Definitions

  • the invention relates to a method for producing a security element, wherein a substrate is provided which has a front and a back, at least for certain radiation is translucent and has a watermark, which modulates the opacity of the substrate and which has a certain range on the front side a printing element is applied, which covers the particular area of the watermark and is modifiable by the particular radiation, and the substrate is irradiated from the back with the particular radiation, wherein the particular area of the watermark is used with respect to the modification of the printing element as a mask and the printing element in the register is modified to the watermark.
  • watermarks are known. They are usually introduced in the production of the substrate from which the security element is made, usually a paper. Watermarks are easily recognizable when the security element is viewed through transmitted light, since they modify the opacity of the substrate. As a rule, in the production of the paper, the thickness of the substrate is varied, so that a reduction in thickness leads to an opacity reduction.
  • watermark colors which also locally modify the opacity of the substrate.
  • Watermarks are formed in the substrate during the production of the starting material for the security element, for example in the production of a banknote paper. Due to tolerances in tool production the round screen required for watermark generation, tolerances in watermark production in the paper machine, and variations in the cutting process of a paper substrate, paper sheets usually have variations in the position of the watermark, which are in the millimeter range. Therefore, it is difficult to arrange security features, eg printed elements in exact position to the watermark, so to pass.
  • a watermark can be used as a mask for laser radiation to pattern a layer printed on the watermark.
  • a laserablatierbare printing layer can be arranged above the watermark, and the opacity variation, which has the watermark, serves to ablate the print layer structured in the exact register to the watermark.
  • this approach has the disadvantage that the contrast curve of the watermark is converted into an identical contrast profile for the security feature. In the case of ablation, the print layer is ablated where the watermark is lighter, and not ablated where the watermark is darker.
  • the invention is therefore based on the object of specifying a method with which a security element is generated, in which a security feature in the register is a watermark, without any definition of the contrast course of the watermark.
  • a substrate which has a front and a back, at least for certain radiation is translucent and has a watermark, which modulates the opacity of the substrate and which has a certain range has applied to the front of a printing element, which covers the particular region of the watermark and is modifiable by means of the particular radiation, and the substrate is irradiated from the back with the particular radiation, wherein the particular region of the watermark with respect to the modification of the printing element as Mask is used and the printing element is modified in the register to the watermark, wherein the particular area of the watermark formed structured is that the modified printing element forms an alignment structure, in a subsequent process, a security feature is applied to the substrate, wherein the position of the Justier Modell detected and taken into account and the security feature is adapted to the position of the Justier Modell and thus arranged to the watermark.
  • the invention is based on the concept of WO 2013/0124059 A1 on, which can generate a printing element in the register to a watermark.
  • the watermark is now designed in a certain range so that the pressure element forms an alignment structure after the modification. This is then used as the basis for a subsequent process for applying a security feature to the substrate.
  • the security feature can be adapted to the position of the adjustment structure and thus ultimately to the watermark, without any limitation with respect to the security feature.
  • the security feature it is no longer limited to the effect that the security feature must be designed as a printing element and imperative to emulate the contrast of the watermark.
  • the modified printing element forms an adjustment structure that is significantly more contrast-rich than an evenly high-contrast, ideal watermark. The problem that the location of a watermark is very difficult to determine avoids the invention so.
  • a motif is printed as a security feature.
  • registration is made for the alignment structure so that the motif in the perfect register is part of the watermark without any binding to the contrast of the watermark with respect to the printed motif. Since the position of the Justier Vietnamese is detected before printing the subject, it is possible in a development to make the motif so that the Justier Vietnamese overprinted when imprinted or supplemented. In both cases, it is then no longer recognizable to a viewer in the original form which they had as an adjustment structure.
  • the subsequent process comprises application of a laser-modifiable coating and a motif is produced by irradiation of laser radiation, which modifies the coating in the form of the motif.
  • a motif is produced by irradiation of laser radiation, which modifies the coating in the form of the motif.
  • the security feature which is generated by evaluating the position of the alignment structure in the perfect register to the watermark is, as already mentioned, not limited to that printing techniques are used. It is also possible to apply a film element or, more preferably, to use a laser beam cutting process. In the latter case, the adjustment structure can be cut out and thus removed with particular preference. This is possible since the position of the alignment structure is determined before the start of the laser beam cutting process. The adjustment structure itself is therefore no longer needed in the process and after the process.
  • various processes for applying a security feature can be combined, in particular printing, and / or laser beam cutting and / or the application of diffractive structures and / or the application of holographic structures. If the security feature covers, supplements or removes the adjustment structure, this is preferably done in the last process step in the case of several processes for generating the security feature. However, this is not mandatory since, upon removal of the alignment structure within the several processes, the further referencing for the following processes is, of course, also due to the results the previous processes can be aligned. For example, when combining a printing process and a laser beam process, it is possible to overprint the alignment structure with the printing process and to align the positional orientation for the following laser beam process on the printed motif. The same applies if first a laser beam cutting is performed, which cuts out and removes the Justier poetic. Subsequent processes can then be aligned with the results of the laser beam process, ensuring perfect registration within the security feature and the watermark.
  • the particular shape of the watermark ultimately dictates the shape of the alignment structure.
  • the shape of a Justiernches is preferred.
  • the alignment structure may be in the form of a negative structure, i. be formed as a light structure against a dark background.
  • the ablation of the pressure element can preferably be carried out.
  • the adjustment structure it is possible to design the adjustment structure as a positive element, i. dark against light background.
  • indirect ablation methods as described below, can be used.
  • the invention utilizes the fact that the energy of radiation is attenuated by the substrate.
  • the more opaque (eg thicker) the substrate the stronger the attenuation. Therefore, the property of the watermark to modulate the opacity (eg, thickness) of the substrate is used to advantage.
  • the watermark is used in the specific area as a mask by a pressure element is used, which is modifiable by certain radiation for which the substrate is translucent, and that certain radiation is irradiated from the back of the substrate to the front side, on which the printing element is applied overlying the watermark.
  • the modification of the printing element to the Justier Modell which automatically lies in the perfect register to the watermark.
  • a modification of the pressure element is in particular an ablation in question when a pressure element is used, which is ablatierbar.
  • a pressure element which is ablatierbar.
  • any suitable modification of a printing element can be used.
  • This modification can be done directly, ie by direct action of the particular radiation on the printing element, or indirectly.
  • the particular radiation modifies an element, which in turn is used to modify the pressure element, which is perceivable on the front side.
  • a layer can be modified which influences the adhesion of the pressure element on the front side.
  • the printing element is then removed in the areas in which the layer has been modified (or not modified in the inverse case). The procedure is similar to the principle of the so-called wash color.
  • a further possibility for indirect modification is the modification of a developer layer which, in interaction with a developer or fixing medium, modifies the printing element at those points at which the developer layer has been suitably exposed.
  • Indirect influence of the pressure element is also possible in a two-stage process if the pressure element has an adhesive layer, which is applied to the front and exposed from the back with the participation of the watermark as a mask.
  • a color layer of the printing element can then be applied, which adheres only to those places where the exposure took place.
  • the exposed adhesive layer can also be acted upon here in an intermediate step so that it remains only in those areas in which a suitable exposure took place (positive effect) or remains in those areas in which no suitable exposure took place (negative effect).
  • pressure element is understood to mean an element applied to a substrate, which optionally, after further processing, realizes a visually or mechanically evaluable element.
  • printing elements based on printing inks. As far as this description speaks of a printing ink, this is to be understood by way of example for a printing element.
  • printing element or “printing ink” and the application of this printing element is mentioned on the front over the watermark, it is also included that applied by a printing element layer system, only a part of the layer system and is exposed to the specific radiation; the other part is then applied after these steps and interacts with the exposed portion of the layer system to create a printed image in the watermark to the watermark.
  • printing element thus also means a multilayer system, wherein a part of the layer system is applied to the front surface before the exposure and then illuminated with the specific irradiation becomes. Another part of the layer system is then applied only after the exposure.
  • banknotes watermarks are common, which modulates the opacity of the substrate by varying a thickness of the substrate at a constant density of the substrate, since such watermarks are usually very difficult to emulate.
  • These watermarks are well suited for the process of the invention.
  • a watermark that modulates the opacity of a substrate can also be generated by a so-called watermark color, rather than by varying the thickness of the substrate.
  • the watermark color causes a reduction of the scattering of light in the substrate core. Basically, scattering is due to a large number of interfaces of fibers, fillers, glue, etc. to the surrounding air. These ambient airborne interfaces are significantly reduced by suitable binder components in the watermark ink, thus decreasing opacity in these areas.
  • a binder component is, for example, glycerol, which penetrates into the substrate and remains in the pores of the substrate. The same applies analogously if the watermark is caused by a coloration which modulates the opacity of the substrate.
  • the printing ink comprises one or more of the following substances: an optically variable color, a magnetically orientable color, a metallic color, a color which is effective in the non-visible spectral range.
  • the term "certain radiation” used in this description therefore expresses that a pressure element is used which is modifiable by means of this radiation.
  • the modification for example in the form of an ablation, is achieved when the particular radiation at the front has a suitable intensity.
  • the opacity modulation caused by the watermark reduces the intensity of the radiation on the front surface on which the printing element is located.
  • the radiation intensity on the back side is therefore adjusted so that the opacity modulation, which is caused by the watermark, leads to a radiation modulation on the front side, which modulates the modification effect on the printing element.
  • the radiation intensity at the backside is chosen so that at the places where the watermark causes the lowest opacity in the substrate, a modification of the printing element occurs at the places where the watermark causes the highest opacity of the substrate, however, no or only a very slight modification is achieved. Then, the watermark serves as a mask in the irradiation of the substrate with the specific radiation. Since the modification of the printing element usually requires a relatively high radiation intensity, the use of a beam is advantageous, which is rastered over the back of the substrate.
  • ink used here stands out for the printing effect achieved by the watermark-masked and radiation-based modification.
  • the printing ink itself can also comprise structures, which go beyond conventional color systems, such as a foil coating or metallization.
  • Items to be protected within the scope of this description may include, for example, security papers, identity and value documents (such as banknotes, chip cards, passports, cards, identification cards, identity cards, stocks, bonds, certificates, vouchers, checks, tickets, credit cards, health cards,. ..) as well as product security elements, such as Labels, seals, packaging, be.
  • identity and value documents such as banknotes, chip cards, passports, cards, identification cards, identity cards, stocks, bonds, certificates, vouchers, checks, tickets, credit cards, health cards,. ..
  • product security elements such as Labels, seals, packaging, be.
  • security paper is understood here in particular as the precursor that can not yet be processed to form a value document (eg a card) which, in addition to the pressure produced according to the invention, can also have further authenticity features (such as luminescent substances provided in the volume, for example).
  • value documents here on the one hand from security papers produced documents, eg. B. banknotes understood.
  • value documents can also be other documents and articles which are processed with the printing method according to the invention, so that the value documents have non-copyable authenticity features, whereby an authenticity check is possible and at the same time unwanted copies are prevented.
  • the substrate is particularly preferably made of paper made of cotton fibers, as used for example for banknotes.
  • the substrate may also be made of paper of other natural fibers, also preferably of synthetic fibers, ie a mixture of natural and synthetic fibers.
  • the substrate consists of a combination of at least two superimposed and interconnected different substrates, a so-called hybrid. It may be, for example, a combination of plastic film paper or even a three-layer composite, such as plastic film-paper plastic film, ie a paper substrate is covered on either side by a plastic film, or paper-plastic film paper, ie a substrate a plastic film is covered on both sides by a paper substrate.
  • the substrate consists of an at least partially transparent plastic film.
  • the watermark is generated in this case by a color which is applied to one side of the substrate and whose hue is at least similar to the hue of the substrate.
  • a watermark is for example off DE 10 2009 056 462 A1 known.
  • the reciprocal property of translucency is opacity. As far as there is talk here that a watermark modulates the opacity, it can equally be said that it inversely modulates the translucency.
  • Fig. 1a shows in a sectional view of a security element 1, wherein for simplicity, only a substrate 2 is drawn.
  • the substrate 2 has a front side 3 (which is arranged below in the figures without further restriction) and a back side 4.
  • a watermark 5 is incorporated, which modulates the thickness of the substrate 2 and thus its opacity.
  • This opacity modulation is in 1b shows which shows a plan view of the front side 3 of the substrate 2 schematically.
  • the substrate 2 has a medium opacity.
  • the substrate 2 has a low opacity or a high translucency.
  • the paper thickness can also be increased by embossing. This can be used for branding. The brand is then pronounced as a thin spot, the environment of the brand as a thick spot. The mask effect for the laser is enhanced in such an embodiment.
  • a security feature for example a printed image and / or a laser beam cutting area and / or a film element and / or a diffractive structure and / or a hologram is to be generated in registration to the watermark which lies in perfect registration with the watermark , To accomplish this, first an alignment structure is created which is fitted to the watermark.
  • Fig. 2 shows the substrate 2 with applied on the front side 3 ink 9.
  • the ink 9 is not structured (yet), but at least partially covers a certain area 13 in which the watermark 5 is present in the substrate 2.
  • a laser beam 10 is now guided over the substrate. It passes through the substrate 2.
  • the wavelength of the laser beam is such that the ink 9 absorbs the radiation.
  • the laser beam 10 becomes dependent of the opacity of the substrate 2, which is modulated by the watermark 5 attenuated.
  • the laser beam 10 is greatly attenuated.
  • the laser beam is least attenuated.
  • Fig. 2 This is schematically illustrated by the thickness of the laser beam 10. In fact, of course, only the intensity of the laser beam 10, but not its radiation cross section when passing through the substrate 2 is attenuated.
  • the intensity of the laser beam 10 is adjusted so as to give a modulation of the ablation effect that the laser beam 10 has on the printing ink 9 applied to the front side 3: in the area 8 with low opacity, the printing ink 9 is ablated a maximum, in areas 7 with medium Opacity, the ink is ablated to a lesser degree, and in areas 6 with maximum opacity, the least or possibly even no ablation occurs.
  • a laser-sensitive ink can also be discolored.
  • the laser-sensitive ink only discolors in areas of low opacity.
  • the watermark is formed in the specific region 13 so that after the ablation of the printing ink 9, an alignment structure is produced, which is embodied purely by way of example in the form of at least one adjustment cross 14 in subsequent figures.
  • This adjustment structure forms the local referencing for subsequent processes for applying a security feature, which then lies in the perfect register for the watermark 5.
  • the described embodiment can be modified such that instead of the watermark 5, which modulates the opacity by a thickness variation of the substrate, a so-called “false” or printed watermark 11 occurs, ie a watermark, which generates on the substrate 2 by a so-called watermark color has been.
