Security element with machine-readable features
A security element has machine-readable magnetic security features in the form of at least two magnetic materials which have different magnitudes of coercive force and which are provided as a mixture in at least one printing ink that is applied onto a carrier substrate, wherein the at least one printing ink is provided in at least two regions on the security element with the same thickness and/or different thicknesses, and a defined mixture ratio of the at least two magnetic materials with different magnitudes of coercive force is provided in the at least one printing ink.
1. A security element ( 18 ) with machine-readable, magnetic security features ( 3 , 4 ) in the form of at least two magnetic materials of different coercivity, which are present as a mixture in at least one printing ink ( 2 ), which is applied to a carrier substrate ( 1 ),
wherein the at least one printing ink ( 2 ) is provided in at least two regions on the security element ( 18 ) in the same and/or different thickness, and a defined mixing ratio of the at least two magnetic materials ( 3 , 4 ) of different coercivity is present in the at least one printing ink ( 2 ), and
wherein at least two printing inks ( 2 ) having respectively different mixing ratios of the at least two magnetic materials ( 3 , 4 ) are provided in at least two areas of the carrier substrate ( 1 ) in an identical and/or different thickness.
2. The security element ( 18 ) according to claim 1 , wherein the at least two magnetic materials ( 3 , 4 ) are a high-coercivity magnetic material and a low-coercivity magnetic material.
3. The security element ( 18 ) according to claim 1 ,
wherein a plurality of magnetic regions are formed on the carrier substrate ( 1 ), and
wherein each magnetic region is formed by exactly one printing ink ( 2 ) and adjacent magnetic regions have different printing inks.
4. The security element ( 18 ) according to claim 1 , wherein a plurality of identical and/or different printing inks ( 2 ) are arranged directly adjacent to one another on the carrier substrate ( 1 ) and thus form a magnetic region group.
5. The security element ( 18 ) according to claim 4 , wherein the printing inks ( 2 ) of a magnetic region group have different thicknesses.
6. The security element ( 18 ) according to claim 5 , wherein the thicknesses proceed in an increasing or decreasing manner from one side of the magnetic region group to the opposite side.
7. The security element ( 18 ) according to claim 4 , wherein a plurality of magnetic region groups are provided which are arranged at a distance from one another.
8. The security element ( 18 ) according to claim 4 , wherein a plurality of magnetic region groups are provided which are arranged at a constant distance from one another.
9. The security element ( 18 ) according to claim 1 , wherein the mixing ratio of high-coercivity magnetic material and low-coercivity magnetic material is 20:1 to 1:20.
10. The security element ( 18 ) according to claim 1 , wherein the security element ( 18 ) has a full-surface or partial opaque layer ( 5 , 6 ) on one side of the carrier substrate ( 1 ) below and/or above the printing inks ( 2 ).
11. The security element ( 18 ) according to claim 10 , wherein the opaque layer has recesses in the form of letters, numbers, characters, patterns, symbols or lines.
12. The security element ( 18 ) according to claim 10 , wherein the opaque layer is a reflective layer ( 5 ) or a colored, black or white printed layer ( 6 ).
13. The security element ( 18 ) according to claim 10 , wherein the opaque layer ( 5 , 6 ) and/or the further security features are applied true to register and/or with register accuracy to the at least one printing ink ( 2 ).
14. The security element ( 18 ) according to claim 10 , wherein the opaque layer and/or the further security features are provided on a second carrier substrate and are bonded to the magnetic regions ( 2 ) by lamination or lining with the layer structure.
15. The security element ( 18 ) according to claim 1 , wherein the security element ( 18 ) comprises further security features.
16. A data carrier or value document, comprising the security element according to claim 1 .
17. The data carrier or value document according to claim 16 , wherein the security element ( 18 ) in the form of a thread, strip or patch is at least partially embedded in the data carrier or value document or applied to the data carrier or value document.
18. The security element ( 18 ) according to claim 1 , wherein the at least two areas are spaced from each other.
