Definitions

  • the invention relates to a method and an apparatus for Generate an embossed print on a substrate according to the Features of the preamble of the independent claims.
  • Printed matter such as Stationery is often added embossed for printing. Next Such an embossed print offers aesthetic aspects Guarantee function. Based on the embossing, it can be determined whether the stationery is an original or one Copy acts.
  • DE 44 353 06 describes a device for punching, perforating or the like in a sheet offset machine.
  • a tool carrier shaft runs parallel to the impression cylinder arranged, which carries tool carrier rings and rotates in the machine cycle.
  • From DE 44 353 07 is also a method and Device for perforating, punching, embossing or the like known in a sheet offset machine. In addition to printing further operations carried out in one sheet pass become. According to this document, the substrate is in one Processing plant processed and subsequently printed.
  • DD 231 760 describes a device for embossing on rotary machines known, the offset printing machines Rubber blanket as a matrix and the bimetal embossing plate as a male are arranged on the printing cylinder.
  • DE 27 36 213 describes a method for printing and Embossing thin foils known. Subsequent to one to six printing units of a printing press is an embossing cylinder provided that operated synchronously with the printing press becomes.
  • the procedure is supposed to also on a conventional offset press without big additional effort to be carried out.
  • the device by converting from a conventional Offset printing machine can be manufactured.
  • the offset rotary printing press has at least one offset printing unit on.
  • the offset printing unit is with a plate cylinder with an offset plate, a rubber cylinder with a rubber blanket and a pressure cylinder.
  • the offset printing unit (in the case of a single printing unit) or an offset printing unit (in the case of several printing units) is designed according to the features of the invention as an embossing unit.
  • the substrate between the offset plate is used for embossing and the rubber blanket passed through it Depressions or protrusions deformed on the offset plate, i.e. embossed.
  • the offset plate is preferably with a Provide engraving into which the printing material can be pressed is. On the rubber blanket, a Survey. The elevation presses the substrate in the engraving of the offset plate.
  • the device according to the invention or the device according to the invention Processes make it easy to convert from conventional ones Printing units. Instead of a conventional offset plate, in one of the printing units, preferably in the last printing unit, one Offset plate used with a recess or elevation become. On the rubber blanket are also on appropriate Provide surveys. Otherwise there are no modifications compared to a conventional printing unit.
  • the Printing material in the embossing unit between the offset plate and the Rubber blanket passed through.
  • the embossing in last offset printing unit mounted in a printing press In ink can be applied to previous printing units.
  • the engraving on the offset plate of the last printing unit is advantageously arranged so that the preceding printed areas.
  • the offset plate typically has a thickness of 0.3 mm on (conventional offset plate).
  • the depth of the engraving is about 0.1 to 0.2 mm.
  • the patrix is advantageously worn on the rubber blanket Surveys formed, for example by glued Blotting paper.
  • inventive Method and the device according to the invention only for Use embossing, i.e. no previous printing.
  • the direction in which the substrate is passed through the printing unit is of secondary importance Importance.
  • the substrate it is also conceivable for the substrate to pass directly between the rubber blanket and the offset plate. In this case, however, it is necessary to use the embossing mill compared to a conventional printing unit modify, especially to change the direction of movement.
  • Figure 1 shows an offset rotary printing press 1.
  • the offset rotary printing press 1 consists of four in succession switched offset printing units 2, 2 '. Of course more than four printing units are also conceivable.
  • a printing substrate 10 is guided in a conventional manner through the first three offset printing units 2 '.
  • Various color prints are applied.
  • the representation of the offset printing units 2 ' is schematic.
  • the components required for an offset printing process such as inking cylinders, dampening cylinders etc., are also available.
  • conventional white 80 g / m 2 paper is used as printing material.
  • the fourth and last printing unit is designed as embossing unit 2.
  • the printing material 10 becomes the last of the three offset printing units 2 'guided over a turning bar 11, vice versa and finally headed to embossing 2.
  • the embossing unit 2 is like a conventional offset printing unit educated.
  • the embossing unit 2 has a pressure cylinder 7, a rubber cylinder 5 with a rubber blanket 6 and a plate cylinder 3 with an offset plate 4.
  • the printing material 10, which is reversed by means of the turning bar 11 was between the printing cylinder 7 and the rubber blanket 6 initiated in the stamping mill 2. Then the Printing material 10 around the blanket cylinder 5 and between the Rubber blanket 6 and the offset plate 4 passed through.
  • a device 12 for beating the Printing material 10 provided with UV radiation is also a device 12 for beating the Printing material 10 provided with UV radiation.
  • Figure 2 shows an enlarged view of the as embossing 2 trained last offset printing unit.
  • the embossing unit 2 is similar to a conventional offset printing unit educated. Ink and moisture application cylinders are schematic 13 shown, which, however, in the embossing mill 2 do no task.
  • the Offset plate 4 which is attached to the plate cylinder 3 is provided with an engraving 8.
  • An embossing is created in this way.
  • the embossing mill 2 runs synchronously with the upstream offset printing units 2 '. Instead of that in embossing 2 like conventional offset presses Another color is printed on the same Make an embossing. The previous ones Printing applied to offset printing units minted afterwards.
  • FIG. 3 shows an enlarged illustration of the routing of the printing substrate 10 between the impression cylinder 7, the rubber cylinder 5 and the plate cylinder 3.
  • Elevations 9 are provided on the surface of the rubber blanket 6. A patrix is thus formed on the rubber blanket 6.
  • the elevations 9 are formed, for example, by blotting paper with a thickness of 0.2 mm. Typically, blotting paper 100 gm 2 can be used.
  • the paper for forming the elevations is typically stuck on, for example with self-adhesive film.
  • Figure 4 is the interaction between the female and male shown in detail.
  • the patrix is covered by the rubber blanket 6 formed, which is provided with elevations 9.
  • the die is formed by the offset plate 4, which has an engraving 8 having.
  • the offset plate 4 is a conventional offset plate, for example made of aluminum.
  • the thickness d is 0.3 mm.
  • the depth t of the engraving is 0.2 mm.
  • the offset plate 4 is like in conventional offset printing units easily exchangeable held on the plate cylinder 3. To the Creating a certain embossing is an offset plate, which has a corresponding engraving on the plate cylinder 3 put on.
  • the blotting paper comes with a double-sided self-adhesive film based.
  • the applicable thickness depends on the formative printing material 10.
  • the blotting paper is moistened and a print run with the Matrix 8 made.
  • the non-formative parts are with a Knife removed.
