Description
The invention relates to a method for producing a multi-element strip which is intended to be applied to a target substrate, to a multi-element strip and to a corresponding use for application to a target substrate.
Data carriers, such as value documents or certificates, and other value articles, such as name-plate goods, are usually provided with security elements which enable the authenticity of the data carrier to be checked and at the same time serve as protection against unauthorized copying. The security element can be integrated in the substrate of the data carrier or applied to the substrate of the data carrier, for example.
Different methods are known for the positionally accurate application of individual security elements to individual data carriers.
On a layout piece (Mehrfachnutzen), for example a large banknote layout (banknotenbergen) comprising a plurality of individual units (or so-called layout pieces), a multi-unit strip (mehrnutzentreifen) can be applied, on which a plurality of security elements are arranged one behind the other. The position of the multi-element strip relative to the tile is not important in many applications. However, locally accurate application is also desired in some cases.
EP 2848425 a2 proposes the production of a plurality of security elements on a continuous web as an intermediate carrier, one behind the other and at a distance from one another. The security elements are accurately manufactured in the form in which they should be applied to the target substrate.
In an alternative solution, a manufactured area is provided with the outer shape of the security element before and/or while being applied to the target substrate.
The object of the present invention is to provide a flexible method which ensures good positioning, in particular.
This object is achieved according to the invention by the features of the independent claims. Further developments of the invention are the subject matter of the dependent claims.
The method for manufacturing a multi-element strip of the present invention has at least the following steps. The multi-unit segments are fabricated on an intermediate carrier, wherein the multi-unit segments are configured for application on a multi-unit area of a target substrate. Two outer segments are produced on the intermediate carrier for each multi-unit segment, which outer segments are provided for application on an outer region of the target substrate. The two outer segments of the multi-unit segment together with the multi-unit segment form a multi-unit strip. For applying the multi-unit strip on the target substrate, the outer segments of the multi-unit strip are pre-structured (vorstrukturrien) on an intermediate carrier. The intermediate carrier is an intermediate carrier web on which a plurality of multi-element strips are produced side by side. The intermediate carrier web is cut into a plurality of strip section webs, on which a plurality of pre-structured multi-element strips are arranged in each case one after the other along the length.
The multi-unit strip may then be transported to a target substrate by conventional equipment. Positional inaccuracies that may exist in the pre-structuring do not adversely affect the positioning of the multi-unit segments.
Furthermore, the influence of the pre-structuring on the multi-unit segment is avoided by the pre-structuring in the outer segment. Mechanical pre-structuring may, for example, lead to deformations, optical pre-structuring by means of a laser may, for example, lead to premature thermal activation of the adhesive paste, and chemical pre-structuring may, for example, be introduced into the multi-element segment as a result of diffusion effects.
The pre-structuring before the cutting of the intermediate carrier web into strip section webs has a number of advantages, which will be explained in more detail below.
The structuring is preferably carried out in the longitudinal direction for the multi-element strips lying next to one another on the intermediate carrier web, offset to one another. The possible, in particular mechanical, intermediate carrier web loads caused by the pre-structuring can be spatially distributed (and thus locally reduced) by the pre-structured offset.
The outer segment preferably includes a minimum segment that is applied to the target substrate and a pre-structured segment. For two (adjacent or) mutually subsequent multi-element strips, an intermediate region may be present between two outer segments, in particular between two pre-structured segments.
The pre-structured offset can be implemented independently of the position of the multi-unit segment on the intermediate carrier web. For example, the side-by-side multi-unit segments can be located (identically) on the intermediate carrier web without being offset from one another. The location of the pre-structuring may vary within the pre-structured segment (and/or the intermediate region). Alternatively or additionally, the length of the smallest segment may be varied in order to obtain the amount of pre-structured displacement.
It is particularly preferred that at least the side-by-side multi-element strips are produced offset to one another in the longitudinal direction. The offset of the multi-element strip on the intermediate carrier web can be advantageous for a pre-structured offset, i.e. for generating or increasing a pre-structured offset.
If the side-by-side multi-element strips are pre-structured with a misalignment, the amount of pre-structuring misalignment is preferably greater than 4 mm.
The process of applying the multi-element tape on the target substrate is performed with positional tolerances. The position tolerance depends on the equipment used and is generally between 0.5 and 1mm, however in any case below 2 mm. Here, the position tolerance represents the maximum deviation of the actual position of the multi-cell strip on the target substrate from the reference position, i.e., the position of the multi-cell area.
The amount of pre-structured misalignment is preferably greater than twice the positional tolerance. The minimum segment is particularly preferably greater than twice the positional tolerance.
The pre-structuring tolerance can be greater than the positional tolerance. With the solution of the invention, the size of the pre-structured tolerance does not affect the positioning tolerance. In other words, the processing can be carried out more cost-effectively and with less control effort during the pre-structuring.
In a preferred embodiment, the intermediate carrier web comprises a primary carrier and a secondary carrier. The secondary carrier is usually glued to the primary carrier. This embodiment has the advantage that only the secondary support can be changed during the pre-structuring step. The primary carrier is not included in the pre-structuring. The adhesive layer preferably has a thickness of 2 to 3 μm.
In one embodiment, the primary carrier is glued to the secondary carrier (on the rear side) before the step of pre-structuring the multi-element strip. In particular, if the pre-structuring is carried out by means of laser irradiation, it can be considered to protect the primary support by means of a laser-impermeable barrier layer, for example a copper layer, which is arranged between the primary support and the secondary support.
In a particularly preferred embodiment, the primary carrier is applied to the secondary carrier (on the rear side) only after the step of pre-structuring the multi-element strip. This design increases the flexibility in the pre-structuring and ensures the required stability. Depending on the requirements, different main carriers can be applied and/or can be structured differently. The primary carrier web is applied to the rear side of the secondary carrier web, said application taking place before the intermediate carrier is cut. The later application, optionally in combination with the offset, in particular achieves a pre-structuring that cuts, removes or cuts the main carrier (and the multi-element strip) over the entire width of the strip section web.
In the step of pre-structuring, the produced outer segment is pre-structured, in particular mechanically, chemically or by irradiation. The pre-structuring corresponds to a local or local change of the produced outer segments. The pre-structuring usually extends over the entire width of the web of strip sections (or over the length of the pre-structured segments). The pre-structuring can be used in particular to avoid dirt, for example, as a result of chipping of the multi-unit segments, as is known precisely for multi-unit segments with an embossed lacquer layer. However, the pre-structuring may also be beneficial to assist in reliably applying on the target substrate, especially if otherwise adhesion problems may occur when the intermediate carrier is detached from the multi-unit segment. Laser radiation, UV radiation and/or (ultra) sound wave based methods are particularly suitable as the radiation-type pre-structuring. The mechanical pre-structuring may comprise punching, blanking, stamping or pressing. The pre-structuring of the chemical formula may include local removal (corrosion) or local modification (for example local softening of a brittle imprint lacquer). The pre-structuring can be designed as a separate pre-structuring, as a pre-structuring that repeats in partial regions, or as a uniform or repeating pre-structuring throughout the entire pre-structured segment. The pre-structuring can likewise extend over part or all of the area of the pre-structured segments, in particular by a continuous pre-structuring in a pattern or in a meandering manner over part or all of the area.
Particularly preferably, the outer segments of two adjacent multi-unit segments are jointly pre-structured. The two outer segments may in particular comprise a common pre-structured segment. Alternatively, there are two spaced-apart pre-structured segments and optionally an intermediate region, wherein the pre-structured segments (and the intermediate region) are collectively and uniformly pre-structured.
Advantageously, in the step of producing the outer sections, a positioning aid for positioning the multi-unit section relative to the target substrate and/or a production identifier are produced in at least one of the outer sections, which production identifier unambiguously identifies the multi-unit strip, the strip portion web and/or the intermediate carrier web. If the positioning aid is produced jointly with the multi-unit segment, and not independently thereof, as in the case of a pre-structuring, no additional tolerances occur. The production identifier represents the multi-element strip, the strip section web and/or the intermediate carrier web in a one-to-one correspondence at least in the production system. It is thus possible to detect and store which components have been processed or which components are at least partially contained in which end product, such as a banknote.
The multi-cell segment that is manufactured is a multi-layer structure that includes at least three sub-layers. The multilayer structure comprises in particular at least three of the following sublayers: a first embossing lacquer layer, a second embossing lacquer layer, a reflector layer, a protective layer, a release layer and/or an adhesion layer.
The multi-unit strip produced according to the method of the present invention is for application to a target substrate such that the multi-unit segments are on a multi-unit area of the target substrate and the outer segments are on an outer area of the target substrate. In particular, a plurality of multi-element strips having outer segments of optionally different lengths can be applied to the target substrate. In a next step, the intermediate carrier is detached from the applied multi-unit strip. Individual cells can be created by cutting the multi-cell area of the target substrate with the applied multi-cell tape.
Further embodiments and advantages of the invention are explained below with reference to the drawings, which are not drawn to scale and are shown in the figures to improve the intuitiveness.

In fig. 1, a target substrate 10 is shown on which a multi-element tape 20 has been applied. Starting with the example of a banknote as a product, the target substrate 10 is a large version of a banknote substrate and the multi-unit strip 20 is a security strip for multiple banknotes.
The target substrate 10 includes a multi-cell region 12 and an outer region 16. The multi-cell region 12 is defined as being comprised of a plurality of individual cells 14. The length of the multiple unit region, L12, corresponds to a multiple of the length of the individual units, L14. Shown is a multi-cell region having four by four individual cells. Outer region 16 surrounds multicell region 12. After which a banknote is formed, for example, from each individual unit.
Four multi-element strips 20 are applied on the target substrate 10. Each multi-cell strip 20 is on a multi-cell region 12 having four individual cells 14 and on an outer region 16. The length of the multiple-unit band, L20, is intentionally greater than the length of the multiple-unit region, L12.
The individual segments and corresponding lengths of the multi-unit strip are shown in detail in fig. 2.
Fig. 2 shows two multi-element strips 20 and 20A in a top view, which are still arranged on an intermediate carrier, which is not shown in the drawing because it is located underneath. The multi-unit strip 20, 20A comprises multi-unit segments 21, 21A and outer segments 22, 22A on each side. The multi-unit segment 21 is between its two outer segments, but only one of them is shown in fig. 2, respectively, i.e. the outer segment 22 on the right side of the multi-unit strip 20 and the outer segment 22A on the left side of the multi-unit segment 20A are shown. The length L21 of the multi-unit segment 21 corresponds to the length of the multi-unit region of the target substrate to which it should be applied (L21 ═ L12).
The two outer segments, together with the multi-unit segment, are also applied, at least in part, to the target substrate, i.e., to an outer region of the target substrate. Thus, the length of the applied multi-unit strip consists of the length of the multi-unit segment and the length of the two outer segments. If, for example, the two outer segments are of the same length, then this applies: l20 ═ L21+2 × L22. If the two (right and left) outer segments differ in length, then this applies: l20 ═ L21+ L22_ left + L22_ right.
An intermediate region 23, which is not provided for (not applied to) the target substrate, can optionally be provided between the two outer segments 22 and 22A of the two multi-element strips 20 and 20A following one another.
On the intermediate support, the pre-structuring can be carried out by different means and different effects. The pre-structuring provides for applying the multi-element tape to a target substrate.
As can be seen in fig. 2, the pre-structuring 24 may define the outer segment 22. By means of the pre-structuring with a defined action, the outer segment 22 is formed on the intermediate carrier, which should be applied to the target substrate with its preset length L22.
The outer segments on the intermediate carrier may be divided into the smallest outer segment 26 and the pre-structured segment 27 that should be applied to the target substrate with their length L26. The pre-structuring 24 can then be arranged in the pre-structuring segment 27 at any desired position. The length L22 of the outer segment is in the range: l26< L22< L26+ L27.
If the pre-structuring 24 is a defined (length) pre-structuring, the position of the pre-structuring 24 in the pre-structuring segment 27 determines the length L22 of the outer segment to be applied. For example, the pre-structuring 24 may be realized by subtractive laser irradiation of a multilayer structure formed on an intermediate carrier. In other examples, the pre-structuring is achieved mechanically, chemically or by other (non-laser) irradiation, in particular by modification and/or removal. The multilayer structure may be only partially pre-structured at the edges of the outer segments 22, in this embodiment: removed or pre-structured (e.g., removed) in the entire region that terminates at the edge of the outer segment 22.
However, the pre-structuring 24 on the intermediate support can also be designed as a variable (length) pre-structuring. By variable pre-structuring in the pre-structured segments 27, a multi-unit strip 20 having outer segments 22 whose length L22 is determined at the time of application can be applied to a target substrate. Variable pre-structuring 24 extends over pre-structured segment 27 (having length L27).
Variably pre-structured multi-unit strips 20 are present on the intermediate carrier as the smallest multi-unit strip 25 having a minimum length L25(L25 ═ L21+ L26). The actual length of the applied multi-unit band or outer segment 22 is determined when the multi-unit band 20 is applied to the target substrate. By variable pre-structuring, the smallest outer segment 26 is always applied and the pre-structured segment 27 is applied in variable length, i.e. in particular only partially.
The variable pre-structuring can be achieved, for example, mechanically, by overall perforation, overall and, if appropriate, randomly distributed punch structures or other mechanical processes extending over the segments or overall. Likewise, it is also possible to remove or change the segments by irradiating, for example, a perforated surface or a pattern-like, if appropriate randomly distributed, segment. It is likewise conceivable to treat the pre-structured regions chemically, overall or in a distributed manner, so that, for example, the embossing lacquer does not harden or soften again (by UV light).
In a special embodiment, a uniform pre-structuring 24 from the outer segments 22 of the multi-unit band 20 up to the outer segments 22A of the multi-unit band 20A is sufficient. The uniform pre-structuring may be a predetermined pre-structuring or a variable pre-structuring.
In fig. 2, two adjacent pre-structured regions 27, 27A together with the optionally present intermediate segment 23 are referred to as a preparation segment 28. The preparation segment 28 has a length L28, wherein 2 × L27< L28<2 × L27+ L23. Thus, a minimum (not pre-structured) multi-unit strip 25 and a preparation segment 28 comprising a pre-structure are arranged alternately on the intermediate carrier. This division is used in the following figures, which mainly observe the local distribution of the pre-structuring on the intermediate carrier macro-plate.
In the ideal case, half of the pre-structured segments 27 are applied together on the target substrate, as is illustrated in fig. 2 by the central position of the pre-structure 24 in the pre-structured segments 27. However, due to position tolerances when applied, the length of the applied outer segment L22 may be between the minimum length L26 and the sum of the minimum length L26 and the pre-structured length L27 (L26< L22< L26+ L27).
The positional tolerance as applied relates to the position of the multi-unit segment 21 relative to the position of the multi-unit area. The positional tolerance depends on the equipment used but is typically between 0.5 and 1.5 mm. The position of the formed multi-unit segment 21 and the positional tolerance upon application are in the present solution independent of the pre-structuring. Therefore, inaccuracies or tolerances in the pre-structuring (pre-structuring tolerances) do not affect the positional tolerances of the multi-unit segments when applied. The position of the pre-structuring 24 can be varied randomly in the sense of pre-structuring tolerances or intentionally as explained in accordance with the following figures.
In fig. 3, an intermediate carrier web 30 is shown which comprises a plurality of strip section webs 32. The intermediate carrier web 30 preferably comprises at least four strip section webs 32. The shown intermediate carrier web 30 also comprises optional control part webs 31, 33 and 35. On the strip portion web 32, the smallest multi-element strip 25 is arranged and the preparation segment 28, which comprises a pre-structuring, is arranged. The preparation section 28 preferably comprises, for example, two pre-structuring and intermediate sections or a continuous pre-structuring. The strip portion web can be designed as described in fig. 2.
The strip part webs 32A, 32B and 32C lie side by side on the intermediate carrier web 30. From left to right on the strip portion web 32A, a first preparation segment 28, a smallest multi-unit strip 25A, a second preparation segment 28 and an adjacent smallest multi-unit strip 25B can be identified.
As shown in the multi-unit strip 25A, the multi-unit segment includes a graphic (star, cross, star) that is repeated three times (corresponding to the number of individual units shown). The pattern is a security element and may be provided, for example, as a hologram, as an optically variable element and/or as a relief structure based on a coating. The outer segment without the graphic is only shown in the figure by the distance of the first star of the graphic from the preparation segment 28. The other strip portion webs 32, 32B, 32C likewise comprise a plurality of successive multi-element strips which are arranged between the preparation sections. The graphics are not repeatedly displayed in order for the other illustrated aspects to be recognizable.
Starting from the intermediate carrier web 30, the multi-unit segments and the outer segments of the multi-unit strip are formed on the intermediate carrier. The smallest multi-unit strips 25A, 25B comprise one multi-unit segment and two outer segments, respectively. The smallest multiple unit strip 25 is completely disposed for application on the target substrate by its length. The multi-unit segments should then be applied over the multi-unit area of the target substrate as described in fig. 1 and the external segments should be applied over the external area of the target substrate. In the preparation area 28, the two outer sections of the multi-unit strip are pre-structured on an intermediate carrier web 30. A plurality of formed multi-element strips (on the strip portion web 32) are arranged next to one another on the intermediate carrier web 30. The strip portion webs are produced from the intermediate carrier web 30 as described in connection with fig. 2, by cutting the intermediate carrier web 30 into a plurality of strip portion webs 32, on which a plurality of pre-structured multi-element strips are respectively arranged one behind the other along the length.
Fig. 3 shows a staggered arrangement of the multi-element strips 25A, 25B in the strip portion webs 32A, 32B, 32C on the intermediate carrier web 30. By displacing the multi-element strips, the pre-structured segments 28 are also displaced from one another on the intermediate carrier web 30. The offset is selected such that at least the pre-structured sections of the strip section webs that are adjacent to one another are arranged without overlapping.
The pre-structured misalignment spreads out the loads, in particular of the intermediate carriers, which may occur as a result of the pre-structuring. The dispersion of the load may also improve the positional accuracy when applied. Furthermore, the offset allows additional forms of pre-structuring, such as blanking of the entire preparation segment. The offset does not affect the cut strip portion web 32 or its application because they are identical in the sequence of multi-element strips.
The pre-structuring 28 is for example evenly distributed over the length of the multi-element strip. The misalignment of the multi-element strips may in particular be more than half the length of an individual element (and less than twice the length of an individual element).
Preparation aid marks 311, 312 can be provided on the intermediate carrier web 30, in particular on the control part webs 31, 33 and 35; 331. 332, 334, 335 and 351, 352. The preparation aid marks are used at least in the step of pre-structuring to determine the position where the pre-structuring is required (and/or its length and/or its offset). However, the preparation of the auxiliary mark may also be used for the step of (offset) manufacturing the multi-element strip. Preparation assist mark 311 illustrates the position of preparation segment 28 between multi-unit strips 25A and 25B. The second auxiliary mark 312 may be provided for determining the width of the preparation segment 28 and/or the position of the second pre-structuring. The control portion web 33 also contains corresponding preparation aid marks 331, 332. The amount of misalignment of the multi-element strip can be determined by means of at least one other preparation aid mark 333, 353. The preparation aid markings 333, 334 or 353, 354 here likewise mark the position of the pre-structuring on the adjacent strip portion web 32.
In the variant shown in fig. 3, the multiple-element strips of the plurality of strip section webs are arranged offset to one another. The strip section webs or the multiple-element strips of at least three strip section webs can be arranged (or produced) offset to one another.
Fig. 4 shows an otherwise similar example, shown in a simplified form, in which the multi-element strips of only the strip portions 32A, 32B and 32B, 32C, respectively, which are arranged next to one another are offset from one another. While the multi-element strips of the strip section webs 32A and 32C are arranged without displacement.
In a variant not shown separately, the amount of misalignment of the multi-unit strip may be less than the length L28 of the preparation segment 28. The preparation segments of adjacent strip sections on the intermediate carrier are then arranged offset to one another, but overlapping (and not without overlap as in fig. 3 and 4).
Fig. 5 shows a variant solution of a pre-structuring with a misalignment, but the multi-unit segment is manufactured without a misalignment.
The multi-unit segments 21A, 21B of the strip section webs 32A, 32B and 32C are produced without offset on the intermediate carrier web. Only the pre-structuring of the multi-element strips on the intermediate carrier web 30 is realized in a staggered manner. The preparation regions 28 (and thus the pre-structuring) of adjacent strip section webs 32A, 32B are arranged offset to one another. Due to the pre-structured misalignment, the length of the smallest (and actually applied) outer segments 26A, 26B on the intermediate carrier web 30 changes. For multiple-element strips on the side-by-side strip portion webs 32A, 32B and/or for multiple-element strips of the portion web 32B that follow one another, there are outer segments of different lengths.
If, for example, the pre-structuring forms the boundary of the preparation region, the pre-structuring of the side-by-side strip section webs is also arranged in the exemplary embodiment shown without overlapping. Whereas for a wider or even uniform pre-structuring in the preparation area 28, the pre-structuring of the side-by-side partial web of strips overlaps. The amount of the pre-structuring offset and the width of the pre-structuring segments are preferably selected such that the pre-structuring of the side-by-side strip section webs does not overlap.
As shown in fig. 5, the pre-structured shift can be provided without the multi-element band shift, or alternatively the pre-structured shift and the multi-element band shift can also be provided together in accordance with fig. 3 or fig. 4.
As a further alternative, an additional intermediate web 39 can be arranged between the strip section webs 32A, 32B, as shown in fig. 5. The intermediate web 39 can be stabilized in a manner similar to the pre-structured offset. Like the control web 31, the intermediate web 39 is not necessary and is removed accordingly after the intermediate carrier web 30 has been cut into the strip portion webs 32.
Fig. 6 shows a cross section through an individual unit 14, for example a banknote, having a security element in the form of an individual unit strip 620 which is applied to a (target) substrate. The individual cells 620 of the multi-cell ribbon 20 comprise a multi-layer structure. The individual element strips 620 are fixed to the target substrate by means of an adhesive layer 628 and comprise, for example, a metal layer 626, an embossing layer 624 (with a surface relief structure not shown, on which the metal layer 626 is present) and an optional protective lacquer layer 622. As shown for the individual unit strips 620, they may be on a substrate coating 612 of the substrate, for example a continuous or structured printing layer or a continuous lacquer layer. Alternatively, as described for the other individual unit strips 620B, the individual unit strips may be applied directly on the substrate body 610, in particular in the recesses of the substrate coating 618.
The substrate includes a substrate body 610, which is typically composed of paper, plastic, or a hybrid composite (paper and plastic layers). The security element 616 may be embedded in the substrate body 610. The individual unit strips 620 and 620B may be arranged at least partially overlapping or completely overlapping. They may complement each other as a security element or be visually complementary to the embedded security element 616, particularly to the viewer.
A plurality of multi-element strips may be applied (particularly simultaneously) on the target substrate as shown in figure 1. As can be seen by way of example in the case of two separate unit strips 620 and 620B applied to the front and back sides of the substrates 610, 612, 618, a multi-unit strip (different depending on the front or back side or the same depending on the front or back side, respectively) can be applied to the target substrate on the front and back sides in fig. 1. The multi-element strips applied to the front and rear side can be arranged completely overlapping (superposed), partially overlapping (parallel to one another or intersecting in each individual element) or non-overlapping (non-superposed and preferably parallel to one another) on the target substrate.
Fig. 7 and 8 show two examples of cross sections through a two-layer intermediate support with a pre-structured multi-element strip produced thereon.
According to the embodiment in fig. 7, a plurality of unit strips 25 are produced one behind the other on a primary intermediate carrier 733. The multi-cell stripe 25 is implemented by the multilayer structures 721 to 727. In this case, a (unpatterned) multilayer structure is also partially produced in the preparation region 28.
The main intermediate carriers 733 are also present as intermediate carrier webs and can therefore be simply punched out to the size of the (pre-structured segments or) preparation segments 28. After the pre-structuring, a secondary carrier 731 is applied to the rear side of the primary carrier 733 by means of an adhesive layer 732. The holes formed in the intermediate carrier web as a result of the blanking (or the carrier gaps in the web of the strip portions) are thus closed again. Positioning aids 712, which aid positioning when applying the multi-unit segment, may optionally be manufactured in the preparation segment 28. The double-layer intermediate carrier web now having the pre-structured multi-element strips 25 is cut into strip-part webs.
The illustrated multilayer structure 721 to 727 of the multi-cell strip comprises a release layer 721, a lacquer layer 722, a reflector layer 723, a dielectric layer 724, an absorber layer 725, only an optional intermediate film 726 and an adhesion layer 727. The adhesive layer 727 serves to fix the further layers 722 to 726 to the target substrate and can be provided, in particular, as a hot-press adhesive lacquer. The release layer 721 facilitates the release of the multi-unit strips from the intermediate carrier when applied to a target substrate. The lacquer layer 722 may be provided as an embossed lacquer layer having an embossed relief structure. Embossed may be relief for holograms, micro mirrors, micro lenses or sub-lambda structures. The reflector layer 723 may act as a reflector on the relief of the lacquer layer 722 and/or form together with the dielectric layer 724 (of constant or locally varying thickness) and the absorber layer 725 a visually variable thin layer element.
Fig. 8 shows another design of a multi-element strip and a pre-structuring.
The intermediate carrier is designed as a double layer with a primary carrier 833 and a secondary carrier 831 affixed by means of an adhesive layer 832. A multi-unit strip 25 comprising multi-unit segments 26 and outer segments 21 is manufactured on the intermediate carrier.
The multi-layer structure 821-826 of the multi-cell strip comprises in the multi-cell segment 21 an optional release layer 821, a (first radiation hardened) lacquer layer 822, a (second radiation hardened) imprint lacquer layer 823, a reflector layer 824 (e.g. a metal layer), an optional main layer 825 (adhesion promoter) and an adhesion layer 826. The functions of the layers already discussed are not re-set here. The second lacquer layer 822 under the non-embossed side of the embossing lacquer layer 823 has proved advantageous for an embossed relief structure. The reflector layer 824 together with the relief structure of the embossing lacquer layer forms a multi-unit segment pattern or security element.
No metal layer is arranged in the smallest outer section 26 of the multi-unit strip 25. The outer segment is non-graphic. The embossing lacquer layer 823 is therefore normally unembossed in the smallest outer sections, i.e. without a relief structure. The layers 821, 822, 824, 825, and 826 that are not patterned exist in the outer sections as in the multi-cell section.
The embossing lacquer layer 823 (and the layers 821 and 822 lying thereunder) extends into the preparation area. In the preparation area, at least the embossing lacquer layer 823 is pre-structured on both sides. The two pre-structures 88 extend into the primary support 833. It is conceivable, but not necessary in the present embodiment, to arrange a plurality of substructures side by side or to provide a plurality of substructures for the segments 28. Without the secondary carrier 831, the web of the strip section with the multi-element strip may crack (positioning problems) or in extreme cases even break. The pre-structuring 88 can be produced, for example, by perforating or cutting to a corresponding depth, in particular by means of a laser or mechanically.
The position of the positioning aids 82, 86 and the production identifier 84 relative to the other layers can be seen in fig. 8. The corresponding functions of the positioning aid and the production identifier are now described with reference to fig. 9.
Fig. 9 shows, in a plan view, a strip portion web with a plurality of multi-element strips 20, similarly to fig. 2. Only the additional elements are described.
Positioning aids 86 may be fabricated in the outer segments 22 that account for the exact location of the multi-unit segments. Positioning aid 86 for the multi-unit segment is manufactured together in the step of manufacturing the outer segment, as is optional positioning aid 82 for pre-structured segment 27. The location of the pre-structuring can be determined for the pre-structuring step by means of the positioning aid 82. The (possibly different) length of the outer segment 22 and the width of the intermediate segment 23 can thus be flexibly produced or taken into account.
