  • the electrically conducting tracks can be made of any electrically conducting material, but the use of copper tracks has proven of particular advantage.
  • the security document of the present invention also comprises at least one magnetic means.
  • Magnetic means are well known in the art and refer to materials, which exert an attractive or repulsive (magnetic) force on other materials. Some well-known materials that exhibit easily detectable magnetic properties are iron, some steels, and the mineral lodestone.
  • Magnetic forces are fundamental forces that arise due to the movement of electrical charge. Maxwell's equations describe the origin and behaviour of the fields that govern these forces. Thus, magnetism is seen whenever electrically charged particles are in motion. This can arise either from movement of electrons in an electric current, resulting in “electromagnetism”, or from the quantum-mechanical orbital motion and spin of electrons, resulting in what are known as “permanent magnets”.
  • the physical cause of the magnetism of objects, as distinct from electrical currents, is the atomic magnetic dipole.
  • Magnetic dipoles, or magnetic moments result on the atomic scale from the two kinds of movement of electrons. The first is the orbital motion of the electron around the nucleus; this motion can be considered as a current loop, resulting in an orbital dipole magnetic moment along the axis of the nucleus.
  • the second, much stronger, source of electronic magnetic moment is due to a quantum mechanical property called the spin dipole magnetic moment.
  • the overall magnetic moment of the atom is the net sum of all of the magnetic moments of the individual electrons. Because of the tendency of magnetic dipoles to oppose each other to reduce the net energy, in an atom the opposing magnetic moments of some pairs of electrons cancel each other, both in orbital motion and in spin magnetic moments. Thus, in the case of an atom with a completely filled electron shell or sub shell, the magnetic moments normally completely cancel each other out and only atoms with partially-filled electron shells have a magnetic moment, whose strength depends on the number of unpaired electrons.
  • the differences in configuration of the electrons in various elements thus determine the nature and magnitude of the atomic magnetic moments, which in turn determine the differing magnetic properties of various materials.
  • the magnetic behaviour preferably results from Diamagnetism, Paramagnetism, Molecular magnetism, Ferromagnetism, Antiferromagnetism, Ferrimagnetism, Metamagnetism, Spin glass and/or Superparamagnetism.

  • the magnetic means comprise at least one Heusler alloy, i. e. a ferromagnetic metal alloy whose constituents are not themselves ferromagnetic in their pure forms.

  • the term "overt feature”, as used herein refers to a feature can be simply verified by a member of the general public using just the feature itself, and with no requirement for additional apparatus.

  • the deposition technique that is considered to be most suitable for the intended application is printing, wherein offset printing, flat bed screen printing, rotary screen printing, tampo, flexo printing, gravure and/or inkjet printing are particularly preferred.
  • the offset printing works by transferring an ink onto an imaged metal cylinder, which is then passed over a water roller.
  • the ink repels the water, keeping the image on the cylinder sharp. This is then transferred onto an offset cylinder and then onto the substrate.
  • Particularly preferred cylinders are made by a lithographic process.
  • the process is preferably reel-to-reel but can also be sheet fed.
  • Screen-printing is a process in which a high viscosity ink is squeezed by a squeegee blade through a patterned mesh onto a substrate to form an image.
  • Preferred screen printing meshes are made from PET or Nylon although steel is also usable.
  • the screens are made by painting the entire mesh with a UV-curable polymer.
  • the required artwork is then printed onto a film as an opaque image. This is placed over the mesh as a mask and the whole screen is exposed to UV light. Where the paint is exposed to the UV it cross-links and hardens, filling the holes in the mesh.
  • the ink behind the mask, which has not been exposed, is then washed out, leaving the image on the screen.
  • the resolution of the image is governed by the cross-sectional area and profile of the mesh, the blade pressure and the particulate loading of the ink.
  • Screen printing inks can vary from those used for graphics, which have a nanometre-size pigment dispersion, to those containing 10 micron plus silver flake. To achieve a high resolution image a large pigment size must be avoided to prevent the mesh filtering the ink.
  • the profile of the mesh in conjunction with the blade pressure governs the thickness of deposit for a given ink. If too high a profile is used, the thickness of ink deposited can be too great, which can cause the ink to slump, thereby reducing the image quality.
  • Rotary screen-printing is essentially the reel-to-reel version of flatbed screen-printing with the image being produced on a patterned cylindrical mesh rather than a flat mesh.
  • an image is produced on a rubber stamp onto which ink is transferred.
  • the image is then printed onto the substrate.
  • the material the stamp is made from dictates the resolution of the printed image.
  • Engraved metal plates can be used but preferably a stamp is made from a photo-imageable rubber compound.
  • the image is created in the same way as for the tampo process, but the difference is that it is wrapped around a metal cylinder to act as a roller. Ink is transferred to it by means of a second roller and then onto the substrate.
  • gravure is another high-speed reel-to-reel process. It is used instead of the flexo process when high volumes of high-resolution images are required.
  • a steel cylinder is etched to produce the image roller.
  • inkjet printing is broadly used to describe any digitally-controlled printer, although it originated from the first piezo-electric driven inkjet heads.
  • a voltage is applied to a piezoelectric material, which surrounds a compressible ink chamber, firing the ink out of the chamber nozzle.
  • the ink chamber relaxes, drawing more ink into the chamber from a reservoir to refill it.
  • Bubble-jet technology is similar to the piezo-electric inkjet, the difference being that the bubble-jet uses heat to expand the ink and fire it out of nozzle.
  • the ink In continuous inkjet printing the ink is pumped continuously through the printer under pressure.
  • the ink is electrically charged and as it is fired, the flight of droplet is controlled electro-statically.
  • Laser scribing can be used for scribing extremely fine features.
  • the process uses a laser to cut away copper to form an image, this is known as ablation.
  • the cut produced by the laser leaves a jagged edge behind it as well as debris from the oblation process.
  • the magnetic means is preferably moved across the surface of the coil and a status change of the electronic security means is observed. Thereby a voltage is generated in the coil that operates the electronic security means.
  • the gap between the surface of the coil and the magnetic means is preferably as low as possible, particularly smaller than 5 mm, more preferably smaller than 2 mm, even more preferably smaller than 1 mm, and most preferably within the range of 0.01 mm to 0.5 mm.
  • the velocity of the movement of the magnetic means parallel to the surface of the coil is preferably at least 0.1 m/s, very preferably at least 0.5 m/s, most preferably at least 1 m/s.
  • the magnetic means that is passed over the coil will have a North pole and a South pole. As such, both a positive voltage and a negative voltage will be induced in the coil with a single swipe of the magnet past the coil.
  • the exact nature of the voltage profile with position of the magnet will depend on the orientation of the magnet poles with respect to the coil axis. This is a useful feature of the present invention since the change from positive to negative voltage potential can also, if the display is configured appropriately, cause a change in the image state of the display.
  • Fig. 1 is a plan view of said particular preferred embodiment wherein the thickness of the elements is greatly exaggerated for clarity.
  • the security document comprises a thin flexible substrate 1 and a thin flexible coil 3 deposited or printed onto said substrate 1. Both ends of the coil is electrically connected, via flexible electrically conducting tracks 5, which may be printed or deposited on the substrate 1, to a thin and flexible low power display 2.
  • the display 2 may be printed or deposited onto the substrate or adhered to the substrate before or after the printing and/or deposition of the other components of the feature. In any case, electrical connectivity is made between the display 2 and the coil 3.
  • the security document also comprise a magnetic means 4 also printed or deposited on the substrate 1. Thereby the coil 3 and the magnetic means 4 are located on the same side of the substrate. Furthermore the coil 3 is designed such that the movement of the magnetic means 4 over the surface of the coil 1 generates sufficient electric voltage and current to operate the display 2.
  • two coils 1 could be utilised in which both coils are electrically connected to the display 2. These coils 1 could be printed on top of each other or adjacent to each other. The direction of the windings in the different coils 1 could be the same or reverse. The winding direction will determine the polarity (positive or negative) of the generated voltage for a given positive or negative rate of change of flux. A plurality of coils 1 with different winding directions may be used.
  • both the coils 1 and the magnetic means 4 in such a way, with features that may be hidden from normal detection (such as position and orientation of the North and South poles in the magnetic means 4 and direction of electrical winding in the coils 1) to give rise to a specific voltage profile when the magnetic means 4 is swiped past the coil 1, which in turn gives rise to a specific pre-determined changing optical image within the display 2.
  • Fig. 2 is a perspective view illustrating the use of security document for checking its authenticity. Thereby the substrate 1 is folded and the magnetic means 4 is moved across the surface of the coil 3 and a status change of the display 2, i. e. the electronic security means is observed.
