Definitions

  • the invention relates to a short inking unit of a rotary printing press according to the Preamble of claim 1.
  • WO 91/13 761 A1 describes a short inking unit of a rotary printing press, wherein The forme cylinder and inking roller have the same diameter.
  • the An oscillating smoothing roller is assigned to the inking roller.
  • US 43 32 195 A discloses an inking unit with an anilox roller, one axially movable smoothing cylinder is arranged.
  • the smoothing cylinder and the inking rollers have different diameters.
  • EP 04 18 778 A2 shows an inking unit with axially movable inking rollers. about the ratio of the diameter of inking rollers and forme cylinders is nothing known.
  • the invention has for its object a short inking unit To create rotary printing press.
  • This short inking unit without zone screws is preferably used in offset printing machines for Quality job printing arranged.
  • Such inking units are known. They are two rollers with anilox and applicator roller educated. They are enough for good newspaper quality. With commercial quality on coated Papers with z. B. 70 iger image grid you need anilox rollers with correspondingly finer Engraving than in newspaper printing to avoid moiree appearances. such However, anilox rollers are sensitive to mechanical damage.
  • a coarser, i.e. H. mechanically more stable structure of the anilox roller can also be used for fine screens if the color film with coarse screen on the Application roller is smoothed before the plate is touched.
  • the smoothing cylinder is only reciprocated once in two revolutions. In the first turn, it makes a one-way walk of approximately 15 over the entire printing process up to 20 mm. The movement is reversed in the cylinder channel of the applicator roller. In the second turn the smoothing cylinder runs back - again over the entire Print run length without reversal of motion. The reverse takes place in the Cylinder gap. This ensures that there are no color differences due to standstill or Reversal of movement of the smoothing cylinder on the applicator roller, the plate and thus in Print image on paper become visible.
  • the axial stroke of the smoothing cylinder must be so large that in Contact strips between the smoothing cylinder and inking roller more than a well or a hashing distance is rubbed laterally on the anilox roller.
  • the smoothing cylinder must be the minor one Change the position of the applicator roller, d. H. the bearer ring contact remains receive appropriate measures.
  • An inking unit of a rotary printing press preferably one Offset rotary printing machine, essentially has an anilox roller 04 (anilox roller), a first ink roller 04, e.g. B. an inking roller 04, and another inking roller 05, e.g. B. a smoothing cylinder 05 on.
  • the anilox roller 03 is one for ink supply Doctor device 02, z. B. assigned a doctor blade 02.
  • the ink is preferably pasty and has a viscosity greater than 9000 Pa ⁇ s.
  • the inking roller 04 colors a printing form, for. B. a printing plate of a forme cylinder 06, e.g. B. a plate cylinder 06 a.
  • This forme cylinder 06 acts with a transfer cylinder 07, e.g. B. rubber cylinder 07, together.
  • This transfer cylinder 07 forms a counter pressure cylinder 08 Print location.
  • the impression cylinder 08 can also be used as a "hard" impression cylinder 08 for example, holding elements or a second transfer cylinder.
  • An inking unit can be assigned to the forme cylinder 06, with the radius r04 then Ink roller 04 with the radius r06 of the forme cylinder 06 are the same.
  • the inking roller 04 preferably contacts both the forme cylinder 06 and the die cylinder Anilox roller 03. There are also several equal-sized ink rollers between Anilox roller 03 and forme cylinder 06 possible.
  • This inking roller 04 is another inking roller 05, e.g. B. a smoothing cylinder 05 assigned.
  • the inking roller 04 and / or the smoothing cylinder 05 perform an axial stroke Direction out.
  • a ratio of the circumferential length per angular unit of the changing ink roller 04; 05 based on the stroke per angular unit of the inking rollers 04; 05 is 2.5 to 5.
  • the smoothing cylinder 05 preferably oscillates and the inking roller 04 is axial Direction fixed.
  • a ratio of a grid of the anilox roller 03 to a ratio of a grid of Printing form of the forme cylinder 06 greater than 0.5, in particular greater than 0.8.
