Definitions

  • the invention relates to a method for largely preventing the clogging of screened printing plates and a device for carrying out the method according to the preamble of claim 1.
  • the flexographic printing process is characterized by the use of screened rollers, which receive their ink application from a chamber doctor blade, and a plastic printing plate, e.g. B. photopolymer printing plate, colorize (see also DE-OS 33 20 638; DE-OS 31 35 711). The printing surface of the printing plate is rasterized.
  • the invention has for its object to provide a method and a device for performing the method with which it is possible to clog avoid as much as possible screened surfaces of plastic-based printing plates that are colored using water colors.
  • the web-fed rotary printing press in which water-dilutable flexographic printing ink (water-based ink) is used, does not have to be stopped in order to remove the surface d. H. to clean the cells of the screened surface of the pressure plate.
  • a driven anilox roller is mounted in side frames.
  • One or more ink application bars are arranged on and off the anilox roller.
  • An upper doctor blade and a lower doctor blade are attached to the ink application bars.
  • the paint application bar is with one opposite the outer surface, over the entire length of the paint application bar extending recess provided. This recess is connected to a paint feed device via a through hole.
  • the anilox roller colors the printing plates on a plastic basis, e.g. B. photopolymers.
  • water is continuously supplied to the chamber of the flushing inking unit via the through-hole, which is optionally kept at a temperature between 9 and 14 degrees Celsius.
  • This water color is continuously fed to the flushing inking unit and the excess water color is continuously removed from the inking unit and returned to the ink supply and temperature control device.
  • the ink supply and tempering device keeps the temperature of the water color constant at an optionally set temperature between 9 and 14 degrees Celsius.
  • the anilox roller is hollow and is connected via known rotor connections via feed and return lines to a device for supplying and tempering water color of a preselectable temperature.
  • the water circulation is adjusted so that the surface temperature of the anilox roller is kept constant at a temperature that can be preselected between 18 and 22 degrees Celsius.

Claims (2)

  1. Procédé permettant pratiquement d'empêcher tout bouchage de surfaces tramées d'un cliché encré avec des aquateintes, d'une machine à imprimer à rotation à rouleaux, destinée à imprimer un support d'impression, de préférence en papier, caractérisé en ce que de l'aquateinte est amenée en continu à un groupe d'impression, à une température pouvant être présélectionnée, située entre 9 et 14°C, en ce que l'aquateinte non consommée est enlevée en continu du mécanisme d'impression, et en ce que la température des surfaces du rouleau tramé du groupe d'impression est maintenue constante, à une température pouvant être présélectionnée entre 18 et 22°C.
  2. Dispositif pour mettre en oeuvre le procédé selon la revendication 1, caractérisé en ce que le groupe d'impression travaillant à l'aquateinte est relié à une machine à imprimer rotative à rouleaux, travaillant selon le procédé d'impression flexographique, pour imprimer un support d'impression, de préférence en papier, avec un dispositif maintenant l'aquateinte à une température pouvant être sélectionnée entre 9 et 14° C, en vue de maintenir constante sa température de surface, d'une façon pouvant être sélectionnée, entre 18 et 22° C.
