Definitions

  • the invention relates to a method and a device for gravure printing, according to the preamble of claims 1 and 15 an erasable and reusable gravure form, starting from one Gravure blank with a minimum of the maximum to be transferred Basic grid of colors.
  • the type of coloring and the blank coating of the mold surface do not allow pure surface pressure.
  • the whole drawing must be in lines, dots or Raster elements can be resolved. Because of the different depth and size of the individual printing elements, these more or less ink, the As a result, the imprint has different positions at the different parts of the image Color strength.
  • DE 38 37 941 C 2 discloses a method for producing a Intaglio printing form, through which the images take place directly in the printing press can, in addition, the images of the rotogravure form deleted in the printing press and can be prepared for a new illustration. It will too a gravure blank with at least one to be transferred to the maximum Color amount of basic grid produced. Now in the printing press a nozzle of the pixel transfer unit or by image-correlated ironing a quantity of a thermoplastic which is inversely proportional to the image information Substance introduced into the well to increase the volume of the wells reduce. This means that in contrast to the imaging of a gravure blank, the other process applied image material. Can in the press then after the print job the thermoplastic substance by means of a Liquefied heat source and by means of a wiping and / or blowing or Suction device can be removed from the printing form cylinder.
  • the invention is therefore based on the object of a method and to develop a device of the generic type for gravure printing, which improves the positional accuracy of the imaging.
  • Another particular advantage of the method according to the invention and the Device for performing the method is that the Gravure raw mold wear is compensated for because the maximum imaging depth in of the substance on the rotogravure form is significantly less than that original depth of the depressions of the pre-structured raw form. That is because The depth of the depressions due to wear of the webs is smaller, nevertheless maximum imaging depth achievable for a long time.
  • the bars of the raw form as perpendicular to the surface of the gravure form as possible executed in progress.
  • the surface of the gravure form is regenerated again, by cleaning them of paint residues 7, the liquefiable substance is preferred completely detached from the pre-structured depressions 8 and the Wells are filled evenly again.
  • the removal of the liquefied Substance from the pre-structured wells can be created using a heat source and / or blow-out or suction device.
  • the imagewise ablation 3 can be supported in that the filled rotogravure blank 1 is set in rapid rotation such that part of the material to be removed evaporates and a part is thrown off.
  • the gravure blank 1 is not designed as a solid cylinder, but built up in layers to achieve a low heat capacity. So is between the surface layer of a few tenths of a mm thickness, which the Basic grid of the gravure blank 1 carries, and a base cylinder heat insulating layer, e.g. B. provided from glass fiber reinforced carbon.
  • the thermoplastic used for the liquefiable substance can also be a resin, be a synthetic or natural wax.
  • Fig. 4 shows a preferred embodiment of a device for performing of the method according to the invention.
  • FIG. 5 A preferred embodiment of this Device 11 is illustrated in FIG. 5. This includes one to the surface of the Gravure blank 1 open box 11 a with inserted heating cartridges 11 b.
  • the Device 11 is heated and contains the melted thermoplastic 11 c, the can be filled or refilled as granules.
  • the melt 11 c is by gravity and Capillary action promoted to the surface of the gravure blank 1 and penetrates into the Depressions of the basic grid. Gravity can also by Air pressure or hydraulic pressure can be replaced by a pump.
  • By the narrow gap between the gravure blank 1 and the application device 11 acts a capillary and hydrodynamic force that precisely conveys the amount of substance, which is needed to fill up.
  • a constructive variant of this embodiment is that for Device 11 two moldings 11d, 11e (Fig. 5) are provided, one (11e) thereof, viewed in the direction of rotation of the intaglio forme cylinder 10, the another (11d) after the narrow gap between the gravure form 1 and the Application device 11.
  • the molding 11d after the gap is positive through accurate guidance or by supporting jaws against the cylinder 10 in a lot kept a small distance (a few 1/100 mm) and to adjust the viscosity of the filler material can be heated so that the hydrodynamic forces are good are effective and a complete filling of the depressions of the basic grid is guaranteed.
  • the rear edge of this bar 11d is sharp executed to ensure the clean tearing of the filling material from the gap.
  • the front molding 11e is at a greater distance from the cylinder 10 (some 1/100 mm to a few 1/10 mm), so that the thereby increasing Although the gap is filled with material, the hydrodynamic forces are essential look less strong.
  • the actual filling in the area of the molding 11d takes place, in particular by heating and pre-filling the heat-insulated blank printing surface prepared.
  • the liquefiable substance 11 c can also be in excess in the heated state the gravure blank 1 are applied. Then just after cooling the excess portion by means of a doctor blade 12 which can be switched on and off Gravure blank 1 subtracted, that is, doctored and / or polished.
  • the squeegee 12 can change here.
  • the surface of the gravure blank 1 in the filled state repolished to set the roughness of the surface.
  • the Gravure printing form can be colored by means of a coloring system 13. Is preferred a chamber doctor blade is used for this, since it takes up less space on the cylinder circumference needed as a conventional inking system and they while the other Process steps can be easily carried out by the gravure cylinder 10.
  • the application devices 11 are, of course, the Doctor blade 12 and the pixel transfer unit (e.g. the laser 21) and others Equipment from rotogravure cylinder 10 can be switched off before the color and the Protect paint mist.
  • the printing form cylinder does not come with the abrasive medium paper more directly in touch. This allows the use of much softer ones Materials without reducing the service life of the materials.
  • the squeegee, the other wearing part on the printing form cylinder, is due to the webs made of hard material the softer filler material suitable for thermal ablation not either. Through this measure, the service life of an additional Gravure printing plate produced according to the invention significantly improved.
  • the rotogravure plate is printed using a Regeneration device 15, preferably in the form of a Ultrasonic cleaning system, also as an on and off system is similar to a chambered doctor blade, cleaned of paint residues and the liquefiable substance from the depressions of the basic grid of Gravure blank 1 removed so that the cycle (filling 2, imagewise ablation 3, Coloring 4, printing 6, regeneration 7, 8) can begin again.

  • the ultrasonic cleaning system is on at least two different levels operable, a level with low sound energy and / or with a Liquid that only dissolves the color, serves to remove the remaining colors and the other levels with correspondingly higher sound pressures and / or others Cleaning agents for the partial to complete removal of the filling material serve.
  • Another important advantage of the invention is that over the conventional Gravure significantly improved quality, especially text reproduction see. This is achieved in that the write resolution for the imaging well below the distance between two webs, e.g. B. at 500 lines per cm. In order to text can be screened at this high resolution and it is essential to achieve sharper letter edges than in conventional gravure printing. In general, around 400 lines per cm are a good lower limit Text reproduction specified.
  • Conventional gravure mold making has one Resolution of up to 120 lines per cm and must therefore have sharp edges more or less small dots, interrupted by bars, simulate why Gravure printing always has the so-called sawtooth effect.
  • a binary, i.e. H. variable area working imagesetter can write at least 1000 lines per cm.
  • the present invention now prefers, although this binary notation in principle is also suitable to use a mixed form of area-variable and conventional, i.e. H. variable-depth gravure screening, the so-called hybrid screen.
  • This grid is with z. B. 500 lines per cm. However, any point here can be in several depths.
  • the low pressure raw form wear can be compensated for by the fact that the maximum Depth of imaging is significantly less than the depth of the depressions in the pre-structured gravure blank. Now the depth of the wells is through The wear on the webs is less, but the maximum imaging depth is still long reachable. For this purpose, the webs must be closed with walls that are as vertical as possible shape. A narrowing of the depressions due to increasing web thickness can be technically compensated for the exposure by the Volume characteristic is determined from time to time and compensated accordingly.
  • the gravure form can also be regenerated with high pressure water become.
