Definitions

  • the invention relates to a method for embossing structures with dimensions in the range of micrometers or nanometers in a lacquer layer made from a lacquer, the lacquer layer being applied to one side of a film web and being curable by means of ultraviolet radiation.
  • the foil web is first pressed in the direction of transport with the side on which the not yet hardened layer of lacquer is located, by a pressure roller against an embossing cylinder, on the surface of which the structures to be embossed in the micro or nanometer range are located.
  • the structures in the micro or nanometer range form in the paint layer.
  • the paint layer is cured by ultraviolet radiation from an ultraviolet radiation source.
  • a method of this type has already been used for many years, with the film web being guided to the embossing cylinder from below or at least diagonally from below.
  • Part of the lacquer of the lacquer layer that has not yet hardened accumulates in the conveying direction immediately in front of the point at which the lacquer layer touches the embossing cylinder and forms a so-called "lacquer wedge".
  • this lacquer wedge is unevenly distributed, with both the thickness of the wedge and its distribution changing constantly and unpredictably in the direction of the axis of rotation of the embossing cylinder.
  • the geometric shape and distribution of the paint wedge is therefore stochastic, which results in an uneven distribution of the paint layer on the film web, which is particularly disadvantageous.
  • the structures in the micro or nanometer range are thus embossed in an unevenly distributed layer of paint, with an unevenly thick and in the horizontal direction, based on UV radiation, even after the embossing and subsequent curing of the layer of paint the film web, results in an unevenly distributed layer of lacquer with embossed structures in the micro or nanometer range.
  • a method for producing a security element which consists of two components. Both components must be arranged in exact register or register with one another, with an adjustable stretching roller being provided to maintain or set this register.
  • the second components of the security element are preferably produced by an embossing unit.
  • WO 2011/020727 A1 discloses a method of producing an optically variable image in which an epoxy paint for application to a web can be heated, thereby reducing its viscosity. By the time of the subsequent embossing process, the viscosity of the lacquer will have changed or increased again as a result of cooling.
  • the invention is therefore based on the object of further developing a generic method in such a way that the disadvantages of the prior art are eliminated.
  • the film web is guided to the embossing cylinder from above or at least diagonally from above.
  • the part of the lacquer of the not yet hardened lacquer layer which builds up in the conveying direction immediately in front of the point at which the lacquer layer touches the embossing cylinder, becomes a larger wetted area on the surface of the embossing cylinder.
  • the paint wedge of the method according to the invention is not unevenly distributed and its geometric shape and distribution are not pronounced stochastically.
  • the reason for the larger wetted area on the surface of the embossing cylinder in the method according to the invention is that the gravitational force leads the lacquer layer to the point at which the film web touches the embossing cylinder in addition to the direction of movement of the film web.
  • the lacquer layer is pulled away from the embossing cylinder by the force of gravity.
  • Another advantage of the invention is that the larger wetted area on the surface of the embossing cylinder increases the time it takes for the air to escape from the embossing structures on the surface of the embossing cylinder, so that the layer of lacquer can be removed at higher speeds of the film web and with the same number of air bubbles in the embossed lacquer layer or alternatively at the same speed of the film web but with a reduced number of air bubbles in the embossed lacquer layer.
  • the impression roller is pressed against the embossing cylinder with high mechanical pressure, so that a clearly recognizable amount of lacquer of the lacquer layer is squeezed.
  • the width of the lacquer layer after embossing is no longer identical to the width of the lacquer layer in front of the embossing cylinder, but wider.
  • the width of the varnish is 620 mm before embossing and 720 mm after embossing.
  • a film web consists, for example, of polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polypropylene (PP) or polycarbonate (PC) with a thickness for security threads or security films of preferably 8 ⁇ m to 36 ⁇ m, for banknotes made of polymer or for film composite banknotes up to 100 ⁇ m or for card bodies up to 200 ⁇ m.
  • PET polyethylene terephthalate
  • PEN polyethylene naphthalate
  • PP polypropylene
  • PC polycarbonate
  • the thickness of the lacquer layer is preferably from 0.5 ⁇ m to 20 ⁇ m, particularly preferably from 4 ⁇ m to 15 ⁇ m and very particularly preferably from 4 ⁇ m to 8 ⁇ m.
  • the lacquer layer is preferably applied to the film web by means of a flexographic printing process.
  • the film web is deflected by a deflection roller and guided onto the embossing cylinder, with the deflection roller being arranged in front of the impression roller in the direction of transport.
  • the film web can be guided away from the embossing cylinder again by a second deflection roller.
  • the first and possibly second deflection roller ensures that the lacquer layer wraps around the embossing cylinder over a larger peripheral surface.
  • the film is fed onto the embossing cylinder vertically or at least almost vertically from above or in the direction of the weight force or almost in the direction of the weight force becomes.
  • At least obliquely from above in the context of this invention means that the foil is fed onto the embossing cylinder from above at an angle in a range from more than horizontal to almost vertical, with the foil in particular not being fed horizontally onto the embossing cylinder.
  • Such structures with dimensions in the range of micrometers or nanometers are used in particular to increase the counterfeiting protection of documents of value, in particular banknotes, shares, bonds, certificates, vouchers, checks, high-quality admission tickets, but also other papers at risk of counterfeiting, such as passports and other identification documents, as well as Cards, such as credit or debit cards, and also product security elements, such as labels, seals, packaging and the like.
  • the structures with dimensions in the micrometer or nanometer range are, for example, diffractive structures, micromirrors, matt structures or moth-eye structures.
  • FIG. 1 shows a side view of an embossing process known from the prior art.
  • a lacquer layer 6 on a film web 5, the film web being fed in the direction of movement 7 obliquely from below onto an embossing device.
  • the embossing device consists of an embossing cylinder 1, in the surface of which structures to be embossed with dimensions in the range of micrometers or nanometers are introduced, a roller-shaped impression roller 2, a source 4 for ultraviolet radiation and two deflection rollers 3.
  • the film web 5 is through the first deflection roller 3 deflected in such a way that the lacquer layer 6 comes into contact with the embossing cylinder.
  • part of the not yet hardened lacquer layer builds up and forms the unevenly shaped lacquer wedge 8.
  • the film web 5 together with the lacquer layer 6 is then pressed against the embossing cylinder 1 by the impression roller 2 and the structures with dimensions in Area of micrometers or nanometers molded into the paint layer 6.
  • the lacquer layer 6 is then hardened by electromagnetic radiation in the ultraviolet wavelength range from the source 4 and guided away from the embossing cylinder 1 via a second deflection roller 3 and fed to subsequent processing steps.
  • the film web 5 is fed to the embossing device at an angle from above.
  • the film web 5 is deflected by the first deflection roller 3 in such a way that the lacquer layer 6 comes into contact with the embossing cylinder.
  • part of the not yet hardened lacquer layer builds up and forms the above-described and particularly advantageously uniformly shaped lacquer wedge 9 the structures with dimensions in the range of micrometers or nanometers are molded into the lacquer layer 6.
  • the lacquer layer 6 is then hardened by electromagnetic radiation in the ultraviolet wavelength range from the source 4 and guided away from the embossing cylinder 1 via a second deflection roller 3 and fed to subsequent processing steps.
