Definitions

  • the invention relates to a roller, preferably for a dampening unit of a printing press, which can be used universally. It can be used, for example, as a dampening roller, metering roller or dampening roller.
  • Dampening units essentially have rollers made of steel, rubber or textile covers. In some cases, the wettability of the roll surface is only possible with the aid of hydrophilizing agents.
  • a dampening roller is known from EP 0 400 621 A2, the base body of which is coated with ceramic / metal carbides. Using special processes (laser / radioactive radiation), indentations are made in the coating to increase the dampening solution flow.
  • a disadvantage of this type of roller is that the wettability of the rollers (dampening solution guidance) decreases when alcohol is added or no dampening solution is added. Since stable dampening solution guidance is no longer guaranteed, color fluctuations occur (the ink / water balance is disturbed) and registration difficulties.
  • DE 4 229 700 A1 discloses a further dampening roller which is said to have good hydrophilic properties.
  • the disadvantage here is that the silicon-metal surface has pores and must be sealed in order to avoid printing disadvantages, which is a complex process.
  • the object of the invention is to develop a roller for a dampening unit, the surface of which has a high wettability with water or dampening solution. This object is achieved according to the characterizing part of the main claim. Further training results from the subclaims.
  • a dampening roller of this type has a coating which consists of TiALN (titanium aluminum nitride) or TiCN (titanium carbonitride) and has a rough surface.
  • This coating according to the invention ensures an excellent hydrophilic property of the roller.
  • a coating of this type improves the dampening solution guidance and increases the print quality.
  • a sufficiently thick and even dampening solution film is achieved, the alcohol content being eliminated or only being required to a small extent ( ⁇ 6%). The addition of alcohol or alcohol substitutes to the dampening solution can thus remain very low or be completely eliminated.
  • An intermediate layer can be applied to improve the adhesion between the base body and the outer coating. This intermediate layer is preferably made of matt chrome.
  • PVD Physical Vapor Deposition
  • the coated roller is not limited to dampening systems. Rather, it is also suitable e.g. for inking, coating units etc. where the problem of transporting and dosing flowable media has to be solved.
  • the outer coating 5 is arranged as a PVD hard material coating consisting of TiALN or TiCN with a hardness of approximately 1500 to 3500 HV and a layer thickness of 2 to 10 ⁇ m. According to FIG. 3, the outer layer 5 (TiALN or TiCN) is applied directly (without intermediate layer 4) concentrically to the base body 3 with a hardness of 1500-3500 HV and a layer thickness of 2-10 ⁇ m.
  • the present coating has very good wettability for dampening solution management.
  • the alcohol or alcohol substitutes are reduced to a small percentage or can be omitted entirely. This has the advantage that agents that are harmful to health and the environment can be reduced to an acceptable level or can be dispensed with entirely.
  • the ink / fountain solution balance can be adjusted more quickly and remains stable during the printing process
