Definitions

  • the invention relates to a surface structure carrying substrates, preferably for printing press cylinders or their elevators.
  • the surface structure is particularly suitable on a impression cylinder of an offset sheet-fed rotary printing machine for perfecting.
  • DE 2 446 188 C3 discloses a surface made of statistically uniformly irregularly distributed convex and concave elevations and depressions of an elevator.
  • the spherical dome-shaped structural elements are designed so that the substrate, e.g. an arch, trimmed.
  • a surface structure for a sheet-guiding film as an elevator for impression cylinders is known, which has spherical caps as a carrier layer, which additionally has a cover layer (coating) made of chromium or nickel or chromium-nickel steel.
  • an arc-guiding surface structure preferably for a printing cylinder, which has cylindrical elevations.
  • the cylindrical elevations made of chrome are arranged perpendicular to the surface of the cylinder and with their cover layers parallel to the cylinder axis.
  • a disadvantage of these structures is that they have relatively smooth surfaces. These smooth surfaces are desirable because they have good ink release properties.
  • the object of the invention is to develop a surface structure which ensures a noticeably better sheet guidance by increasing the frictional forces at the contact points of the printing material and surface structure in order to noticeably reduce the appearance of doubling.
  • all previously known advantages are to be maintained.
  • the surface structure achieves improved static friction in the contact between the substrate and the wings. This results in an increase in quality, especially in face and reverse printing, since the appearance of duplication is noticeably reduced.
  • the surface structure continues to favor the ink release behavior.
  • the surface structure can have spherical cap, cylindrical, truncated cone or truncated pyramid shaped structural elements, wherein a concatenation of the structural elements is also possible.
  • the surface structure carrying the substrate is arranged on the circumference of a impression cylinder of a sheet-fed offset printing press.
  • the impression cylinder is preceded by a turning device which transfers the sheet to the impression cylinder according to the principle of trailing edge turning.
  • the surface structure consists of a hard chrome layer 1, which is applied to a substrate 3.
  • the substrate 3 is the outer surface of the impression cylinder.
  • this can also be another printing press cylinder or an elevator for this.
  • the hard chrome layer 1 has a thickness of 150 ⁇ m, for example.
  • the surface structure is composed of statistically approximately uniformly distributed, elevated structural elements 2 with correspondingly assigned structural valleys 6.
  • the raised structural elements 2 are approximately cylindrical (FIG. 1), spherical cap (FIG.
  • the structural elements 2 can also be designed as a truncated pyramid.
  • the structural elements have wings 4, which in with the printed sheet Stand in contact by the arch is supported on these wings 4 upon contact with the impression cylinder. These wings 4 are arranged approximately at the same height.
  • the hard chrome layer 1 has a multiplicity of irregularly more or less large depressions 5, which are enlarged on the structural elements 2 in comparison to the structural valleys 6. These depressions 5 are enlarged column-like or furrow-shaped, in particular on the wings 4.
  • the structural elements 2 have a roughness value of R 2 15 to 35 ⁇ m. The depressions 5 are thus so deep in the hard chrome layer 1 that a sufficiently corrosion-resistant chrome layer remains on the substrate 3.
  • the printed side of the sheet transferred from a turning device to the impression cylinder comes into contact with the surface structure, especially the wings 4.
  • the wings 4 with their depressions 5 take over the function of arch guidance.
  • the color is split back from the wings 4 on the sheet or on subsequent sheets.
  • the surface structure according to the invention thus significantly improves the print quality.
  • the structural elements 2 can have an additional coating.
  • PVD Physical Vapor Deposition
  • the PVD layer can consist of titanium nitride and have a layer thickness of 3 ⁇ m.
  • the structural elements 2 and the structure valleys 6 with the depressions 5 are not influenced in their surface roughness.
