  • dampening inking unit A disadvantage of this dampening inking unit is that the dampened printing form, especially when Printing fuzzy substrates, washed relatively often must, because of a lack of rolling slip between the Dampening roller and the printing form so-called slugs in the print image Place the free paper fibers causing them on the printing form.

  • dampening systems have to meet the highest requirements. By a can only roll on the dampening roller these requirements when designing dampening systems correspond.

  • Unfavorable on this dampening system is that a dampening system for indirect dampening a Plate cylinder is not provided.
  • the employment of the dampening roller to the closest inking unit roller either serves to use the Damp applicator roller as the only printing ink on the plate cylinder applying application roller or as a washing circuit.
  • the dampening roller is switched off from the dampening roller mounted in a side frame connected so that a stencil-free indirect dampening with this Dampening is also not possible for this reason.

Only from the The dampening roller runs on ink supply of separate pure direct dampening at a peripheral speed which is about 10% above or below the Circumferential speed of the plate cylinder is. Very disadvantageous about this Dampening is that this does not have the dampening film on the Moist application roller smoothing and only on this Dampening roller is provided adjacent dampening roller.

It has been shown that when using the inking unit to which the inking roller belongs, as a so-called short inking unit, increased requirements for incorporation the dampening solution into the ink on the dampening roller consist. In the so-called short inking unit operation, the Planographic printing form not all of the inking rollers of the total Inking unit used.
