Definitions

  • the invention relates to a plate or form cylinder of a rotary-particular offset printing machine according to the preamble of claim 1.
  • the plate or form cylinder can be used as a support or receiving element of a plate-shaped, in a rounded form in axially extending clamping channels fixed, or a sleeve-shaped and can be pushed in this form printing form especially in offset printing, but is not limited thereto.
  • the printing unit can look like a classic offset printing unit with plate or form cylinder, i. Printing form, blanket and impression cylinder.
  • the printed image is known to be transferred from the plate cylinder to the blanket cylinder and from there to the paper passing over the printing cylinder.
  • the transfer of color, both from the plate to the blanket, as well as the blanket on the paper is only possible if a certain minimum pressure, the so-called line pressure between blanket and plate, or forme cylinder, is present.
  • the printing forme cylinder (ie the printing forme) thus provides the desired function permanently, ie a constant print quality, only when the job is correctly arranged (provided). Too little employment leads due to the tolerances of concentricity and cylindricity to a non-uniform ink or dampening agent transport. Too high employment adversely affects the life of the cylinder surface due to the internal friction and pressure overload.
  • the so-called channelless pressure in particular the sleeve technique, which is characterized by a printing plate applied seamlessly to a sleeve or a printing plate which is laser-welded to form a round shape, allows a reduced rigidity because of the reduced vibration excitation due to the missing cylinder channels.
  • the length / thickness ratio of the printing cylinder, or their relative stiffness with respect to a deflection becomes increasingly unfavorable.
  • the shape and position of the impression cylinders undesirably change from one another, i. that the impression cylinders bend.
  • the change in position due to deflection changes the pressure provision, i. the contact pressure between the pressure cylinders cooperating in the printing unit, which is seen over the cylinder width uneven. Determined in value numbers, this pressure provision is generally achieved by measuring the so-called impression width, i. the width of the zone that is set at each other, i. Pressed on cylinders defined the contact area of the cylinder. This measurement is particularly easy in offset printing, since always one cylinder of a pair of cylinders has a compressible (soft) surface.
  • the printing or transfer characteristic curve ie the dot gain, now depends directly on this impression width, wherein an increased impression width means increased dot gain and vice versa.
  • the effect described thus leads to an over the cylinder width considered undesirable changing pressure characteristic.
  • Fig. 4b shows the undesirable changes in position (deflection) of the two plate, or forme cylinder 1 of an offset printing unit for perfecting of Fig. 4a to each other during the printing operation.
  • the Anstelltik is unevenly over the cylinder width, i. The result is a line pressure, which is irregular over the cylinder width.
  • the plate, or forme cylinder of a rotary particular offset printing machine bend by the reaction forces of the blankets or rubber sleeves 10 in the center of pressure.
  • the blanket cylinder 11 bend slightly less than the plate or forme cylinder 1, since they are supported by the plate, or forme cylinder 1.
  • the pressure cylinder contour is pressed into the blanket, the surface load associated therewith causes a bending of the cylinder, resulting in a higher edge load and a much lower load in the middle of the cylinder.
  • the deflection of the printing form carrier can be determined based on theoretical calculations with known material parameters and area and line forces, for example by finite element calculation.
  • the surface 2 of the lateral surface of the plate or forme cylinder 1 in the axial direction rubdum in the circumferential direction with a convex profile, which was determined empirically or as indicated above calculated, made, ie designed spherical.
  • the shape curve 2 of the crown of the cylinder surface may be a circular arc or a parabola of at least second order. This means that the convex profile of the lateral surface 2 in the axial direction varies so that the diameter of the plate, or forme cylinder 1 is largest in the center of the axle and smallest at the lateral edges.
  • FIG. 2 shows that the transitions 3, 4 (radii) of the cylinder pit 5 are made correspondingly along the crowned cylinder surface 2, such that the pit width "s" remains constant over the axial length of the cylinder pit 5.
  • a printing plate 6 to be used in a plate cylinder according to FIG. 2 is designed in this way; that the bending length of the leading pressure plate radius 7 and trailing pressure plate radius 8 in the middle of pressure I center , as shown in Fig. 3b, is bent longer than at the pressure edges, so that the length at the pressure edges I edge shorter than the length in the middle I Middle is.
  • the trailing pressure plate radius 8 describes a shape curve 9, which must harmonize with the shape curve 2 of the surface of the plate cylinder 1.
  • Fig. 5 in comparison to Fig. 4b, is not only the contact between the blanket cylinder 11 and plate or by the inventive crowned design of the surface of a plate or forme cylinder 1 by means of a convexly curved surface in the axial direction
  • Form cylinder 10 improves, but also the contact between the two blanket cylinders 11 positively influenced.
