Definitions

  • the present invention relates to an intaglio printing plate with a polymeric printing layer applied to a dimensionally stable, flexible support, which is suitable for clamping onto an intaglio clamping cylinder.
  • the invention further relates to a method for producing such an intaglio printing plate.
  • rotogravure plates are generally clamped onto a cylinder base body using a suitable clamping device.
  • clamping cylinders with a cylinder channel with means for fastening and clamping the pressure plates are known and are also described in the literature (cf. e.g.
  • One problem here is the gap that forms at the abutment points of the pressure plate when it is clamped.
  • the squeegee which is aligned parallel to the cylinder axis, from being pressed into the gap and the squeegee from jumping and thus damaging the squeegee and the printing layer.
  • the present invention was based on the object of producing in a simple manner an intaglio printing plate with a plastic printing layer, which can be easily and easily clamped onto intaglio clamping cylinders without forming an annoying gap.
  • intaglio printing plates can be produced simply if, in the case of an intaglio printing plate, the polymeric printing layer, which is applied firmly to a dimensionally stable, flexible support, is removed from the support in the areas of the intaglio printing plate , removed, which are used to attach the plate to the clamping cylinder and have to be folded over for this.
  • the invention accordingly relates to a process for producing intaglio printing plates with a polymeric printing layer applied to a dimensionally stable, flexible support for mounting on an intaglio printing clamping cylinder, which is characterized in that the polymeric printing layer is removed from the areas of the support to be edged for mounting .
  • the invention further relates to the gravure printing plates produced in this way, suitable for clamping onto a clamping cylinder, in which the support is free of the polymeric printing layer in the areas to be folded over for clamping.
  • the invention furthermore relates to special embodiments of the method and the intaglio printing plates as described below.
  • the rotogravure plates according to the invention can be easily and easily attached to the conventional rotogravure clamping cylinders.
  • the polymeric printing layer in these intaglio printing plates extends only over the actual printing area corresponding to the cylinder circumference.
  • the edges of the polymeric printing layer are firmly and flush butted and pressed so that an almost joint-free surface without an annoying gap, which is formed during printing, is formed.
  • the polymeric printing layer has a layer thickness in the range of about 100 to 500 / um has since then a particularly good gap closure is achieved in the inventive intaglio printing plates.
  • the edging line running across the width of the printing plate can run perpendicular to the long sides of the printing plate and thus, after clamping, parallel to the cylinder axis;
  • these fold lines, up to which the polymeric printing layer is removed from the carrier run somewhat obliquely to the cylinder axis, ie not exactly perpendicular to the long sides of the printing plate.
  • the supports for the rotogravure plates according to the invention which are known and known per se are dimensionally stable and flexible support materials, in particular plate-shaped steel or aluminum sheets, but also, if appropriate, suitable plastic films.
  • the polymeric printing layer, which is applied to the support in an adherent manner, for example by means of a suitable adhesion promoter, can be a simple plastic layer, as is described, for example, in DE-OS 27 52 500, into which the ink-receiving depressions are mechanically engraved.
  • this printing layer is preferably a photopolymeric layer which is obtained by imagewise exposure and development of a photopolymerizable layer of a mixture of a polymeric binder, and thus compatible photopolymerizable, ethylenically unsaturated Monomers and / or oligomers and a photoinitiator has been generated (cf. DE-OS 20 54 833, DE-OS 20 61 287, DE-OS 3 128 949 and DE-OS 31 28 951).
  • the removal of the polymeric printing layer from the areas of the carrier that are to be folded over for fastening on the tensioning cylinder is advantageously carried out before the actual folding and can be done mechanically, for example, by cutting, milling or engraving.
  • the rotogravure plates according to the invention can be produced particularly easily and simply, in particular with the required accuracy and precision, if one starts from a light-sensitive recording material with a photopolymerizable layer of the type mentioned and described above adhered to a dimensionally stable, flexible support.
  • the photosensitive recording materials as described in DE-OS 31 28 949, to which reference is made here for details on the composition of these recording materials and on the production of gravure forms, have proven to be very advantageous.
  • the intaglio printing plates according to the invention are produced by means of these light-sensitive recording materials by, in a manner known per se, the photopolymerizable layer for producing the printing layer by means of a suitable template, for example by means of a screen or line positive or a halftone positive with a guide screen. is exposed imagewise with actinic light and with the formation of the grid and cell structure, the unexposed portions of the layer with the aid of a suitable developer liquid, in which the unexposed portions, but not the exposed portions of the layer are soluble, washed out and removed.
  • the exposure of the photopolymerizable layer is carried out in such a way that the photopolymerizable layer remains unexposed in the areas later to be folded over for clamping the printing plate, so that the photopolymeric layer in these areas when washed out with the developer liquid is removed at the same time as the remaining unexposed portions of this layer.
  • the exposure of the photopolymerizable layer is preferably carried out via a register in this embodiment of the method according to the invention. An intaglio printing plate according to the invention is thus obtained directly, in which the areas of the support to be folded over for clamping onto the tensioning cylinder are free of the polymeric printing layer.
