Definitions
- the invention relates to a method and a device for producing colored surface structures using interference in certain wavelengths which result in clean colors, or by producing so-called structural colors and the products produced therefrom.
- the surfaces are produced with stamps and rollers in the nanometer range.
- Such methods and products are known, for example, from the one ounce silver dollar from Australia.
- the Australian silver dollar is provided with a colored kangaroo, see FIG. 7.
- colored surfaces such as that of the silver dollar are applied by applying pigment-containing paints or similar layers. The disadvantage of this is that such surfaces last a long time behind glass, but not in everyday use, such as in a wallet.
- the invention uses the physical principle of interference. These structural colors are due to interference and can be observed in special butterflies and peacock species. The light refracts at the diffraction grating structures and produces an overall color that can be different after the light has entered.
- the aim of the invention is now to produce such surfaces by embossing. This embossing process is used in particular for coins and stainless steel sheets, for jewelry, in the automotive sector.
- the diffraction effect similar to the colors of the butterfly wings and the peacock feather is now imitated in the form of an embossed structure to be created, which creates a diffraction grating.
- the negative structure of FIG. 1, for example, is now reproduced on the embossing stamp.
- the distance between the cross grids determines the color.
- the embossing stamp preferably penetrates into the surface approximately A of the width.
- the area of the inner grille swallows the rest of the color and appears somewhat velvety, ie the grille matrix is bare, the inner part is rough. This reflects the desired color, swallowing or absorbing the non-preferred color.
- Monolithic materials are preferably used for embossing, since they do not have a crystal structure with grain boundaries that are larger than the wavelength of the light spectrum of the respective color to be embossed.
- Monolithic materials include diamonds and monolithically grown quartz. However, the hardness of the diamond is an advantage. Blue diamonds are electrical semiconductors and can be cloned using EDM processes with master electrodes. The clone stamp is made as a master stamp in negative. With this, several working stamps can be made.
- Monolithic semiconductor crystals can be used as the clone electrode. Quartz crystals are preferably used as actuators for the production of the master electrodes. See Pl-Physik Instruments catalog. These are controllable in the nano range.
- the embossing process for the production of colored surfaces or for the production of so-called structural colors takes place without the introduction of color pigments, but rather by means of permanent plastic surface deformation, which is shown by way of example in FIG.
- a rib structure is shown in high magnification, which generates the iridescent interference colors as a step grating with the aid of incident light, which is represented by the arrows.
- the hallmark is made from monolithic crystals, especially by laser processing.
- Rolling monolithic diamonds in the "egg" by methane deposition creates the diamond shell and is deposited as a roll.
- the monolithic diamond shell is nano-corrugated by laser processing.
- the hard surface of the embossing die or the roller penetrates into the counter material with the structure in the surface so that it is permanently plastically deformed. Single crystals are permanently deformed above the recrystallization temperature under protective gas.
- the die or its movement is regulated by quartz in such a way that the depth of penetration does not destroy the crystal.
- a press is used for macro embossing.
- the monolithic stamp is preferably made of diamond. Images are created by arranging the diamond stamps in Tiffany style. The dies are used with elastic intermediate shafts to limit the pressing force.
- FIG. 4 shows a system for keeping the pressing force constant, with embossing surface 1, solder socket 2, diamond carrier 3, seal 4, stamp carrier 5, diamond 6, reservoir 7, check valve 8, priming pump 9 and oil cushion 10.
- the basic color is compensated for by the phase shift of the wavelength and the resulting interference.
- the stamp is preheated in such a way that the surface of the material to be stamped is warmed up so that the material is deformed above the recrystallization temperature.
- a monocrystalline diamond is laser soldered with cobalt.
- the phase shift of the interference grating is adapted to the base material so that the desired color to be generated is generated.
- the star is stamped into the recess to increase the security against counterfeiting and thus protected against being scratched.
- This is called protective embossing.
- the depression is preferably arranged in such a way that the smallest coin of a currency, as in the present example, cannot penetrate the 1 cent coin into the depression, since a protective shoulder prevents this, as shown in FIGS. 5 and 6.
- micro cross tables are used. B from Pl.
- the dies are electrostatically micro-coated for cleaning and lubrication with nano-particles made of colloidal Teflon.
- the post-cleaning is carried out in an ultrasonic bath with water.
- an original butterfly wing with structural colors or a peacock feather (Vanessa lo) is scanned in such a way that it is increased by the depth of penetration of the elastic deformation and then removed by laser or electrical ablation.
- the animals should preferably only be anesthetized and therefore not have to be killed.
- the surface structure is processed by magnetic removal with emery microparticles in an interferent magnetic field.
- the frequency determines the distance between the interference grating and thus the ferns of the generated wavelength.
- the wing can also be scanned with aura photography in the nano range.
- the light source is in the radiological spectrum with a wavelength of approx. 2 nm.
- X-ray photography with 5000 film. Processing takes place in a vacuum tube using electron beam grids. Material to be removed is evaporated by material evaporation.
- the embossing plate is atomically polished beforehand.
- the star or stars are stamped in a recessed hollow to prevent counterfeiting and reduce scratching, as shown in the Figures 5 and 6 can be seen.
- This hollow is also used to center the stamp.
- the embossing stamp is provided with a forger angle.
- the counterfeiting angle is used for viewing the color at a defined viewing angle z. B. 45th degree to the coat of arms perpendicular in two planes. This is shown in Figure 3.
- Creating the multi-color embossing and using a counterfeiting angle by means of several embossing processes makes the embossing process complicated and therefore extremely forgery-proof.
- the counterfeiting angle can be combined with hologram embossing and increases the security against forgery.
- the counterfeiting angle with the corresponding test device 11 automatically helps, for example at the central bank in counting devices, to check the authenticity of the coins, which is checked by means of a spectral camera and angle coding.
- the staircase of the Echelette grating is fulfilled. This creates clearer color reflections with the boundary conditions of the Echelette grating.
- the said method ensures that coins are secure against forgery when it is used or is used.
- the coin is embossed and nano-optically provided with a stamp, in particular with a structural color.
- the internal surface is protected against scratching by cantilevering stamps.
- the embossing stamp is made of electron-beam-polished monocrystal, diamond.
- Sheets especially those made from austenitic sheets, are rolled and then embossed in color.
- the embossing stamp is polished and processed on the surface with an electron or X-ray drill system. This so-called cluster sputtering is shown in FIGS. 8 and 9.
- the parameters in the CAD / CAM link are parameterized and displayed or edited in advance using a CAD system. In this way, counterfeiting is made more difficult with the euro, especially with higher values.
- the diamonds are heated on the surface. This enables deformations in the crystal structure above the recrystallization temperature of the materials.
- the net lines 90 + -5 ° are electropolished, electron beam machined, introduced.
- the cross grille is formed or machined with Fern in the spring deflection during the forming process in such a way that the color brilliance and purity are preserved.
- the entire color spectrum can be produced with multi-color printing.
- the diamond is prefabricated with certain colors and is then cut on a mother stamp, especially attached via laser soldering in the Tiffany process.
- the stamp is aligned in an image-synchronous / angle-synchronous manner by means of an optical detection system via rotary embossing stamps.
- the die or stamps are processed in the cluster sputtering system with a short-wave X-ray laser, as shown in FIGS. 8 and 9.
- the diamond or diamonds are made from SP 6 mesh.
- the diamonds are arranged at 45 ° and 90 ° because of the shear stress lines. This makes the embossing flow lines more precise.
- Advantageous further developments are contained in claims 1 to 10.
- the press mentioned in the claims is not expressly shown, it can be known presses such as are known, for example, in coin minting, for example as a so-called C press.
- the embossing die is equipped with a constant pressing force, as shown in FIG. 4.
- the constant pressing force or the force limitation protects the punches from overload and destruction.
- the embossing stamps are preferably produced by cluster sputter laser burning, ie the particularly short-wave X-ray laser is split into a particularly large number of individual beams arranged in parallel via optical or magnetic lenses. This allows the number of travel paths to be kept smaller. The multiple decomposition of the beams gives a shorter burning time and is therefore cost-saving, see Figures 8 and 9.
