Definitions

  • the invention relates to a printing blanket for flexographic printing.
  • a printing blanket usually has a multi-layer structure.
  • the outermost layer is the cover layer, the surface of which is aligned with the object to be printed and is used for ink transfer.
  • the relief to be printed can be incorporated into the cover layer using laser engraving, for example, so that raised areas of the cover layer can be formed to which the ink can adhere and be transferred to the surface of the object to be printed (relief printing process).
  • the printing blanket can have a first fabric layer as the first reinforcement layer, which can be used to regulate the conveying behavior in the printing machine as well as the dimensional stability in the height (thickness) and width of the printing blanket.
  • a compressible layer can be provided, which can regulate the hardness of the material of the printing blanket as well as its conveying behavior.
  • a second fabric layer can be present as a second reinforcement layer, which can be designed as a single or multi-layer fabric.
  • This second reinforcement layer can also serve to provide dimensional stability in height and width, as well as in the longitudinal direction, i.e. in the direction of rotation of the printing cylinder.
  • the fabric can be natural, i.e. made of natural fiber, synthetic, i.e. made of chemical or synthetic fiber, or hybrid.
  • the printing blanket can be attached to the smooth outside of the usually metallic printing cylinder by gluing.
  • an adhesive layer can be provided on the underside of the printing blanket, such as the inner surface of the second reinforcement layer, i.e. the inner side of the printing blanket facing the printing cylinder, which can create a material bond with the outside of the printing cylinder, i.e. the outer surface of the printing cylinder, when in contact.
  • This adhesive layer can usually be created using double-sided adhesive tape.
  • the disadvantage of using a fabric as a second reinforcement layer is that the fabric can lose thickness, i.e. collapse, under the load of use. This can be explained by the fact that the fabric fibers consist of filaments that can contain air pockets. This air can be pressed out of the fabric during the use of the printing blanket, which can compress the height of this second reinforcement layer and thus make it flatter.
  • the second reinforcement layer in this form can therefore have a lack of dimensional stability in height, i.e. in thickness.
  • the second reinforcement layer can have an uneven surface towards the adhesive layer due to its fabric structure, ie the filaments of the fabric can form a wavy surface. This can lead to only point-like contact between the raised areas of the fabric of the second reinforcement layer and the adhesive layer, which can weaken the adhesive strength between the adhesive layer and the rest of the printing blanket.
  • liquids such as For example, chemical printing inks used in printing can penetrate the porous fabric of the second reinforcement layer and cause it to swell, ie increase its thickness. This can occur particularly at the edges, which can lead to an uneven thickness of the printing blanket, which can impair the quality of the print.
  • the liquid absorbed into the fabric can also weaken the bond between the adhesive layer and the second reinforcement layer.
  • the EP 2 168 764 A2 describes a relief printing plate precursor for laser engraving comprising a relief-forming layer comprising a peroxide and a binder polymer and having a cross-linked structure.
  • the US 2007/190452 A1 describes a laser-imageable flexographic printing plate precursor comprising a thermosetting, irreversibly cured elastomeric top layer which is at least partially ablatable, a radiation sensitive compound and an ablatable thermosetting polymer derived by thermally crosslinking one or more thermally crosslinkable mono- or polyacrylate monomers or oligomers in the form of a paste and a non-ablatable elastomeric underlayer.
  • the WO 2014/199469 A1 describes a flexographic printing plate material comprising a printing layer for engraving containing rubber, a compression layer, a base fabric layer provided between the printing layer for engraving and the compression layer, and a reinforcing layer.
  • An object of the present invention is to provide a printing blanket for flexographic printing of the type described above, so that the adhesive bond between the printing cylinder and the printing blanket can be improved.
  • the present invention therefore relates to a printing blanket for flexographic printing.
  • the printing blanket has a cover layer for transferring an ink by means of a printing side.
  • the cover layer represents the outer layer towards the outside, which can absorb ink and transfer it to an object to be printed.
  • the term "printing blanket” can therefore mean both a cylindrical printing plate and a flat printing plate, depending on the application and type of printing process.
  • the ink transfer medium also has an adhesive layer for attaching the printing blanket to a substrate, in particular to a cylinder of a printing machine. This allows the printing blanket to be firmly bonded to the printing cylinder and thus held on it during operation, i.e. during printing, so that the cover layer or its printing side can take over its function.
  • the color transfer medium also has a carrier layer which is arranged between the cover layer and the adhesive layer. Further layers can be arranged between the cover layer and the adhesive layer. However, the adhesive layer is arranged directly on the side of the carrier layer facing away from the printing side, so that further layers can only be arranged between the cover layer and the carrier layer if necessary.
  • the carrier layer is a film which consists of or comprises a plastic material or a metal material. This is understood to mean a very thin layer in terms of height. Several plastic materials or metal materials can also be used in order to use their properties in combination.
  • the film is preferably made of a plastic material. This can simplify production.
  • This invention is based on the knowledge that the carrier layer made of plastic or metal can be produced without any air inclusions at all or without air inclusions that can break down during the operation of the printing blanket. In this way, the flexibility of the layer of the printing blanket to which the adhesive layer adheres can be avoided in height. This can lead to greater dimensional stability in height. The resulting longer service life of the printing blanket can lead to longer service lives and thus lower costs.
  • Another advantage here is that cavities in this layer can be avoided, into which liquids, particularly printing chemicals, can penetrate, which could then cause the printing blanket to swell. These liquids could also have a negative effect on the adhesive bond and reduce its effectiveness. Avoiding these problems can help to increase or maintain the print quality that can be achieved by using the printing blanket as a printing plate.
  • a plastic or metal film as a carrier layer can have a very high dimensional stability in the surface, i.e. in the width and in the longitudinal or circumferential direction of the cylindrical printing blanket (in the printing direction).
  • This is particularly advantageous with regard to engraving the cover layer, because the motif to be transferred engraved into the cover layer should have the highest possible positioning accuracy (register stability) and this can be promoted by a high dimensional stability of the printing blanket in the surface.
  • the dimensional stability of the printing blanket means that the material of the printing blanket has a high degree of rigidity at the working point or in the operating range, i.e. a high increase in force with a small amount of stretch. This is an elastic deformation (Hook's line), i.e. a linear relationship between force and stretch.
  • a double-sided adhesive tape can be used as the adhesive layer, which can be applied to the underside of the carrier layer.
  • the underside of the carrier layer can also have an adhesive layer applied to it.
  • the film has a surface with a roughness Rz of equal to or less than 10 ⁇ m opposite the adhesive layer.
  • Rz roughness
  • the film is a plastic film that consists of polyester or that contains polyester.
  • This material as a plastic can fulfill the properties mentioned above and thus bring about the advantages that can be achieved thereby.
  • polyester is inexpensive to manufacture and easy to process.
  • a carrier layer made of polyester can also bring about high dimensional stability in the surface, i.e. in the width and lengthwise direction.
  • the foil is a metal foil which consists of metal or which comprises metal.
  • the adhesive layer is arranged as a double-sided adhesive tape by winding it up.
  • This allows the adhesive layer to be applied easily and quickly on site, i.e. directly on the printing cylinder, to the printing blanket, so that the adhesive layer does not have to be applied beforehand and protected against drying out and/or contamination, which could represent additional effort. It is also possible to decide directly on the printing cylinder where and in what thickness the adhesive tape should be applied or arranged between the printing blanket and the printing cylinder.
  • the adhesive layer is arranged on the film by application.
  • the application can be carried out, for example, by spraying or wetting. This can preferably be done during the production of the
  • the printing blanket can be applied as the last step in the process.
  • the applied adhesive layer can then preferably be provided with protection against drying out and/or contamination.
  • the advantage here is that the printing blanket can be delivered to the printing company or similar together with the adhesive layer, so that the printing blanket can be applied to the printing cylinder directly or, if necessary, after removing a protective layer with the adhesive layer. This can simplify and speed up the application to the printing cylinder.
  • the ink transfer medium further comprises a reinforcement layer which is arranged between the cover layer and the carrier layer.
  • the reinforcement layer is arranged directly between the cover layer and the carrier layer.
  • the reinforcement layer can be used to regulate the conveying behavior in the printing machine as well as the dimensional stability in the height (thickness) and width of the printing blanket.
  • the ink transfer medium further comprises a compressible layer which is arranged between the cover layer and the carrier layer, preferably between the strength carrier layer and the carrier layer.
  • the compressible layer preferably has a compressibility of more than 150 ⁇ m at a load of 135N/cm ⁇ 2.
  • the compressible layer is preferably arranged directly between the cover layer and the carrier layer or directly between the strength carrier layer and the carrier layer.
  • the compressible layer can be used to regulate the hardness of the material of the printing blanket and its conveying behavior.
  • the cover layer consists of an elastomeric material or has an elastomeric material.
  • the advantage here is that the cover layer can be easily engraved in this way.
  • Fig.1 shows a side schematic sectional view of an ink transfer medium 1 according to the prior art.
  • the ink transfer medium 1 is a printing blanket 1 which, in the flatly spread-out state, e.g. after production or when cutting, extends in a horizontal plane in a longitudinal direction Y and a transverse direction (not shown).
  • the height Z or thickness Z extends perpendicular to this. If the printing blanket 1 is cut and applied to a printing cylinder (not shown), the longitudinal direction Y becomes the circumferential direction Y, in which the printing blanket 1 is arranged around the cylindrical circumference of the printing cylinder as a printing plate 1.
  • the upper side of the printing blanket 1 represents the Fig.1 represents the top side of the printing blanket 1, which becomes the outside of the printing plate 1. Accordingly, the lower side of the printing blanket 1 in the illustration of the Fig.1 the underside of the printing blanket 1, which becomes the inside of the printing plate 1.
  • the printing blanket 1 of the Fig.1 has a cover layer 10, which can be referred to as cover plate 10 in the case of the printing plate 1.
  • the upper outer side of the cover layer 10 represents the printing side 11 of the cover layer 10, which can be used, for example, to form a relief by laser engraving.
  • the cover layer 10 preferably has a predetermined minimum thickness in order to provide sufficient material at the height Z, which allows the formation of sufficiently clear contours of the motif.
  • the cover layer 10 can have a thickness of at least 0.3 mm at the height Z.
  • a first reinforcement layer 12 in the form of a fabric layer 12 is arranged, which serves to regulate the conveying behavior in the printing machine as well as the dimensional stability in the height Z and in the width of the printing blanket 1.
  • the next layer is a compressible layer 13, which regulates the hardness of the material of the printing blanket 1 as well as its conveying behavior.
  • a second reinforcement layer 14 is provided as a second fabric layer 14, which also serves to provide dimensional stability in height Z and width as well as in longitudinal direction Y.
  • an adhesive layer 16 in the form of a double-sided adhesive tape 16 is arranged, via which the printing blanket 1 can be glued to the printing cylinder.
  • the second reinforcement layer 14 has a two-layer fabric, the filaments or threads of which alternately overlap one another. This creates point-like elevations at the height Z of both the compressible layer 13 and the adhesive layer 16, which surrounded by depressions or flatter areas at height Z. In this way, at least between the adhesive layer 16 as double-sided adhesive tape 16 and the second reinforcement layer 14, there are only point-like material contacts, which weakens the adhesive effect between these two layers 14, 16. Hollow spaces also form in the second reinforcement layer 14, which can absorb air, the escape of which over the duration of the operation of the printing plate 10 can weaken the dimensional stability of the printing plate 1 at height Z. Liquids such as printing chemicals can also penetrate into these hollow spaces and cause the second reinforcement layer 14 to swell.
  • Fig.2 shows a side schematic sectional view of a color transfer medium 1 according to an embodiment of the present invention.
  • a carrier layer 14 made of polyester is arranged between the compressible layer 13 and the adhesive layer 16.
  • air inclusions can be avoided, so that a higher dimensional stability of this layer 15 can be achieved in the longitudinal direction Y, in the transverse direction and in the height Z.
  • hollow spaces can also be avoided into which printing chemicals could penetrate. This leads to better printing quality and a longer service life of the printing blanket 1 according to the invention.
