Definitions

  • the invention relates to a short inking unit for an offset rotary printing press according to claim 1.
  • Offset short inking units are e.g. B. become known from DE-OS 33 02 872.
  • the invention has for its object to improve the fountain solution in an offset short inking unit.
  • the advantages that can be achieved with the invention are, in particular, that it can be prevented that too much dampening liquid gets into the ink supply of the inking unit and the viscosity of the ink is changed as a result of emulsion formation. It is also easily possible to keep the fountain solution consumption in the inking unit low.
  • a plate cylinder 1 of a printing unit of an offset web-fed rotary printing machine is colored by means of a short inking unit.
  • a dampening unit 2 of known construction dampens an offset printing plate 3.
  • a chamber doctor 4, known per se, is used to supply ink to a screened, hard ink transport cylinder 6 (anilox type).
  • the screened ink transport cylinder 6 is continuously heated to about 40-60 ° in a controlled manner.
  • the offset plate cylinder 1 is brought to a temperature optionally between 20 and 25 ° and kept regulated. Devices for heating or cooling ink and printing unit cylinders have been known for a long time and their description is therefore omitted.
  • an air nozzle row 5 can be arranged parallel to the rasterized ink transport cylinder 6, which blows dried air against the rotating ink transport cylinder 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 cylinder 6 ensure that the excess fountain solution is evaporated on its way to the ink supply, the doctor blade 4 or the ink fountain 9. Blowing the surface of the ink transport cylinder 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 replaced the doctor blade 11 placed on the ink transport cylinder 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 offset printing ink source 4, 9 consists in the special design of the cups 13 and webs 14 of the raster ink transport cylinder 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 or at least less hydrophilic coating e.g. B. nitrided chrome.
