Definitions

  • the invention relates to a printing form. Furthermore, the invention relates to a printing unit of a printing press.
  • Printing form-based printing processes include screen printing, high-pressure, planographic printing and gravure printing, with offset printing in particular being to be expected for lithographic printing.
  • the present invention relates to the field of printing form-based printing processes, in particular the planographic printing processes, which work with erasable and rewritable printing forms.
  • the EP 1 118 470 B1 Figure 1 relates to a printing method with a reusable printing form in which a coating consisting of a hydrophobic thermoplastic material and a hydrophilic binder is applied to a hydrophilic substrate.
  • This applied coating is irradiated imagewise, whereby in the irradiated areas the thermoplastic material fuses with the hydrophilic surface and forms image areas. The unirradiated areas are removed during the printing process, at which point the hydrophilic substrate is uncovered.
  • a rewritable and erasable printing plate for planographic printing which is designed as a lithographic printing plate.
  • the lithographic printing plate disclosed therein has a photoconductor wherein the entire surface of the photoconductor is charged by a charger, and then the photoconductor is exposed to the information to be printed. In the exposed areas of the photoconductor, the charges flow off. In the non-exposed areas, the charges remain on the surface of the photoconductor. The photoconductor then carries a charge image corresponding to the printing information and is brought into contact with printing ink and fountain solution.
  • the fountain solution wets the surface of the photoconductor and the ink can not accumulate.
  • the ink for the image to be printed is deposited in the charge-free regions of the photoconductor.
  • a charging device which generates a homogeneous charge distribution and an exposure device which generates the charge image are required. This also requires a high process engineering effort.

  • the present invention proposes a printing form in which the imaging takes place by applying different electrical voltages to the conductive surface elements of the printing form.
  • the imaging takes place without any material transport alone by applying the different electrical voltages. Therefore, no material has to be removed from the printing plates for deletion. Furthermore, no special charging devices and exposure units are required, so that ultimately the imaging and de-imprinting of the printing form according to the invention can be carried out with very low process outlay.
  • the dielectric functional layer has a dielectric constant greater than or equal to 2 and a thickness less than or equal to 100 microns, wherein the same is formed in particular of a plastic or a ceramic material or a carbon-based material or coated with such a material.

  • a two-dimensional array of conductive surface elements 13 is arranged under a relatively thin dielectric functional layer 12, wherein the surface elements 13 are preferably designed as controllable electrodes, to each of which a switching element 14 is assigned.
  • An individual electrical voltage can be applied to each of the surface elements 13, so that an individual electric field is formed between the respective surface element 13 and the counterelectrode 15.
  • the surface property, namely surface energy or surface tension, and thus wetting capability of the region of the dielectric functional layer 12 opposite the surface elements 13 can be influenced via the electric field so as to form the ink-carrying regions and non-ink-conducting regions of the printing form in the sense of imaging the same.
  • the carrier layer 11, the dielectric functional layer 12 and the surface elements 13 arranged between the carrier layer 11 and functional layer 12 and switching elements 14 in the sense of a pressure plate or a pressure sleeve as an integral component, which is then positioned on a forme cylinder of a printing unit.
  • the dielectric functional layer 12 it is also possible to design the dielectric functional layer 12 as a separate component, so that it can be separated from the other components of the printing forme, namely the carrier layer 11, the surface elements 13 and switching elements 14 in order to clean or to optionally clean it replace.
  • the carrier layer 11, the surface elements 13 and switching elements 14 into the surface of a forme cylinder.
  • both printing ink and dampening solution are applied to the printing plate by means of applicator rollers, so that an ink-dampening solution emulsion is formed on the surface of the printing form, namely on the dielectric functional layer 12 thereof.
  • an individual electric field forms between the surface elements 13 and the application rollers serving as the counterelectrode 15 in order to define the areas of the printing form in which the printing ink and in which Moisturizer accumulates.

  • the distribution of the ink in the ink-carrying areas of the printing plate is not spontaneous, but requires the support of the pressing forces in the transfer nip between the printing plate and the applicator rollers or the transfer cylinder, at the same time the times in which there is also the electric field, which forms the ink-carrying and the non-ink-carrying areas.
  • the new printed image is formed within a relatively short rewetting phase.
  • the size of the non-ink-conducting or ink-conducting regions of the dielectric functional layer 12 can then be defined in the sense of an amplitude-modulated screening in order to be able to reproduce semitones for greater differentiation of a printed image to be printed.

Since there is the danger of the formation of so-called moiré effects in multicolor, autotypic compression printing, as can be seen from a comparison of FIGS. 3 and 4, the arrays of surface elements 13 have a different angle.
  • rows of surface elements 13 extend parallel to a longitudinal direction of the printing form defined by the straight line 22.
  • Fig. 4 close the rows of surface elements 13 with respect to the line 22 a relatively acute angle. If printing plates with a correspondingly different angle of the second-dimensional arrays of the area elements 13 are used on the printing units involved in the autotypical compression, moiré effects impairing the print quality can be avoided.
  • the distance between the centers of adjacent surface elements 13 is preferably less than or equal to 1 mm, in particular less than or equal to 200 microns.
  • the printing form 10 according to the invention is preferably used in planographic printing, namely in offset printing, in which case application rollers of an inking unit, application rollers of a dampening unit and the transfer cylinder form counterelectrodes for the surface elements 13 of the printing form 10.
  • a printing press on whose printing units the printing form according to the invention is to be used must have a control device in order to control the individual surface elements 13 of the printing form 10 with corresponding electrical voltages. Then, when a printing press uses the printing form according to the invention, no printing form needs to be changed to change a printed image. To change a print image or to delete and re-imaging of the printing form, only the control of the surface elements must be changed with electrical voltages.
  • the switching elements 14, which serve to control the surface elements 13 designed as electrodes are integrated in the printing form 10.
  • the switching elements 14 for controlling the surface elements 13 are located outside the printing form.
