The present invention relates to a method of manufacturing a protective signs for protection of the products, and such protective signs.
The level of technology
The development and continuous improvement of a multiplier technology makes it increasingly easy copying of documents or forgery, namely, paper money, Bank notes, stamp papers, and other similar documents and securities.
Authentication of the product is to verify the identity of the items marked on the product. These identification elements are usually included in the product marks or security features that can only be read by the detector. The check consists in comparing the nature, form and location identification of the elements with identifying the elements entered in the memory device, which verifies, without access to them and/or their violation. This situation is true in regard to items such as Bank notes. Such products have included themselves in tickets protective and control elements, usually read by means of light radiation with a certain wavelength, preferably in the invisible region of the spectrum.
However, the improvement of analysis tools available on the market, makes it all the more zatrudnitel the th implementation of effective countermeasures, i.e. methods that do not allow to detect and to analyze protective and identifying elements not authorized persons and, therefore, to use this knowledge to counterfeit products by enabling the identification of elements that, when read by the detector will be interpreted them as genuine identification elements.
In the field of identity protection it is possible to develop tools, complicating fake object or product or at least make such falsification is difficult to ensure that it was in their economic interest.
However, the situation for products manufactured or used in very large quantities, as, for example, with Bank tickets or armorial securities, the cost of manufacture and which, in particular, the cost of their protection should be limited. In other words, for these products, remedy or protect against fraud should be included in the industrial process and must be compatible with the conditions of their industrial production. The cost of their production should be acceptable.
So, currently when printing Bank notes, paper money, stamp securities and other similar securities using the classical technique of printing in which limited the accuracy limits is Catania and location identification elements.
Introduction identification of elements in the form of holograms gives spots in the same physical limits of error and therefore does not generate the necessary protection.
The objective of the invention
The present invention was based on the objective to develop a method that would allow to significantly increase the degree of protection of products from possible tampering.
Description of the invention and its main advantages
According to the invention this problem is solved using the method of manufacturing a protective marks on the media having a first surface and a second surface opposite to the specified first surface, namely, that
the first surface of the carrier seal with high resolution varnish
the carrier was processed using electrolysis,
the carrier is washed and dried.
By printing with high resolution is achieved with a high accuracy and location of protective signs. Genuine product, i.e. a product having the identification mark can be recognized with increasing protective signs by several orders of magnitude.
Protective character is used in this state or may be transferred to the surface and/or inside of the material for convenience and authentication.
The accuracy of the sign also allows you to increase the complexity of the shape, i.e. the contour of the inclusions or resists (protective layers) or even more complex placement of the identification elements, and, in addition, this embodiment of the sign allows you to enter identifying elements that can be detected or perceptible only under the conditions corresponding to the precision of the token.
Before printing on the medium, it is preferable to apply the coating on the first surface. This coating preferably is a metal or metal oxide or oxides, salt or salts of metals or metalloids, or their mixture.
Between the coating and varnish can be located intermediate separation layer and/or relief of the intermediate layer. This last layer facilitates the creation of micro-relief printing. The intermediate layers consist of a protecting layer for a protective sign and give to him, for example, abrasion resistance.
The intermediate layer can maintain good adhesion of the other intermediate layer in conditions of transparency, which does not affect the final appearance of a token.
The intermediate layer mainly contains optical fragments with different diffraction and/or hologram.
Printing with a high resolution is carried out preferably by means of electrically insulating varnish.
Varnish is primarily a polymer, preferably a cellulose type, and/or metal type and/or plastic-type and/or plastic t the PA coated, deposited by vacuum metallization.
The polymer, for example, is a mixture of nitrocellulose resins, preferably of nitrospira, supplemented resins, improves resistance to subsequent processing of lacquer, for example, gum Arabic, and rosin. The polymers can also be a mixture of resins, supplemented by one or more adhesion promoters, preferably butylacetoacetate.
In another embodiment, the varnish is insoluble and is a nitrocellulose polymer containing filler, the nature of which varies depending on the subsequent functions of the mark, in particular the use of pigments or conductive or insulating fillers such as metal oxides, preferably titanium oxide, iron, boron, Nickel, chromium, carbon, silicon oxide, pure or in a mixture. The lacquer is advisable to carry out by any means for printing capable of varnish with high accuracy and high resolution.
In accordance with a preferred embodiment of the invention the lacquer carried out by means of printing gravure printing.
Gravure printing allows printing with high resolution without jagged edges. Thus, the printing precision unexpectedly improves the accuracy detective who work in the opposite so far, when reducing the size of the identification elements of this accuracy was severely limited because of the risk of errors associated with printing in the production. Such precision makes it easier to disguise the set of identification elements are not distinguishable in terms of traditional analysis. Finally, this greater accuracy allows to increase the number of elements of the sign and the result is to increase the protection against fraud.
The varnish applied on a basis appropriate to handle such a way as to modify the picture, or adding material or ablation. Add material can be carried out using any of the printing means, preferably by means of a jet of paint under pressure. Ablation can be performed using any destructive means, preferably representing gravioli the laser beam which passes through a screen having a window, or brush, is directed to submit a letter or graphic image, which can be varied without contact with the metal film. Thus you can enter in Lac permanent and/or changing fragments, such as numbering, indexing, personal symbols, etc.
In accordance with another preferred embodiment of the invention Nanase is their varnish perform a method of digital printing. In this way it is possible to perform printing with paint or coatings, for example, a jet printing ink under pressure through a liquid, solid or dry rendering, ecografia in contact with a layer of Foundation or without him. The use of digital printing can produce small series and perform partially distinguished figures, such as numbering. In addition, digital printing eliminates some of the drawbacks printing method, gravure printing, for example the manufacture of expensive printing plates requiring sometimes too long periods of time. Therefore, digital printing is simpler, faster and less expensive way than the printing method of gravure printing, while maintaining high resolution.
In accordance with the embodiment of the invention the lacquer preferably contains a filler. This filler may, for example, to have a marker in the form of beads, which are preferably smaller than 1 μm. Being so small, the beads are indistinguishable to the naked eye, but they can be detected by the microscope in a narrow band of the transmitted light, as fluoresce when illuminated with UV-light.
It is advisable to include in the beads stable trace elements, such as the DNA chain. Such molecules preferably are coated in view of the protective polymer.
When using these DNA chains get invisible to the naked eye marker with more than 1018possible individual codes.

Before deleting (figd) of the outer layer of glue 24 the final substrate 26 are glued to the nail 20 (high to expose the floor.
Figure 5 shows the installation for implementing the method described above. This installation consists of a node of the power that is supplied from the main warehouse BA1 film wound on a bobbin. On site supply reel to unwind the supply node of printing In; then the output from this node printing strip BA2 sent to the node With electrolysis, in which physico-chemical treatment in the Windows film vases. For the node With the electrolysis unit is flush D, which remove water-soluble varnish, getting the film A, and washed stripes is. Then the band WE sent to the node drying E and, finally, of the control unit F in winding the node G.
The feeding Assembly And consists of tape drives A1 with the coil A2. The tape drive device is driven by a motor associated feedback with a group of rods A3, which provides for a controlled tension in the band BA1. Then the strip is sent to the host printing, which in this example is a host printing method of gravure printing, consisting of a block of gravure printing (6 and 7) with colourful apparatus B1, the gravure cylinder B2, immersed in the inking unit B1 to completely cover the surface of the covering cell gravure printing and the outline of the window. This cylinder works together with squeegee B3, which removes from the surface of the paint, which remains only inside the hundred or picture. Paint B1 is supplied from the tank B4 containing the coating material, with a pump B5 and pipe B6. The tank B4 equipped with a device for determining the viscosity B6, such as viscometer to adjust the viscosity of the liquid coating.
Block gravure printing can be equipped with a system of reading spots or detected token using a photovoltaic cell that is metallized strip that allows you to control the strip so that the location of the Windows printing was combined with p is sungami on metallic strip, in some cases containing the pre-printed signs.
The liquid level in the ink unit B1 is controlled by overflow pipe V7 with return to tank B4 so that the plate cylinder gravure B2 was always immersed to the same depth in the inking unit B1.
The cylinder B2 works together with the pressure cylinder 10, is placed over the lane BA1; cylinder B2 is under the line.
Band BA1, as is schematically presented in figure 1, consists of a carrier 10 from a plastic material and the primary coating 14, for example made of metal.
When rotating in the direction of the arrows cylinder gravure B2, interacting with the pressure cylinder 10, is pressed against the strip BA1 and causes the varnish according to Windows in the form of printed areas or coatings 1.
Figure 7 presents a top view of the printhead shown in Fig.6. 7 in a top view is shown of the plate cylinder gravure B2, the pressure cylinder 10 with an arrow pointing to the direction of pressure, and the band VA. The cylinder B2, having an engraved surface in accordance with the window gravure printing or the printing area B21 relatively complex shape, causes the imprint 1 varnish to cover the basics of 14 bands BA1 (which then becomes the band BA2).
On Fig-11 shows in more detail the execution by etching the surface of the window is gravure printing.
On Fig shows the desired contour of the window, gravure printing, i.e. the contour of the future sign (I100).
On the basis of this form I100, engrave the surface of the window gravure printing cylinder. This window represents the engraved surface, consisting of separated walls C recesses or cells C, surrounded by a rim C, which is bordering the cavities and the spaces between them.
In this drawing, the cells are represented by black squares with rounded corners, in some cases, truncated, split white walls (partitions, also called bridges) C.
The combination of the cells or recesses surrounded by the rim, i.e. a very narrow groove, which is filled with paint, but does not allow it to spread outside of the cells, due to what obtained printed image having a continuous loop, accurately and clearly limiting predefined window border.
Figure 9 bezel C passes through the cavities or near them.
Figure 10 box I200 also has a cell C separated by partitions C, which are also surrounded by a bezel C, which is more removed from the edge of the cell C (truncated or non-truncated)than in the embodiment of Fig.9.
The clarity of the linear component of the rim depends on the resolution of the picture, which is depicted in the box or boxes; thus, the choice between forms of engraving on figures 9 and 10 depends on the viscosity is hidcote, used for printing. As indicated, the liquid in the dry state is a product of passivation, i.e. inert to carry out physico-chemical effect.
Finally, figure 11 shows the fingerprint image I300 with a very clear path without teeth.
Returning to figure 5, the node EW has an electrolytic bath S1, which is in contact with the strip BA2, on which the node was already dealt imprint. This site electrolysis also has a hood C2 for exhaust gases of electrolysis. The details of the node C2 is represented on Fig, 13, 14.
On Fig shows schematically the site electrolysis With alternating electrolytic baths C3, C4, C5, C6, United pipelines 7 and the feed pump C8 with the electrolyte reservoir C9. Band BA2, with a floor I, touches the surface of the liquid contained in the electrolytic baths C3-C6. In each of these baths are electrodes C10, C11, C12, C13 with opposite polarity, and the electrolysis is carried out from one bath to another.
At the exit there is a bunker manifold 15 into which a liquid dripping from the strip BA3, which is compressed when passing between the two cylinders C16, C17. Wrung liquid is collected in the hopper 15, whence it returns to the capacitance C9.
On Fig shows a top view of site electrolysis C1, cast the STI, with partitions C20, C21, C22, sharing baths. This drawing also shows the connection of the positive and negative electrodes with a common busbar collector C30, C31.
On Fig presents in perspective an embodiment of a node electrolysis C1 using the same signs that were mentioned above, and therefore their description is not given.
The conditions under which conduct the electrolysis depend on the nature of the metal subjected to electrolysis. The electrodes are non-consumable electrodes, which are simply remove the coating film in places not protected pestiviruses layer, i.e. outside the contour of the window.
Another option, when the purpose of electrolysis is the application or removal and application of metallized layer, as has been mentioned earlier.
Finally, the operations of printing and electrolysis can be repeated with various forms of Windows, made one on another, for example, for formation of the integrated circuit; and in this case would be to alternate the sequence of nodes In, With, and in some cases D.
Next film BA3 sent to the node washing D. In this node washing lane BA3 washed to remove residual electrolyte and dissolution of the coating layer, in particular pestiviruses layer. This site washing D contains various cylinders D1, D2, feed strip BA3 first tub D4, and satemwa second tub D5. These baths contain a liquid for washing of the electrolyte and/or a solvent and coating. Detailed design of these washing baths is not given. We are talking about a set of cylinders, determining the direction of circulation of the strip in the wash tub.
Rinsing is carried out with drying between the steel cylinder and a polymeric cylinders to limit entrainment and facilitate drying by evaporation of the washing liquid, so that the film was dry and without traces of electrolyte is not compatible with its future use.
After node D wash lane WE sent to the node drying E, equipped with ventilation and air removal, E1, E2, E3, E4, and, finally, the dry strip WE served in the monitoring unit F, equipped with a video camera F1, which scans a zone film V for quality control of production. This monitoring is supplemented by measurement of optical density and specific resistance (not shown). Control is carried out continuously. The output of the control unit F the film is wound in the host wound G. the Node winding G has a structure similar to the structure of the unwinding site, but operating in the opposite direction. It includes the holder G1, is supplied by a motor, and the bearing cylinder G2.
After the host control strip strip is inserted into the machine and is wound under controlled tension to the e was deformed in the areas of thickening.
The regulation of the passage of the strip through the installation according to figure 5 is sinhronizovano using frames and readout devices, and control circuits. These devices are not shown.
The installation has the advantage in terms of speed of processing, allowing you to exceed the processing speed of 250 m/min Processing is not sensitive to the presence of metal oxides, which protects the metallized surface of the film, which is a significant advantage compared with the known chemical methods. The possibility of applying a metal layer of a different nature than that which was subjected to corrosion, allows to obtain a multilayer metallized product.
The resolution of the resulting metallized hatch is the same as the printing resolution, since the thickness of the corrosion layer masking can be 2 microns or less.
Finally, it should be noted that the printing of treatment must be performed resist can be carried out on a separate machine, regardless of the machine for processing.
To determine the nature of the DNA code contained in the beads, conduct a comparison of the codes registered in the data Bank, looking for similar, which will clarify the origin of the product.
Using an eye for counting threads or lenses, which gives a 12-fold increase, the beads become visible and with appropriate lighting.
Sampling of several fragments of varnish, approximately 10 beads is sufficient for laboratory analysis to compare after purification and concentration on the column and the membrane of the DNA code sample code reference DNA data Bank to determine the code sample and set user code corresponding to the code sample, using an amplifier in DNA.
After 40 thermal cycles (30-90° (C) investigate the hybridization of the sample DNA with its counterpart from the data Bank. Two adjacent curves show an example of hybridization (figa) and the absence of hybridization (figb) respectively between DNA samples and DNA from the database.
In the analysis of (A) DNA samples has found his double and code DNA samples match the code of the DNA from the database.
