Definitions

  • the invention relates to an inking unit and optionally a dampening unit of a printing unit of a processing machine according to the preamble of claim 1.
  • the printing unit is particularly suitable for offset printing.
  • DE 40 13 463 C2 shows a printing unit of a rotary printing press with a form and a transfer cylinder, wherein an inking unit and a dampening unit are arranged on the forme cylinder.
  • the inking unit supplies ink to the printing areas of a printing plate arranged on the forme cylinder, while the dampening unit moistens the non-printing areas of the printing plate.
  • a disadvantage of this device is that the ink accumulating on the application roller of the dampening unit can be guided into the dampening unit and that the dampening agent accumulating on the application rollers of the inking unit can be guided into the inking unit and thus the colorant / dampening solution balance in the printing unit is impaired ,
  • These fluctuations can be manifested on the substrate in the form of visible disturbances, for example stenciling phenomena, roller strips or cord strips (streaks).
  • a printing unit roller adapted to the subject in terms of its hydrophilic and / or oleophilic properties can be used in a simple manner. It is thus a good homogenization of the color ⁇ / Vasseremulsion preferably achievable on wet and inking rollers. Disturbances so far from the plate cylinder channel, roller strips and subject are noticeably reduced, so that the print quality can be improved.
  • Fig. 1 a dyeing and dampening unit, partially shown
  • Fig. 2 a dampening unit.
  • FIG 1 a form cylinder 1 and an inking unit 2 and a dampening unit 3 of a printing unit are partially shown.
  • the inking unit 2 only two inking rollers 4, 5 are shown, wherein on the former a rider roll 6 is arranged, which has a lateral surface with hydrophilic and oleophilic surface portions.
  • the rider roll 6 is mounted together with two other rider rolls 7, 8 in a magazine 9, wherein the other rider rolls 7, 8 each have to the rider roll 6 other hydrophilic and oleophilic properties.
  • the magazine is designed similar to a turret.
  • a bridge roller 11 is further shown, which is in communication with the inking roller 5 and with a dampening roller 12 of the dampening unit 3.
  • the bridge roller 15 has a lateral surface with hydrophilic and oleophilic surface portions.
  • the bridge roller 11 is held with two other bridge rollers 13 and 14 in a magazine 15, wherein the other bridge rollers 13, 14 to the bridge roller 11 each have other hydrophilic and oleophilic properties.
  • the bridge roller 11 is movable out of its shown insertion position and, depending on the direction of rotation, the bridge roller 13 or 14 in the insertion position into movable.
  • a dampening unit 18 is arranged on a partially illustrated forme cylinder 17.
  • the latter includes a dampening roller 19, which is supported in a magazine 22 together with two other dampening rollers 20 and 21.
  • the dampening roller 19 is out of its shown insertion position and depending on the direction of rotation one of the two
  • Dampening rollers 20 or 21 movable into the insertion position.
  • the magazine 22 Before execution of the rotation 23, the magazine 22 performs a pivoting 24, in which the dampening form roller 19 is moved away from its adjacent roller of the dampening unit 18. Instead of the pivoting 24, a shift could also take place.
  • the dampening application roller 20 or 21 After the dampening application roller 20 or 21 has assumed the position of the dampening application roller 19, the magazine 22 is again moved towards the dampening unit 18.
  • the dampening roller 19 has a lateral surface with hydrophilic and oleophilic surface portions.
  • the dampening rollers 20 and 21 have opposite the dampening roller 19 each have other hydrophilic and oleophilic properties.
  • the hydrophilic and / or oleophilic surfaces of the printing unit rollers located in the magazines 9, 15, 22 could also have different surface energies.
  • Materials having hydrophilic or oleophilic properties for the surfaces of the printing-unit rollers are familiar to the person skilled in the art and are mentioned, for example, in DE 102008007679.1.

Abstract

L’invention concerne un dispositif encreur (2) et le cas échéant un dispositif de mouillage (3) pour un dispositif d’impression d’une machine de traitement comprenant au moins un cylindre d’impression avec une surface ayant des parties de surface hydrophiles et oléophiles. Afin d’obtenir un bon équilibre entre agent colorant et mouillant, le cylindre d’impression peut être remplacé par au moins un autre cylindre d’impression avec d’autres propriétés hydrophiles et oléophiles.
