Definitions

  • the invention relates to a short inking unit of a rotary offset printing press according to the preamble of claim 1.
  • Offset short inking units are e.g. B. become known from DE-OS 33 02 872.
  • the heating of the inking unit serves to influence the viscosity of the printing ink used, in the subject of DE-Z to keep the temperature constant in order to keep a constant amount of dampening solution on the printing plate, so less paper dust is built on a rubber blanket.
  • EP 01 77 666 A2 shows a screened roller, the surface of which consists entirely of oleophilic / hydrophilic Fe3O4 material which is permanently oleophilic / permanently hydrophobic.
  • the use of this material lowers the wear resistance of the anilox roller, especially when it comes into contact with a doctor blade.
  • a rastered roller is known, the cells of which are provided with an oleophilic copper layer and whose webs between the cells are made of a wear-resistant material, namely nitrided steel.
  • the invention has for its object to prevent in a short inking unit with a rastered ink transport roller that too much dampening fluid gets into the ink supply of the inking unit.
  • the advantages that can be achieved with the invention are, in particular, that it is prevented that too much dampening fluid in the ink supply of the inking unit changes the viscosity of the ink due to emulsion formation. It is also easily possible to keep the fountain solution consumption in the inking unit low.
  • an air nozzle row 5 can be arranged parallel to the screened ink transport roller 6, which blows dried air against the rotating ink transport roller 6.
  • heat is also given off to the inking rollers 7, 8 and these heat up.
  • the heated inking rollers 7, 8 and especially the heated ink transport roller 6 ensure that the excess dampening water on its way to the printing ink source 4, 9, the doctor blade 4 or the ink fountain 9 is evaporated. Blowing the surface of the ink transport roller 6 with dry air supports the evaporation of the dampening liquid on and in the printing ink on the way back to the printing ink source 4; 9.
  • the doctor blade 4 is through an ink fountain 9 and replaces the doctor blade 11 placed on the ink transport roller 6.
  • An ink fountain roller 12 transports the offset printing ink from the ink fountain 9 onto the surface of the screened ink transport roller 6.
  • Another measure to prevent or reduce the fountain solution transport into the printing ink source 4, 9 consists in the special design of the cups 13 and webs 14 of the rastered ink transport roller 6.
  • the end faces 17 of the webs 14 of the cups 13, over which the doctor blade 11 or the chamber doctor blade 4 slides continuously are chrome-plated, i.e. hydrophilic, and a surface 18 of the cups 13 with an oleophilic one Plating made of nitrided chrome.
