Definitions

  • the invention relates to a method and a rotary printing press for indirect gravure printing.
  • the traditional gravure printing unit includes an intaglio cylinder, an intermediate roller and an impression roller, as shown in FIG. 1.
  • the web is printed on one side as it passes between the gravure form cylinder and the intermediate roller.
  • the web must have a high smoothness due to the contact with the hard printing form.
  • Another disadvantage is that low-viscosity, solvent-containing printing inks are used so that the cells of the printing form can be reliably filled and emptied during printing. The solvent vapors pollute the environment.
  • the low viscosity solvent-based ink also requires intermediate drying between the printing inks in multi-color printing, since otherwise the color dots would run together on the printing substrate.
  • the older application P 43 28 027 shows a printing unit for newspaper printing in indirect gravure, in which the intaglio printing cylinder, transfer cylinder and impression cylinder have the same diameter and the printing form is inked with a water-soluble ink by means of a chamber doctor blade.
  • a rotary printing press must be created to carry out the method.
  • this object is achieved by a method having the features of patent claim 1 and by a device having the features of patent claim 5.
  • the invention avoids stickiness, the so-called tak, as a result of which the wells of the gravure printing plate can be filled reliably.
  • the cover of the transfer cylinder with its smooth surface can print the ink well from the cells of the printing form suck and empty them to a large extent.
  • the closed surface of the cover also prevents penetration and thus shearing off of thinners of the paint and thus swelling of the surface.
  • the rubber blankets or elastomeric covers known from offset generally have an amorphous structure, which in conjunction with pasty, oily printing inks leads to greater adhesion of the ink film than on the printing form with subsequent ink film splitting when transitioning to the printing material.
  • the film splitting largely takes the place of the transfer of ink from the transfer medium to the printing material. The complete detachment of the image on the transfer medium as a color film is a function of the wettability, surface roughness and layer crosslinking of the outer cover in relation to the surface tension of the printing ink.
  • the cover of the transfer cylinder also fulfills considerable mechanical requirements.
  • the elastic, radially compressible cover has no resistance on the cells, in contrast to the cylinder surface, which leads to considerable transverse expansion in the pressure line.
  • the 1: 1 unwinding ratio means that the compressed pressure line is permanently shifted in the rotation without any relaxation, in contrast to the offset.
  • the extremely radially compressible cover with very high restoring forces (rebound - elasticity) does justice to this situation.
  • the slightest damping (displacement) would lead to considerable tangential forces that could not be absorbed by the connection joint of the cover to the body of the transfer cylinder.
  • all customary color systems such as water-soluble, radiation-curable and offset inks, are also included environmentally friendly colors, processable. Thanks to the higher viscosity of the inks compared to conventional solvent printing inks, disadvantageous intermediate drying in multi-color printing between the individual printing units is not necessary.
  • the drive connection of the forme, transfer and impression cylinder is a prerequisite for a slip-free rolling of these cylinders and thus a clean, smear-free print.
  • the indirect printing in conjunction with the eccentric print shutdown allows simple, compact machine configurations analogous to offset printing, such as I-printing units, H-printing units, U-printing units, etc., allowing the web to be printed on both sides. Thanks to the elastic cover, it is also possible to print on substrates with a rough surface, e.g. for newspapers and packaging.
  • the traditional gravure printing unit shown in FIG. 1 contains an intaglio forme cylinder 1, which is immersed in the printing ink of an ink trough 2, as well as an intermediate roller 3 and an impression roller 4. During the passage between the intaglio printing forme cylinder 1 and the intermediate roller 3, the web 5 is printed on one side.
  • the intaglio printing unit shown in FIG. 2 has two printing units 6, 7, each with an intaglio printing cylinder 8, 9 and a transfer cylinder 10, 11. All cylinders 8 to 11 are mounted in the side walls 12, 13 of the printing unit, the transfer cylinders 10, 11 being received in eccentric bushes 14 to 17 (FIG. 3).
  • the transfer cylinders 10, 11 can be adjusted both against the gravure forme cylinders 8, 9 of the respective printing unit 6, 7 and against one another.
  • the pins 18 to 21 of the cylinders 8 to 11 each have a spur gear 22 to 25 and are thus in drive connection with their respectively adjacent cylinder.
  • a chambered doctor blade 26, 27 is placed on each gravure forme cylinder 8, 9 and is supplied with ink by means of a pump 28, 29 via a feed line 30, 31. Return lines 32, 33 lead from the chamber doctor blades 26, 27 to ink containers.
  • the intaglio printing forms located on the intaglio cylinders 8, 9 are inked by the chamber doctor blades 26, 27.
  • a water color with a viscosity of approx. 80 to 120 mPa s is used.
  • other colors for example radiation-curable or offset inks with a viscosity of at least 80 to a maximum of 1000 mPas, can also be printed.
  • the chambered doctor blades are advantageously operated with ink circulation, ie the pumps 28, 29 convey more ink than is required for printing. The excess paint is fed back via the return lines 32, 33 to the paint containers 34, 35.
  • the intaglio printing cylinder 8, 9 is rolled off with the respective transfer cylinder 10, 11, the colored cells give off the printing ink to the latter. These in turn transmit the printed image to the web 36 passed between them in mutual rolling contact.
  • the transfer cylinders 10, 11 each have a cover made of a fully crosslinked aliphatic polyurethane. Silicone could also be used.
  • the cover 37 is advantageously applied to a metallic carrier sleeve 38. This reference sleeve 39 is shown in FIG. 4.
  • the cover 37 has a roughness depth R z ⁇ 6 microns.
  • the radial rebound elasticity of the cover is greater than 95%, its compression set less than 5%, preferably less than 2%, its hardness 70 to 80 Shore A. Its density is 0.30 to 0.65 g / cm3.
  • Such transfer cylinder sleeves are described in DE 39 08 999 C2.
  • the change of the reference sleeve 39 is shown for the transfer cylinder 10 in FIG. 5.
  • the wall piece 40 is removed from the side wall 13.
  • the opening 41 thus created the diameter of which is larger than the outer diameter of the reference sleeve 39, the latter is now pushed axially by the cylindrical body 42 of the transfer cylinder out of the printing unit.
  • the intaglio printing forms of the intaglio printing cylinders 8, 9 are also advantageously sleeve-shaped, which can also be changed using the principle shown in FIG. 5.
  • the reference sleeves or shaped sleeves can also be changed after the corresponding cylinders have been removed from the printing unit, for which purpose slots in the side walls are created by removing filler pieces.
  • the gravure form cylinder can also, for example, with individual printing forms placed with a butt, e.g. B. magnetically adhesive.
  • the intaglio printing plate can also be firmly attached to the cylindrical body of the intaglio printing cylinder.
  • the cylinder can be imaged and deleted in the printing press.
