Definitions

  • the invention relates to a method for imaging printing plates according to the Preamble of claim 1.
  • JP 101 19 230 A discloses a method for producing a printing plate.
  • this Printing plate lies the ink-accepting layer, i. H. the printing layer on which water-accepting layer.
  • the ink-accepting Layer sprayed with an imaging material using an ink jet so that the not printing areas become water-soluble.
  • the invention has for its object a method for imaging To create printing plates.
  • the advantages that can be achieved with the invention are, in particular, that with one Ink-jet printing unit on the ink-repellent layer corresponding to one to be printed A developing liquid is applied with which the ink-repellent layer is deposited the sprayed area is dissolved or dissolved and the dissolved or dissolved areas the ink-repellent layer can be removed.
  • different printing plates can be used.
  • a waterless printing plate with an ink-repellent layer made of silicone Preferably however, in particular a waterless printing plate with an ink-repellent layer made of silicone.
  • Different layers are used as the ink-accepting layer Consideration that withstand the developing liquid for the ink-repellent layer, in particular, a polyethylene film can be provided lying under the silicone layer.
  • the developing liquid used is expediently applied to the layer to be resolved.
  • a solvent is used with where the corresponding areas of the ink-repellent layer are liquefied.
  • the silicone layer can be loosened in a subsequent step Areas can be removed particularly easily.
  • the other or resolved areas with the first printing ink or with a suitable one Cleaning unit can be removed mechanically.
  • the on or resolved areas of the top layer of the printing plate by mechanical Stress on the printing plate, in particular removed by a printing process. This minimizes the steps required for imaging and one efficient and simple printing plate imaging achieved.
  • the printing plate 01 shown in FIG. 1 has a carrier layer or a substrate 02 which Can be made of aluminum and has a suitable thickness to the desired to achieve mechanical properties.
  • a color-accepting Layer 03 On it are applied a color-accepting Layer 03 and overlying it a color-repellent layer 04.
  • the ink-accepting layer Layer 03 can be formed as a polyethylene film. Their thickness can range from 5 - 50 microns, preferably it can be about 20 microns.
  • the color-repellent Layer 04 is made of silicone. Their thickness is chosen appropriately. You can in the area a few ⁇ m, in the embodiment shown it is about 2 ⁇ m.
  • Between the Substrate 02 and the ink-accepting layer 03 can be an adhesive or primer layer lie. In the exemplary embodiment shown, a titanium oxide layer is provided.
  • a waterless printing plate from Presstek (PearlDry) is preferably used, as described in US 54 87 338 A, on the structure of the Printing plate is expressly referenced.
  • the control of the print head 05 is done in the usual way for inkjet printers. That corresponds to the Solvent applied to the printing image liquefies the silicone in the areas in to which it is applied so that the silicone can easily be removed in these areas can be. Instead of liquefaction, only a change in the Properties of the silicone layer 04, z. B. by swelling or reducing the Hold to the underlying layer.
  • the dissolved silicone layer 04 or their separated areas can be with the first color or a suitable one Cleaning unit to be continued. It is advantageous here that the dissolved silicone as Liquid is present.
  • the liquefied silicone can by mechanical Stress of a printing process can be removed.
  • the already illustrated printing plate with the removed areas of the silicone layer 04 is in Fig. 2 shown.
  • the printing plate 01 is brought into contact with printing ink that is only on the ink-accepting polyethylene layer 03, d. H. in the areas where the Silicone layer 04 was removed, remains stuck. Accordingly, the illustration of the Transfer the printing plate to the carrier to be printed.
