Definitions
- the present invention relates to a method for manufacturing a security paper, as well as a microlens thread for introduction into a paper web with such a method.
- value documents such as banknotes, stocks, bonds, certificates, vouchers, checks, valuable admission tickets and other papers that are at risk of counterfeiting, such as passports or other identification documents
- security elements can be developed, for example, in the form of a security thread that is completely or partially embedded in a banknote.
- microlens threads differ significantly from metalized threads and offer attractive optical properties.
- the microlens threads are furnished, on the side facing the viewer, with microlenses whose focusing effect is created by light refraction on an approximately spherically curved surface.
- micropatterns are located that are arranged such that, through the coaction of the microlenses and the micropatterns, it is possible to depict for the viewer a magnified image having special motion effects.
- the lens side of the thread is not provided with adhesive before the embedding in a paper web, as is the case in conventional security threads, such as hologram threads.
- conventional security threads such as hologram threads.
- the dispensation with adhesive on the top of the thread (lens side) often leads to a reduced stability of the banknotes produced, and in some cases even to a wrinkling on the banknote back.
- the object of the present invention is to avoid the disadvantages of the background art and especially to specify a method for manufacturing a security paper that facilitates a secure embedding of a microlens thread in the paper, and that simultaneously ensures, in the window regions in which the microlens thread emerges at the surface of the paper, an attractive visual appearance of the microlens thread.
- a registered introduction of the microlens thread can especially occur according to one of the methods described in document WO 2004/050991 A1. In this respect the disclosure of this document is incorporated in the present application by reference.
- the microlens thread can include a motif having a motif jump.
- an endless security element foil is first manufactured as roll material, wherein, when conventional manufacturing methods are used, breaking points always occur, especially gaps or a misalignment in the appearance of the security elements.
- breaking points come from the fact that the pre-products for the embossing dies used in manufacturing are generally manufactured as flat plates that are fitted on an impression or embossing cylinder.
- the image patterns that adjoin on both sides do not, as a general rule, match at the junctions and, after printing or embossing, lead, in the appearance of the finished security elements, to a motif jump of the kind cited.
- a microlens thread that includes a motif having a motif jump is introduced into the paper web in register, such that the motif jump comes to lie in one of the ridge regions of the paper web. The motif jump then remains hidden from the viewer.
- Motif jumps potentially also occur multiple times within an embossing cylinder.
- the patterns are composed from small segments by means of recombination
- seams having motif jumps result.
- motif jumps are created both in the grid of the micropatterns and in the grid of the microlenses. Here, it is usually attempted to bring the two seams into overlap at manufacture, such that the impression of only one motif jump is created for the viewer.
- the microlens thread is selectively printed on with an adhesive layer in those regions of its top that, at sheet formation, come to lie below ridge regions of the paper web.
- the microlens thread can include a motif having a motif jump, and the microlens thread be introduced in register, such that the motif jump comes to lie in one of the ridge regions of the paper web and is thus hidden for the viewer.
- the microlens thread immediately before entering into the paper web, is selectively provided with openings in those regions of its top that, at sheet formation, come to lie below ridge regions of the paper web.
- the openings are advantageously produced by punching or laser cutting. If the openings are produced only immediately before the entry of the microlens thread into the paper web, then they are preferably produced by laser cutting.
- the paper web is expediently formed having the predetermined ridge pattern in a paper machine, and the endless microlens thread enters into the paper machine.
- a microlens thread is provided whose top exhibits fractional regions having microlenses and microlens-free fractional regions, the microlens-free fractional regions being smaller than the width of the ridge regions of the ridge pattern in the paper web, and the microlens-free fractional regions being coated with adhesive before the introduction into the paper web.
- the microlens thread is especially introduced into the paper web not in register such that, in every window region, microlenses can be seen at least in some regions, and a portion of the adhesive-coated fractional regions always come to lie below ridge regions of the paper web.
- a microlens thread is provided that, on the one hand, exhibits fractional regions having microlenses, which fractional regions are coated with adhesive before the introduction into the paper web, and which are smaller than the width of the ridge regions of the ridge pattern in the paper web, and on the other hand, exhibits fractional regions having microlenses that are not coated with adhesive before the introduction into the paper web.
- the microlens thread is especially introduced into the paper web not in register, such that, in every window region, microlenses that exhibit no adhesive coating can be seen at least in some regions, and a portion of the adhesive-coated fractional regions always come to lie below ridge regions of the paper web.
- the microlens thread is advantageously contiguously provided on its bottom with an adhesive layer before the introduction into the paper web.
- the present invention also includes a microlens thread for introduction into a paper web, especially with the method just described.
- the microlens thread includes a top and an opposing bottom, the top exhibiting fractional regions having microlenses, and exhibiting microlens-free fractional regions that are coated with adhesive.
- fractional regions having microlenses and the microlens-free fractional regions advantageously form, on the top of the thread, alternating strips that each completely occupy the width of the microlens thread, and that each exhibit, in the longitudinal direction of the microlens thread, a dimension between 1 mm and 30 mm, preferably between 3 mm and 12 mm.
- fractional regions having microlenses and the microlens-free fractional regions can usually be present in the form of rectangles. However, it would also be possible for the fractional regions having microlenses and the microlens-free fractional regions to be present in the form of diagonals. Especially in wider threads, it is possible to produce diagonal paper ridges.
- the bottom of the microlens thread is preferably contiguously coated with adhesive.

- FIG. 1 shows a schematic diagram of a banknote 10 manufactured according to the present invention, having a microoptical window security thread 12 that, in the following, is also referred to as microlens thread for short.
- the microlens thread 12 emerges at the surface of the banknote 10 in window regions 14 , while it is embedded in the interior of the banknote 10 in the ridge regions 16 lying therebetween.
- the microlens thread 12 illustrated in FIGS. 2 and 4 is used for the manufacture of a security paper.
- FIG. 3 shows a cross-section of the security paper 50 with the already embedded microlens thread 12 .
- the microlens thread enters, for example in endless form, into a paper machine and is embedded there in a paper web forming on a cylinder mold.
- the paper web together with the embedded microlens thread is referred to in this description as security paper. From such a security paper is created, after further processing steps and separation of the ups of a paper web or a paper sheet, a banknote 10 as shown in FIG. 1 .
- FIG. 2 shows, schematically, the layer structure of the microlens thread 12 before the embedding in the security paper, with only those portions of the layer structure that are required to explain the functional principle being depicted.
- FIG. 4 shows a top view of the microlens thread 12 in FIG. 2 .
- the microlens thread 12 includes a support 20 in the form of a transparent plastic foil, for example a PET foil about 20 ⁇ m thick.
- the top 30 of the microlens thread 12 exhibits a grid-shaped arrangement of microlenses 22 that form, on the surface of the support foil, a lattice having a prechosen symmetry.
- the spherically or aspherically designed microlenses 22 preferably exhibit a diameter between 5 ⁇ m and 50 ⁇ m, and especially a diameter between merely 10 ⁇ m and 35 ⁇ m, and are thus not perceptible with the naked eye. It is understood that, in other designs, also larger or smaller dimensions may be considered. Also the use of cylindrical lenses is similarly possible.
- a motif layer 26 that includes a likewise grid-shaped arrangement of micromotif elements 28 .
- the arrangement of the micromotif elements 28 forms a lattice having a prechosen symmetry, with a desired magnification effect, characteristic motion effects and/or tilt effects being produced due to the coordination of the lattice of the microlenses 22 and the arrangement of the micromotif elements 28 .
- the micromotif elements are not perceptible with the naked eye.
- WO 2009/000528 A1 in which it is explained that the micropatterns can also consist of image fragments that are not arranged repeatingly.
- the microlens thread 12 typically includes further layers 24 , such as protective, cover or further functional layers, which, however, are not significant for the present invention and are thus not described in greater detail.
- a paper web 50 having a predetermined ridge pattern 18 ( FIG. 1 ) is produced on the cylinder mold of a paper machine.
- the ridge pattern 18 exhibits ridge regions 16 in which the microlens thread 12 is later embedded in the interior of the finished paper web 50 . Between the ridge regions 16 lie window regions 14 in which the microlens thread 12 emerges at the surface of the finished paper web 50 .
- the microlens thread 12 is provided on its top 30 with an adhesive layer 40 in the form of the ridge pattern 18 , such that the adhesive layer 40 forms an adhesive pattern 48 whose sequence of uncoated regions 44 and coated regions 46 corresponds to the sequence of the window regions 14 and ridge regions 16 of the ridge pattern 18 .
- the bottom 32 of the microlens thread 12 is provided with a contiguous adhesive layer 42 .
- Said microlens thread 12 coated in this way with adhesive 40 , 42 is now introduced in register into the paper web 50 , such that the adhesive-coated regions 46 of the microlens thread coincide with the ridge regions 16 of the paper web 50 , as shown in FIG. 3 .
- the microlens thread 12 can be introduced into the paper web by means of a biased coil.
- a first sensor detects the position of the coated regions 46 shortly before the introduction into the paper web, a second sensor the position of the ridges 16 formed in the paper web immediately after sheet formation.
- the positions detected by the two sensors are analyzed and used to control the magnitude of the bias.
- the bias is increased, the microlens thread 12 is stretched more strongly, and when the bias is lowered, the stretching is reduced. In this way, the microlens thread 12 , with its coated and uncoated regions 44 , 46 , can be aligned in perfect register with the window and ridge regions 14 , 16 .
- the procedure is preferably such that the thread bears a register mark that is recognized particularly well by a detection system.
- the thread embedding is then controlled at the thread by means of tensile stress in such a way that the register mark of the thread has a fixed local reference to the register mark of the paper, usually a watermark.
- the regions in which the thread exhibits adhesive on the top then have a fixed, known local reference to the register mark of the thread.
- the ridge regions in the paper have a fixed local relationship to the register mark in the paper.
- the ridge regions 16 of the paper web 50 are glued to the microlens thread 12 , such that a secure embedding of the microlens thread 12 , without wrinkling and without lifting up or tearing out the paper ridges at manufacture, is ensured.
- stability of the paper ridges to circulation stresses is significantly improved.
- the microlenses 22 of the uncoated regions 44 that are visible in the window regions 14 remain free of adhesive, such that the optical properties of the microlenses 22 are not impaired.
- the microlens thread 12 thus displays, after its embedding in the paper web 50 , the desired clear visual appearance in the window regions 14 .
- the uncoated regions 44 and the coated regions 46 exhibit the same size as the window regions 14 and the ridge regions 16 , respectively. In some embodiments, it is also provided that the coated regions 46 are smaller, for example no more than 10% or no more than 50% smaller, than the ridge regions 16 . How much shorter the glue-coated portion should be compared with the paper ridges of the thread also depends strongly on the register tolerance when embedding the thread in register. With, for example, ⁇ 1 mm register tolerance when introducing the thread in register, the glue-free regions of the thread should be 2 mm shorter than the paper ridges. Even if, in each case, only a portion of the microlens thread 12 is glued to the ridge regions 16 , a significantly improved embedding results compared with the background art.
- the uncoated regions 44 are somewhat smaller than the window regions 14 may be considered. However, the focusing effect of adhesive-coated microlenses 22 in the window regions 14 is reduced or canceled, such that the uncoated regions 44 are preferably not more than 10%, particularly preferably not more than 5% smaller than the window regions 14 .
- a further advantage of the introduction of the microlens thread 12 in register consists in that any motif jumps 34 in the motif image can be hidden under a paper ridge 16 of the security paper 50 , as shown in FIG. 3 . In this way, the uniformity of the visual appearance of the microlens thread 12 is further increased.
- the microlens thread 12 is not introduced into the paper web 50 in register, but rather is, immediately before the entry into the paper machine, printed on with an adhesive pattern 48 in such a way that the coated regions 46 come to lie in the depressed sections of the cylinder mold, in which the paper ridges 16 form.
- a sensor for example, can detect the position of the ridges 16 formed in the paper web at sheet formation, and the detected position can be used to control the printing positions for the adhesive pattern 48 .
- the uncoated and coated regions 44 , 46 can be aligned in perfect register with the window and ridge regions 14 , 16 .
- FIGS. 5 and 6 show a top view and a cross-section, respectively, of the microlens thread 60 before the embedding in the security paper
- FIG. 7 shows a cross-section of the security paper 50 having the embedded microlens thread 60 .
- the microlens thread 60 is not coated on its top 30 with adhesive, but rather, before the introduction into the paper web 50 , it is provided with an opening pattern 68 in the form of the ridge pattern 18 .
- the opening pattern 68 consists of a sequence of regions 66 , having openings 62 and regions 64 without openings, that corresponds to the sequence of the ridge regions 16 and window regions 14 of the ridge pattern 18 .
- the bottom 32 of the microlens thread 60 is preferably provided with a contiguous adhesive layer 42 .
- the microlens thread 60 is now introduced into the paper web 50 in register, such that the regions 66 of the microlens thread 60 that are provided with openings coincide with the ridge regions 16 of the paper web 50 , as already described in principle in connection with FIGS. 2 to 4 .
- the first sensor detects the position of the openings 62 shortly before the introduction of the microlens thread 12 into the paper web. In this way, the microlens thread 60 with its opening pattern 68 can be aligned in perfect register with the window and ridge regions 14 , 16 .
- the openings 62 can, for example, be punched or produced through laser cutting. Every region 66 can include one or also multiple openings 62 .
- FIGS. 6 and 7 show a design having, in each case, only one opening 62 per region 66
- FIG. 5 illustrates a design having three openings 62 per region 66 .
- the microlens thread 60 is not introduced into the paper web 50 in register, but rather, it is provided only immediately before the entry into the paper machine, through laser impingement, with the opening pattern 68 , in such a way that the regions 66 having openings 62 come to lie in the depressed sections of the cylinder mold, in which the paper ridges 16 form.
- a sensor can detect the position of the ridges 16 formed in the paper web, and the detected position can be used to control the laser beam.
- the opening pattern 68 can be aligned in perfect register with the window and ridge regions 14 , 16 .
- a microlens thread 70 is used that exhibits, on its top 30 , a sequence of fractional regions 74 having microlenses 22 and microlens-free fractional regions 76 .
- the motif layer and any further layers of the microlens thread 70 are, for the sake of clarity, not shown in FIGS. 8 and 9 .
- the microlens-free fractional regions 76 of the top 30 are coated with adhesive 40 , and also the bottom of the microlens thread 70 is contiguously coated with adhesive 42 .
- the adhesive-coated, microlens-free fractional regions 76 are developed to be smaller than the width of the window regions 14 of the ridge pattern 18 . In this way, it is ensured that, when the microlens thread 70 is not introduced into a security paper 50 in register, microlenses 22 can be seen in every window region 14 , at least in some regions ( FIG. 9 ).
- the adhesive-coated regions can definitely also exhibit microlenses. Indeed, said microlenses would become optically ineffective due to the adhesive coating, but they permit a uniform design of the thread with microlenses.
- the adhesive or glue used in the present invention can be, for example, a heat seal coating. Furthermore, the adhesive can exhibit security features, for example dyes or color pigments and luminescent substances.
