Description
Vd0 2004/045866 PCT/DE2003/003806 Nano-optical Color Embossing The invention relates to a method and an apparatus for manufacturing color surface structures using interferences at certain wavelengths that produce pure colors, or through creation of so-called structure colors, as well as the products produced therefrom. The surfaces are produced through dies and rollers in the range of nanometers.
Such methods and products are, for example, known through the Australian One Ounce Silver Dollar. The Australian silver dollar is provided with a color kangaroo, see Figure 7.
Prior Art Color surfaces such as those of the silver dollar are produced through applying layers of paint containing pigments, or similar layers. It is disadvantageous that such surfaces last very long under glass, but not during daily use, for example, in a wallet. Hence, it is an objective of the present invention to avoid the above mentioned disadvantages and to provide a possibility to create an inexpensive and reliable color system together with the related products, that effectively prevent the possibility of forgery.
The invention uses the physical principle of interference. These structure colors are due to interference phenomena and can be observed on certain butterflies and peacocks. Light is diffracted at the diffraction grating structures resulting in a color that may be different depending on the incidence of light. It is one objective of the invention to produce structure colors generating surfaces through embossing.
A method that uses embossing is in particular applicable for coins and rust resistant sheet metals, jewelry, and parts used in the automotive industry. It is possible to mark any genuine spare part, any coin or any sheet metal forgery-proof with such a structure color.
Advantages with respect to conventional methods:
Paint does not need to be applied.
Paint does not need to be dried.
Coins can be provided fast with forgery-proof surfaces.
Architecture with pattern in stainless steel sheet metal etc. made with a single-die control.
Solution:
The die is made in the nano range lathing, matrix erosion or laser ablation.
An alternative method is the manufacture of a master die in pixel size, which is then used for eroding the working die. Mono-crystalline diamonds are advantageous because of their microstructure. The brilliance is particularly advantageous.
Physics basics:
Visible light is in the nanometer (nm) range of violet of about 400 nm, blue nm, green 527 nm, yellow 589 nm, red 687 nm. These wavelengths define now the geometric dimensions of the intended structure that generates a structure color, as exemplary shown in Figure 1. In the lower picture of Figure 1 an observer's eye registers that part of the light, which is reflected, as a color, which means that the distances of the gratings is responsible for the color effect. Light that is not reflected is absorbed below the grating structure and does not appear noticeable for the eye. Hence, the step grating structure illustrated in Figure 1 is responsible for the iridescent blaze of color because light with different wavelengths is reflected due to the various lattice spacings.
For the manufacture of the punches and the dies the diffraction effect is now, similar to the colors of the wings of butterflies and a peacock's feather, imitated in form of an embossing structure to be made, which creates a diffraction grating. For example, the negative structure of Figure 1 is reproduced on the die. The distance of the cross lattices determines the color. The die penetrates preferably about'/4 of its width into the surface.
The area of the inner grating absorbs the remaining color and appears somewhat velvety, i.e., the grating matrix is shiny, and the inner part is rough. The desired color is thereby reflected, but the non-preferred color is absorbed.
In the wavelength range of visible light a metal surface is permanently formed through embossing, i.e., through cold forming, cold-warm forming or warm forming under protective gas, so that the corresponding color is created through interference. Monolithic materials are preferably used for embossing because they do not have grain boundaries that are larger than the wavelength of the light spectrum of the respective color to be embossed.
Monolithic materials are, among other examples, diamonds and monolithic grown quartzes. The hardness of a diamond, however, is an advantage.
Such methods and products are, for example, known through the Australian One Ounce Silver Dollar. The Australian silver dollar is provided with a color kangaroo, see Figure 7.

Monolithic materials are preferably used for embossing because they do not have grain boundaries that are larger than the wavelength of the light spectrum of the respective color to be embossed.
Monolithic materials are, among other examples, diamonds and monolithic grown quartzes. The hardness of a diamond, however, is an advantage.
Blue diamonds are electrical semiconductors and can be cloned with master electrodes through sink erosion methods. The clone die is made as master die with a negative structure. This allows producing several working dies.
Monolithic semiconductor quartzes can be used as a clone electrode.
Quartzes as actuators are preferably used for the manufacture of the master electrodes. See catalogue from PI Physik Instruments. They can be controlled in the nanometer range. The embossing method for producing color surfaces or for producing so-called structure colors occurs without using color pigments, but through permanently forming surfaces, which is exemplary shown in Figure 1.
Figure 1 depicts in strong magnification a rip structure, which as a step grating produces with the help of incident light, illustrated through arrows, the iridescent interference colors. The punch is made of monolithic crystals and in particular through laser treatment. In a so-called "egg" containing a methane atmosphere, diamond growth occurs on a metal cylinder through methane deposition, which creates a diamond sleeve on the cylinder.
The monolithic diamond sleeve is laser treated to produce a chequered nano structure. The hard surface of the die or the roll penetrates into the surface of the other material with the structure so that it is permanently deformed.
Mono-crystals are permanently deformed under protective gas above the re-crystallization temperature. The die or its movement is controlled through quartz, so that the penetration depth does not destroy the embossing crystal.
Through the arrangement of different dies, each for a different color effect, multicolor prints can be produced, for example, as in a color matrix printer.
A die with an integrated heating and an embossing diamond soldered to the mother die is shown in Figure 2.
A press is used for macro embossing. The monolithic die consists preferably of a diamond. Pictures are created through arranging the embossing diamonds in a manner known as Tiffany art.
The dies are used with elastic intermediate shafts to limit the pressing force.
Figure 4 shows a system for keeping the press or embossing force constant, having an embossing area 1, a solder support 2, a diamond carrier 3, a seal 4, a die carrier 5, a diamond 6, a reservoir 7, a check 8, a pump 9 and an oil cushion 10. During forming mono crystals in the nanometer range embossing is done at about 800 °C in the semi-warm range above the re-crystallization temperature under protective gas. The crystal lattice thereby remains permanently in the desired form.
With certain metals, for example, gold or copper with their own base colors, the base color is, contrary to silver or stainless steels, compensated through a phase shift of the wavelength and the interference resulting from that.
The die is preheated so that the surface of the material to be embossed is warmed so that the material is formed above the re-crystallization temperature.
For producing the die a mono crystalline diamond is laser soldered with cobalt. The phase shift of the interference lattice is adapted to the base material so that the desired color is created. For example, the star of a Euro coin is embossed in a recess to improve the forgery safety and to protect it from scratches. This is referred to as protective embossing. Preferably, the recess is configured so that the smallest coin of a currency, in the present example the 1 Cent coin, cannot enter the recess because this is prevented by a protective shoulder as shown in Figures 5 and 6.
To produce the dies micro positioning tables, for example, available from the firm PI, are used. These tables include piezo quartzes that are operable at a frequency of about 3000 Hz, and can therefore adjusted rapidly. This results in reduced processing times.
The dies are electro-statically micro coated with nano particles of colloidal Teflon to provide for cleaning and lubrication. The final cleaning occurs in an ultrasound bath with water. For producing the master structure a genuine butterfly wing or a peacock's feather (Vanessa lo) comprising structure colors are scanned, enlarged by the penetration depths of the plastic deformation, and ablated through a laser or electron ablation.
Preferably, the animals are only sedated and as such do not need to be killed.
The ablation of the surface structure occurs through magnetic ablation with sanding micro particles in an interferent magnetic field. The frequency determines the distance of the interferometer grating and, hence, the color of the generated wavelength. The scanning of the wing may be done using aura photography in the nanometer range. The light source is in the radio logic spectrum with a wavelength of about 2 nm. X-ray photography occurs with 5000 film. The treatment occurs in a vacuum tube through an electron beam grating. Material to be ablated is evaporated due to evaporation of material.
The embossing plate is polished atomically. The reflection grating has a lattice constant d = B'B, which is determined prior to the embossing. See also Figure 3.
With Euro coins, the star or the stars are embossed in a recess to provide for the forgery safety and to reduce scratching, as shown in Figures 5 and 6.
The recess is further used to center the die. The die is provided with a predetermined angle parameter. The angle parameter is for observing the color at a defined observation angle of, for example, 45 degrees with regard to the perpendicular of the crest in two planes. This is illustrated in Figure 3.
To create the multicolor embossing with such an angle parameter through several embossing steps makes the embossing process complicated and, hence, very forgery proof. In an advantageous embodiment, the angle parameter may be combined with embossing a hologram to improve the resistance against forgery. The angle parameter together with a corresponding test equipment 11 automatically helps, for example, in a state central bank, in a counting apparatus to verify if the coins are genuine, which is controlled by a spectral camera and angle coding.
With the interference Bragg condition, the step of the Echelette grating is met.
Purer color reflections are thereby created with the conditions of the Echelette grating being met. The mentioned method provides, if applied, for the coins' resistance against forgery.
Perforated foils may be applied to a coin. A die having a nano optic structure embosses the foils to produce the structure colors on the coin. With a closing die and a forming die the inner surface is protected from scratching through a super elevation. The die is made of an electron beam polished mono crystal, for example, diamond.
Plates, in particular made of austenitic sheet metals are rolled and then color embossed. The surface of the die is polished and treated through an electron or X ray drilling system. This so-called cluster sputtering is shown in Figures 8 and 9. Before that the parameters are in a CAD/CAM association determined and illustrated, or processed. In this matter, forgery of the Euro, in particular of higher values, is more difficult. The surfaces of the diamonds are heated. Thereby, re-formations in the crystal structure above the re-crystallization temperature of the materials are possible. The ruled lines 90+-are adjusted with respect to each other and treated through an electron beam.
The cross lattice is formed or treated using FEM during the re-formation so that the brilliance and purity are maintained. The whole color spectrum may be produced through multi color printing. The diamond is prepared with certain colors and the cut diamond is then mounted to the mother die in Tiffany style, in particular using laser soldering.
At one or multi-step embossing presses, the die is positioned image or angle synchronous through an optical recognition system via rotary driven dies.
One or more dies are treated in a cluster sputtering system with a short wave X ray laser, as shown in Figures 8 and 9. The one or more diamonds are made of SP 6 lattice. The diamonds are positioned under 45 and 90 degrees because of the lines of shearing stress. The embossing flux lines are therefore more precise.
Advantageous embodiments are set forth in Claims 1 to 10. The press mentioned in the claims is not illustrated, however, presses, for example, known from embossing coins, may be used, for example, a so-called C press.
The die is provided with an apparatus configured to maintain the pressing force constant, as shown in Figure 4. This apparatus or a force limitation protects the die from overload and destruction. The dies are manufactured through cluster sputtering laser burning, i.e., optic or magnetic lenses divide the particularly short wave X ray laser into numerous parallel aligned single beams. This allows to keep the number of translations smaller. The multiple division of the beams results in a shorter burning time and, hence, reduced costs, see Figure 8 and 9.
Monolithic semiconductor quartzes can be used as a clone electrode.
Quartzes as actuators are preferably used for the manufacture of the master electrodes. See catalogue from PI Physik Instruments. They can be controlled in the nanometer range. The embossing method for producing color surfaces or for producing so-called structure colors occurs without using color pigments, but through permanently forming surfaces, which is exemplary shown in Figure 1.
