Definitions

  • the invention relates to a device for producing security elements, wherein the security elements are arranged on a front side and a rear side of a film web and consist of embossed structures in a lacquer layer with dimensions in the range of micrometers or nanometers.
  • the device has a device for providing a substrate, in particular a paper substrate, a first film application device for applying a first film element to a first substrate side and a second film application device for applying a second film element to a second substrate side.
  • the first film application device and the second film application device are arranged such that the first film element and the second film element are applied to the opposite sides of the substrate without turning the substrate.
  • the application of a film element is not comparable to the application of a lacquer layer on one side of a substrate in the form of a film web and the subsequent introduction of embossed structures with dimensions in the range of micrometers or nanometers. Rather, the application of a lacquer layer and the subsequent introduction of embossed structures requires other technical means and a different technical approach.
  • the document EP 1 720 079 A1 discloses a device for producing security elements, wherein the security elements are arranged on a back side of a film web and consist of embossing structures in a lacquer layer with dimensions in the range of micrometers or nanometers, wherein the device in the conveying direction of the film web comprises the following devices: a device for Providing a film web; a first printing unit for applying a first lacquer layer, which is curable by means of ultraviolet radiation, on the back of the film web, wherein the film web enters from below into the first printing unit; on first embossing unit for embossing first structures with dimensions in the range of micrometers or nanometers into the first lacquer layer, wherein the film web enters from obliquely upwards into the first embossing unit.
  • the invention is therefore the object of developing a generic method such that the disadvantages of the prior art are eliminated.
  • the first aspect of the invention differs from the second aspect only in that the directions of the inlet of the film web in each case invert to the printing or embossing works.
  • the film web runs in the first printing unit from below or obliquely down, in the first embossing from above or obliquely above, in the second printing unit also from above or obliquely above and in the second embossing again from below or obliquely down, whereas in the second aspect, the film web in the first printing unit from above or obliquely above, in the first embossing from below or obliquely down, in the second printing unit also from below or obliquely down and in the second In turn, embossing mill enters from above or diagonally upwards.
  • the film web is first pressed in the conveying direction with the side on which the not yet cured paint layer, by a impression roller to an embossing cylinder on the surface of which are to be embossed structures in the micro or nanometer range.
  • the structures in the micrometer or nanometer range are formed into the lacquer layer.
  • the resist layer is cured by ultraviolet radiation from a source of ultraviolet radiation.
  • From above in the sense of this invention means that the film web is fed perpendicularly or at least almost vertically from above or in the direction of the weight force or almost in the direction of the weight force on an embossing cylinder of a stamping mill or a printing cylinder of a printing unit.
  • At least obliquely from above in the sense of this invention means that the film web is fed at an angle in a range of more than horizontal to almost perpendicular from above on the embossing cylinder or the printing cylinder, the film web in particular not horizontally on the embossing cylinder or the Pressure cylinder is supplied.
  • From below in the sense of this invention means correspondingly that the film web is fed perpendicular or at least almost vertically from below or against the direction of gravity or almost against the direction of gravity on an embossing cylinder of a stamping or a printing cylinder of a printing unit.
  • At least obliquely from below in the context of this invention means that the film web is fed at an angle in a range of more than horizontal to almost perpendicular from below onto the embossing cylinder or the printing cylinder, wherein the film web in particular not horizontally on the embossing cylinder or the Pressure cylinder is supplied.
  • front side or back side of the film web are relative terms, which may also be referred to as “the one" and “the opposite” side, and which constitute the overwhelming portion of the overall surface of the film web. Specifically not included with these terms are the side surfaces of the film web, which are at a thickness of the film web, which is only fractions of a millimeter in card bodies or banknotes only fractions of a millimeter, are negligible and are usually not provided with security elements or coatings or can.
  • the film web is guided from above or at least obliquely from above to the first or second embossing cylinder. It has surprisingly been found that the part of the lacquer of the not yet cured lacquer layer, which accumulates in the direction of transport immediately before the point at which the lacquer layer touches the embossing cylinder and forms a so-called "paint wedge" there, to a larger wetted surface on the surface of the embossing cylinder leads.
  • the paint wedge of the device according to the invention is also not distributed unevenly and its geometric Form and distribution are not stochastically pronounced.
  • the reason for this 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 in addition to the direction of movement of the film web to the point at which the film web contacts the embossing cylinder.
  • the lacquer layer is pulled away from the embossing cylinder by the gravitational force.
  • Another advantage of the paint wedge is that due to the larger wetted surface on the surface of the embossing cylinder, the time for the escape of air from the embossing structures on the surface of the embossing cylinder increases, so that the paint layer at higher speed of the film web and the same number of air bubbles in the embossed lacquer layer or alternatively at the same speed of the film web but reduced number of air bubbles can be embossed in the embossed lacquer layer.
  • Such structures with dimensions in the range of micrometers or nanometers are used in particular for increasing the protection against counterfeiting of value documents, in particular bank notes, stocks, bonds, Certificates, vouchers, checks, high-quality entrance tickets, but also other papers that are prone to forgery, such as passports and other identification documents, as well as cards, such as credit or debit cards, as well as product securing elements, such as labels, seals, packaging and the like.
  • the structures with dimensions in the range of micrometers or nanometers are, for example, diffractive structures, micromirrors, matt structures or moth-eye structures.
  • the first printing unit, the first embossing, the second printing unit and the second embossing are arranged so that the embossed structures with dimensions in the range of microns or nanometers without turning the film web in the first lacquer layer and in the second lacquer layer are introduced.
  • the film web therefore does not have to be guided in a particularly advantageous manner by a turning device in which the film web is rotated in the conveying direction by 180 ° so that the previous front side and the previous rear side of the film web are interchanged.
  • the leadership of the film web is much quieter, so that the film web neither oscillations or stochastic movements in the plane of the film web still performs in the direction perpendicular to the surface of the film web or such Vibrations or stochastic movements can be largely avoided.
  • a device for surface treatment of the rear side of the film web to be arranged by means of corona discharge, atmospheric plasma or flame pretreatment in the direction of transport of the film web in front of the first printing unit.
  • a corresponding device for surface treatment of the front side of the film web can also be arranged in the conveying direction of the film web in front of the second printing unit. This surface treatment advantageously increases the adhesion and / or course of the front or rear side of the film web for a lacquer layer.
  • the thickness of the lacquer layer is preferably 0.5 ⁇ m to 20 ⁇ m, particularly preferably 2 ⁇ m to 15 ⁇ m and very particularly preferably 2 ⁇ m to 8 ⁇ m.
  • the 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 .mu.m to 36 .mu.m, for banknotes made of polymer or for composite film banknotes up to 100 .mu.m or for card bodies up to 200 ⁇ m.
  • PET polyethylene terephthalate
  • PEN polyethylene naphthalate
  • PP polypropylene
  • PC polycarbonate
  • a third printing unit for applying a wash ink on the second paint layer on the front side of the film web is arranged.
  • a printing and printing process is for example off WO 99/13157 A1 known.
  • a washing ink is applied, with an overlying Covering layer, which is applied to the washing ink in a subsequent process, can be removed again with a liquid by washing.
  • the cover layer consists, for example, of one or more metallic layers which are vapor-deposited onto the wash ink.
  • embossing devices of the prior art embossing cylinders are used with increasing diameter in the direction of movement of the film web to keep the mechanical tension of the film web within the entire printing and embossing device constant.
  • the diameter or the circumference of the embossing cylinder becomes larger with increasing distance from the Folienabrollung by 0.1 mm to 0.5 mm.
  • a correction of possible deviations between the individual processes takes place via a register control.
  • This means that a register deviation is corrected by a change in the rotational speed of the corresponding embossing cylinder.
  • this disadvantageously creates a difference between the speed of the surface of the embossing cylinder and the speed of the surface of the film web.
  • UV embossing however, the hardened structures on the film web or the lacquer layer are so strongly interlocked with the embossing cylinder that this type of correction of registration errors is not possible.
  • the first embossing machine has a first embossing cylinder, on the surface of which the first structures to be embossed are in the micrometer or nanometer range
  • the second embossing machine has a second embossing cylinder, on the surface of which the embossing is to be embossed second structures are in the micron or nanometer range, wherein the diameter of the first embossing cylinder and the diameter of the second embossing cylinder are the same size and the first and the second embossing cylinder have the same rotational speed.
  • the diameter or circumference of both embossing cylinders need not be exactly the same size.
  • the second embossing cylinder has a smaller by up to 2 mm circumference than the first embossing cylinder, so that the circumference of the embossing cylinder can be smaller than the embossing devices of the prior art with increasing distance from the Folienrollollung.
  • embossing shafts it can come not only by their manufacturing tolerances, but also by the use of sleeves, since their thickness is also included in the effective scope of the embossing cylinder.
  • the sleeves are also subject to significant variations in thickness, since their production is carried out by galvanic molding, which is known to be subject to greater manufacturing tolerances.
  • embossments on either side of the film web or multiple embossments on one side of the film web may be matched to each other, i. be applied to each other in the exact register.
  • the device is preferably divided into three areas.
  • the first area is the device for providing a film web and the first printing unit and the area up to the entrance to the first embossing unit.
  • the film is unwound and printed with a varnish layer, which is curable by means of ultraviolet radiation, so-called UV varnish, printed over the entire surface or in the form of a motif.
  • the mechanical tension of the film web is set such that the embossing of the first structures is introduced into the first lacquer layer of an elastically stretched film web.
  • the second area is formed by the first stamping mill and the area up to the entrance to the second printing unit. In this area, the mechanical tension of the film web is lowered compared to the first area. hereby The film web relaxes and contracts almost elastically again, which leads to a shortening of the arc length.
  • the third area is the second printing unit and the second stamping unit.
  • the mechanical tension of the film web is adjusted so that the arc length of the stretched film web corresponds exactly to the circumference of the second embossing cylinder.
  • a registration of the second lacquer layer with respect to the first lacquer layer can be carried out by means of register control, since the printing cylinder must have a certain slip due to the not yet cured lacquer layer.
  • the position and geometry of the film web between the embossing of the first structures and the embossing of the second structures can thus be determined or corrected, so that the embossing of the first structures and the embossing of the second structures in the exact Passer to each other.
  • the film web has a thickness of 12 microns and a width of 810 mm.
  • the embossing takes place with a mechanical tension of the film web of 200 N, wherein the first embossing cylinder has a circumference of 500 mm. The result is an arc length of 500 mm in the stretched state.
  • a reduction of the mechanical tension of the film web to 50 N resulting in an arc length of 498.5 mm.
  • an adaptation of the mechanical tension of the film web takes place such that the arc length corresponds exactly to the circumference of the second embossing cylinder. With a circumference of the second embossing cylinder of, for example, 499.5 mm, this results in a mechanical tension of the film web of about 150 N.
  • the embossing of the first structures to the embossing of the second structures is preferably carried out on the basis of register marks, which are automatically read out and lead to a correction of the mechanical tension of the film web.
  • register marks such as double wedge marks
  • optical register marks such as double wedge marks, can be used, which are additionally introduced into the embossing cylinder and are molded during the embossing process in the paint layer.
  • two double wedge marks are read out with a light barrier.
  • the time difference between the first double wedge mark and the second double wedge mark is determined from the signals of the light barrier. This time difference must be constant for all register marks, deviations lead to a control intervention, for example an adaptation of the mechanical tension of the film web.
