Definitions

  • the invention relates to a process for the production of a rubber blanket for inline coatings with an aqueous-based dispersion coating or, in conjunction with UV coating-resistant rubber blankets, also for the application of low-viscosity UV coating in rotary printing machines according to the preamble of the first claim.
  • the object of the invention is to find a method by means of which, instead of the color swatch, the areas to be kept free of the paint application can be located on a rubber blanket.
  • the advantage of the invention is that set-up times are reduced because the areas that are not to be painted can be rationally located in advance on the rubber blanket (lacquered blanket), which previously was not possible. This is the first time that a reference copying process has been found on offset rubber blankets.
  • printing plates can be clamped on forme cylinders with painting options in conjunction with a dual-purpose tensioning rail for optional tensioning of a rubber blanket or a printing plate with one or more self-adhesive rubber blankets, and thus a recessed inline coating can be carried out.
  • Blankets that were previously used for printing and are now to be used for painting can be attached to aluminum offset plates with adhesive or double-sided adhesive material.
  • the adhesive must not be soluble in water.
  • the rubber blanket surface must be made grease-free with solvent cleaners even before opening, and paint residues and the like must be removed. If the rubber blanket surface of the drawn-on cloth repels pearly water, an approx. 10% phosphoric acid solution is to be applied before cleaning with chalk, which should take effect for about 2 minutes. Then rinse again with water.
  • a soft, hardly damp viscose sponge should only be used for the application of the copy layers. Wiping marks cannot be avoided when applying the copying layers with the sponge. However, these are of no importance for a reference copy.
  • an adhesive strip to be cut out e.g. as a hardened, colored layer or as a developed section.
  • Exposure example 5,000 watt metal halide lamp, distance 1 m, approx. 90 seconds, depending on the color of the blanket surface.
  • the polyvinyl alcohol copying layers are undyed layers, so that the color change due to the exposure is not very great. Even the use of layers that have already been colored before coating does not provide a clearly visible contrast due to the strong inherent color of the substrate.
  • the rubber blanket can either be placed on an aluminum printing plate, i.e.
  • a metal carrier can be attached using an adhesive or a double-sided adhesive film, or a self-adhesive rubber blanket or several parts that can be purchased can also be glued directly onto a suitable carrier plate.
  • Coating and copying onto a rubber blanket tensioned with the same force as is required for tensioning a rubber blanket on a rubber blanket cylinder is also suitable.
  • copying templates when coating on a flat, neither stretched nor glued-on blanket, copying templates can be used which extend in the circumferential direction, i.e. Direction of travel of the printing material through the printing machine, reduced by as much as percent in the circumferential direction, as the stretching of the rubber blanket used for varnishing when stretching on the cylinder is between 1 and 3% depending on the type of blanket.
  • wipe-on copying layers are also suitable. These copy layers are only wiped onto the cleaned, dry surface with a sponge, they are not spun or poured.
  • the wipe-on copy layer works with diazo salts and not with bichromate as a light-sensitive component.
  • a coating developer is used to develop the exposed layer.
  • Wipe-on copy layers or paint developers are e.g. known as the "Neganol process". With this copying process a reference copy on blanket surfaces is also possible.
