Definitions
- the invention relates to a data carrier, in particular a security, an identification card or the like, which is provided with an optically variable security element which has optically variable pigments without or with only a weak body color.
- EP 0435 029 A3 also discloses the use of liquid-crystalline polymers as optically variable elements, in which a color shift effect occurs when the viewing or illumination angle changes. This effect is based essentially on the helical structure of the liquid-crystalline phase, which is fixed in polymers by crosslinking and, moreover, via external conditions, such as, for. B. the mechanical pretreatment, can be adjusted. This means that the color of the color change can also be specifically adjusted.
- the object of the invention is to propose a data carrier and a method for its production which have a new optical effect and thus an increased protection against counterfeiting.
- the invention is based on the basic idea that the document first with information contrasting to the data carrier, such as. B. is provided with a finely structured print. This information is then provided with an optically variable effect, a translucent layer having an optically variable effect being applied at least over a portion of the information.
- translucent, optically variable layers can be used which have optically variable pigments with no or only a small body color.
- other translucent optically variable layers can be used, such as. B. interference layer structures or optically variable films such as liquid crystalline silicone polymer films.
- the layer having an optically variable effect can be applied in the context of the invention by coating, transfer printing, other application, application of a film or printing.
- the invention is described using the example of printing, however the other techniques mentioned above can also be used analogously to apply the optically variable layer.
- the method according to the invention makes it possible to provide this information with an optically variable effect.
- the information is at least partially provided with a translucent, optically variable layer, which has, for example, an optically variable pigment without or with only a small body color.
- the lack of their own body color in the optically variable pigments makes these pigments particularly effective in those places where the first printing ink is on the data carrier as a structured background.
- the optically variable effect is not or only barely visible at those places where there is no background pressure.
- the width or fineness of the structures which can be produced is limited and is considerably higher than the line thicknesses which can be achieved with conventional pigments, since the optically variable pigments are essential in comparison with the conventional pigments are larger and therefore information as a high-resolution structure cannot be produced by directly printing on the pigments.
- the optically variable pigments can no longer be printed from a certain mesh size of the screen, so that the generation of a high-resolution structure using this technique is impossible.
- the advantage of the invention is therefore that the document is provided with a high-resolution fine structure, which moreover has a previously unknown optically variable effect for the viewer.
- the procedure according to the invention offers the further advantage that the formation of the fine structure and the formation of the optically variable effect are decoupled from one another, so that the pigments optimized for the particular application can be used for the desired effect.
- FIG 9 shows an embodiment of the optically variable security element according to the invention.
- FIG. 1 shows a data carrier 1 according to the invention, in the present case a bank note, with a security element 2 attached to it.
- This security element 2 is positioned at a suitable location on the data carrier, so that its optical effect on the one hand makes it easy to check the data carrier and on the other hand to prevent counterfeiting and leads here in particular with color copiers.
- the optically variable element 2 shows an enlarged detail of the data carrier 1 according to the invention in the region of the optically variable element.
- the optically variable element 2 consists of an imprint of lines 3 in a color that contrasts with the data carrier. For example, this can be a fine, high-resolution line pattern.
- the substance with the optically variable pigments is applied in an area 4 via these lines 3.
- Inks that are optically variable are particularly suitable Contain pigments and be printed on the surface. Outside the printing lines 3, the optically variable pigments in the area 4 cannot be recognized, or can only be recognized with extreme weakness, because of the lack of one's own body color.
- the effect of the optically variable pigments comes into its own on lines 3, so that an optically variable effect is superimposed on the high-resolution print pattern, which effect can only be clearly seen in the areas of the print pattern.
- the lines 3 of the structure can be adapted to the respective requirements.
- dark colors in particular allow the overlying flat print 4 of the optically variable pigments to be particularly effective.
- the high-resolution structure 3 can vary in color and / or in the respective color tones.
- the lines 3 in their entirety, as shown in FIG. 3, with a printing ink which contains optically variable pigments.
- This makes it possible to transfer the total information content of the image, logo, sign or the like generated by the structuring of the first imprint to the optical effectiveness of the optically variable pigments above it.
- the structure of the first printing ink eg. B. as a halftone image
- the iridescent effect of the optically variable pigments printed on is determined by the color and / or intensity value of the high-resolution structure underneath.
- the data carrier 1 can also be designed in such a way that a high-resolution line structure that is present on the data carrier is used to generate the optically variable element.
- High-resolution print lines 5, which are designed, for example, as guilloches or high-resolution lines of an image motif, can be overprinted with the optically variable color pigments at least in a partial area.
- the area 4 represented by the overprint can be designed as a geometric shape or as a character, so that the background pressure lines 5 in the area of the overprint 4 produce an optically variable overprint with a tilting effect.
- FIG. 5 shows a data carrier 1 which has an optically variable security element 2.
- the again printed, possibly high-resolution structure 3 is covered in the area 4 by optically variable pigments by a printing ink applied over a large area.
- a further piece of information 6 is introduced within the area 4, which in the present case is represented by the letter “A”.
- This information can be generated in the surface 4, for example by embossing or printing. When embossing, both the conventional gravure printing processes with and without color come into consideration.
- embossing both the conventional gravure printing processes with and without color come into consideration.
- the printing color of the print 6 can, however, also be selected from the group of transparent or translucent colors, so that the optically variable background 4 is retained in the area of the information 6, but is modified in comparison with its immediate surroundings.
- FIG. 6 shows a further example of the data carrier 1 according to the invention, on which an optically variable element 2 is applied.
- the again existing lines 3 of the first printing ink, which can be printed in one or more colors, are covered by several individual areas 7, 8, 9 and 10.
- the individual areas 7 to 10 are produced by printing on a color containing an optically variable pigment, the pigments in turn being recognizable in the areas in which the high-resolution structure 3 runs beneath them.
- the individual areas 7 to 10 can contain different optically variable pigments and thus each produce a different impression on the viewer.
- the optically variable areas 7 to 10 already carry an information content which, in the simplest case, consists of a specific color sequence. This information content is then influenced or only made visible by the structure of the first print, which is under the optically variable colors.
- the optically variable element according to the invention can also be combined with the back of the document, so that a complete information appears in the review.
- the optically variable element 2 is applied to a data carrier 1, with a structured imprint in one first being in turn on the data carrier first, any desired printing ink is applied.
- This is printed in area 4, which in the present case is letter C, with the optically variable color.
- elements 11, 12, 13 are introduced by embossing or printing in such a way that they can be seen in the reflected light.
- the back of the document is printed or embossed in the area of the optically variable element 2 so that two elements 14 and 15 can be seen in transmitted light, which together with elements 11, 12 and 13 when viewed in transmitted light there is additional overall information.
- the security element according to the invention can be combined with a combination of an embossed structure known per se from CA 1 019 012 with an embossed line pattern to form an overall element which has completely new properties.
- the optically variable element 2 applied to the data carrier 1 consists of several components. First lines 16 of a first high-resolution structure are printed. In the area of this printed structure, other lines 17, a second high-resolution structure, are then printed, which differ from the first one in their color, shape or the direction of the printed lines.
- the second applied high-resolution structure 17 forms a first part of information introduced into the optically variable element, in the following case the lower part of the number "10".
- Another surface area of the optically variable element is now known from those known per se from CA 1 019 012
- a combination of an embossing and a line pattern is formed, with lines being printed which can be recognized differently in the area 18 due to an additional embossing when viewed at different viewing angles.
- the non-embossed area 19 is covered over the entire area with a substance, in particular a printing ink, which in turn has an optically variable pigment without or with only weak own body color. Lines 16 and 17 of the optically variable element thus have a viewing angle-dependent color impression.
- the part 18 of the optically variable element contains the partial information which is complementary to the imprint 17 and which is applied in register-correct manner and, because of the embossing and the line pattern, is only clearly visible under certain viewing angles.
- the partial information 17 is thus visible from all viewing angles, but a different color effect is generated depending on the viewing angle.
- Part 18 of the optically variable security element contains the supplementary partial information, which, however, is only clearly visible when the data carrier is tilted.
- FIG. 9 shows a further example of a data carrier according to the invention.
- a high-resolution portrait consisting of fine lines 20 is first printed on a data carrier 1 using the steel gravure printing method.
- the identical image in coarser resolution ie for example in wider lines 21 is completely or partially superimposed on this steel intaglio portrait, optically variable colors being used for the second image, so that the high-resolution steel engraving in this way an optically variable effect is assigned.
- the technology described last offers the possibility of using less optically variable To assign all colors to the steel engraving portrait an optically variable impression.
- the embodiments based on the basic idea of the invention lead to a large number of specific design options. These in turn can also be combined with one another or with other already known optical security elements for data carriers.
- a suitable printing ink can be applied to produce the first structured imprint.
- etching techniques are available, but other methods, such as the laser ablation method, can also be used.
- the generation of the structure with the aid of a laser can also be regarded as printing in this context.
- the print can be high-resolution, single-color or multi-color and each with different color tones.
- the structure is generated as a line pattern, dot pattern, halftone image or the like.
- the brilliance of the optically variable effect can be increased further by smoothing the background before or after the application of the optically variable colors.
- the high-resolution fine structure can also be applied as a so-called “negative structure”, in which a fine line structure is produced by means of a cut-out from an otherwise full-surface print, in addition to the straight lines also others such as guilloches or Microprint images of alphanumeric characters can be generated, which are then overprinted with the optically variable colors.
- optically variable colors can be used, which contain one, several and / or also different optically variable pigments, such as liquid crystalline silicone polymers or iridescent pigments.
- the color with which the structure is produced can also be matched to the color of the optically variable pigments applied to it, so that at certain viewing angles the color of the optically variable element and the color of the background are the same.
- the optically variable substance or color, which is applied overlapping in a region of the structure contains optically variable pigments which have little or no body color of their own, such as in particular interference layer pigments or pigments produced on the basis of liquid-crystalline polymers. They can be printed on the respective structures produced by the first printing ink in such a way that they cover the entire surface, even overlap them or only cover a part of the structure in certain shapes, characters or patterns.
- the method according to the invention is not restricted to the fact that the optically variable element is generated directly on the data carrier. Rather, it is also possible to produce the optically variable element on a separate carrier and then to transfer the element to the data carrier using one of the known transfer methods.
- the optically variable element can also be implemented as a printed, optically variable film, in particular provided with a fine line print.
