanks removed along areas by traces by radiation to thereby form recesses between which plateaus come to rest.
- a plateau lying in the original surface of the printing form blank between successive recesses by means of one in the longitudinal direction of the track moved moving beam evenly, so that the obtained lower lying plateau with its surface parallel to the original Surface of the printing form blank is.
- the depth of the lower lying plateaus the surface lying between the recesses of the printing form blank in accordance with its intensity or performance adapted radiation are removed. So should those between the Recesses lying plateaus are burned away over a greater depth, the intensity or power of the beam must be increased, and vice versa.
- the Depth of the lower plateaus is the one between the recesses Surface of the printing form blank also removed by repeated irradiation become.
- This repeated irradiation of the printing form blank in the area the plateaus for generating the lower-lying plateaus thus take place staggered in time or one after the other, so that a lower lying plateau virtually is obtained by repeatedly peeling off the printing plate material.
- the beam power be relatively small, which means that even very fast modulators can be used to switch the beam power on and off, when using the beam power must be limited, to prevent the modulators from being destroyed, such as acousto-optic modulators.
- the printing plate material after each removal process cools down again before it is removed again, which leads to that the printing form material does not heat up so much in the plateau region and thus the relief is extremely precise or true to form can be.
- the material removal can occur between the individual burning processes also be dissipated, e.g. B. be sucked off, which is a more accurate Working at the next removal process enables and qualitatively better Structures leads.
- Irradiation of the plateaus along a respective track can also occur and the same beam that is repeatedly guided along a track becomes. But it is also possible that the irradiation along a track with several Beams are carried out, which are guided in succession along the same track.

- Carriage 23 is fixed, is therefore no longer in the longitudinal direction of the cylinder trained printing form blank slidably. Rather is now the printing form blank 1 is mounted displaceably in its cylinder longitudinal direction, to which he is now arranged on the guides 24 and z. B. with Help of the screw 25 is driven, which in turn from the rotary drive 26 is rotated in one direction or the other.
- This is an advantage Arrangement if very many lasers for simultaneous processing of the Printing form blanks 1 are used because this variety of Lasers are then no longer stable and low in vibration on a movable one Carriage can be transported.
- FIG 10 A fourth exemplary embodiment of the system according to the invention is shown in FIG 10 shown.
- three focused laser beams 28a, 28b, 28c arrive at the same time to a circumferential direction of the cylindrical printing blank 1 running track.
- the focused laser beams 28a to 28c are in offset in this circumferential direction. They are created with the help three lasers 27a, 27b and 27c, which are arranged on the carriage 23, for example one above the other are arranged horizontally and by three acousto-optical modulators 30a to 30c are switchable or modulatable.
- the focus is with Using three lenses 32a to 32c, with the top and bottom Beam deflecting mirrors 31a and 31c are provided.
- FIG. 11 shows a cross section through a flexographic printing forme, which is a larger one Has full surface U, which is surrounded by a grid of points, the through several small mountain-like structures with plateaus P2a, P2b, P2c and P2d is formed, which are separated from one another by recesses V.
- the full surface U lies in the surface 2 of the printing form blank 1, while plateaus P2a, P2b, P2c and P2c lie below surface 2, and the deeper, the closer they are to the full surface U.
- the printing form shown in Figure 11 for the purpose of printing on the Surface of a roller 53 is placed, and is between the full surface U and the Roller 53 a pad 54 (addition) arranged, the printing form in Area of the full surface U is relatively strongly compressed when this against a Printing surface 55 is pressed.
- the pad 54 is limited to the area of the full surface U, the pressing force against the pressure surface 55 being so is chosen that the surface 2 lying outside the full surface U of the Printing form just comes into contact with printing surface 55 and is practical is not or only slightly pressed. Due to the existence of the document 54 of course, the lower lying plateaus during the pressing process P2a, P2b, P2c and P2d increased, the latter more than the former.
