Unique marking that represents the object of the present invention is the optimal solution to protect the product and the well-known trademark. This solution differs from the usual means of counterfeiting the ability to create unique and original character, which can be reproduced and which in the case of copying or imitation obviously recognizable as a fake.
The advantage of the proposed method is unique marking, component object of the present invention, is not only that it is amazingly simple, cheap and applicable to any type lines of industrial production, but also that it can be recognized by the end user appropriate technical means for a variety of goods sold.
Description of the INVENTION
Further characteristics and advantages of the present invention will be clear from the following detailed description with reference to the accompanying drawings showing a preferred embodiment of the invention and not limit its scope. In the drawings:
figure 1 schematically depicts the operation of mixing paint for marking; and
figure 2 shows schematically the operation of printing and reading, as well as registration marks printed on the product, which must be subjected to labelling, the E.
Figure 1 presents, as a first operation method unique marking applied in accordance with the present invention, produce a paint composed of a suitable binder A, which is mixed to microencapsulating microcaps B and/or finely ground to particles C, the diameter of which is in the range from 40 μm to 80 μm. During mixing finely crushed microparticles and/or microencapsulation droplets are randomly distributed mainly binding substance, thereby creating a difference on the background image or map D for each square centimeter, as shown in figure 2.
During the next operation of the method is unique marking in accordance with the present invention for this product is printed using concrete paint the sign area of about one square centimeter, which also includes a serial registration number, which will then be highlighted (figure 2) natural light or by means of a ray or beam E converging rays of white light, ultraviolet radiation, cold light, invisible or black radiation, gray radiation, protivostoyanie, laser radiation, zodiacal light, monochromatic radiation and polychromatic radiation, namely, radiation of various kinds, imposed what's on each other, and, through a series of suitable filter for the illumination of the background map of the entered character. Lighting printed sign fully reveals the randomness of the distribution, and the shape and size of the finely ground particles and/or microencapsulating droplets, thus creating a unique and differentiated background map. Unique read and registration data, which can be obtained from the background map, represented by color, size and position of the multiple fine particles and/or microencapsulating droplets within the entered character.
In private cases, the background map can be obtained from the format, dumarest, size, pattern, color spectrum, reflectivity, transparency, color dispersion, macrophotography, numerical data, density, brightness, and all those combinations, which can specify unique data and which can be recognized by the reader devices or additional lenses or filters.
The above read data is first subjected to filtration through a dark lens in order to neutralize and suppress any possible reflectivity resulting from distortion or disturbance patterns, and then it can be recognized by optical-digital camera F (2), having the first connection with the software and the viewfinder which is arranged to transmit the specified data to the database G data (figure 2) for subsequent comparison and authentication of previously labeled items.
Using the same process as described above, can be detected remotely using a specially designed portable device of the same data, obtained previously, and compare them in real time to confirm the authenticity of their conformity with the original matrix, called from the database registration data with alphanumeric coding.
In practice, in any case, the possible ways some of the implementation details of the proposed method, using known methods, with a view to better adapt it to the specific printing method, different materials and/or products (fabric, paper, metal, wood, glass, various plastics), which should be printed, and/or the type of equipment with which unique marking, shall be marked and identified.
For example, in the case of holographic labels that can be printed on paper, as a first step, make the paint using a transparent binder on phenolic-based and polyester sheet with a thickness of 50 μm, which may be splashed with spots of phosphorescent pigment responsive to the detection light, such as, for example, phosphates, and then finely ground by known methods. Grinding results in uneven destruction of the polyester film, resulting in the formation of microscopic particles with a diameter of approximately 80 μm, which is partially covered with spots and are incorrect from the point of view of volume, and from the point of view of the outer perimeter, so that all particles become distinguishing and unique.
At this stage of the process involves the input, recognition and registration of unique data on the product subject to the labeling. Finely crushed microparticles are applied to the specified product by mixing with the main transparent binder, suitable for printing, which provides enhanced durability and quick drying, and the possibility of applying to a image with a small sign in combination with a current registration number. Then the sign of the impact flash cool white light that fully illuminates the background bright geometric map thanks reflecting otslezhivaniy finely ground particles, partially covered with spots of fluorine, and chaotic distribution of these particles. This background map immediately recognizes the optical camera, which converts it into digital data and lane who gives them in the registration database for future comparisons on the subject of uniqueness. If necessary in the future to verify the authenticity of the product on which the proposed method, there is a sign of uniqueness, can be used portable optical-digital reading device, which is performed with the possibility of such recognition baseline data and compare these data with the previously registered.
In this case, for example, when using the offset or flexographic printing on paper or other media as a first step, make the paint with a transparent or colored main binder of various origin in accordance with the characteristics of print, which is admixed microencapsulation colored droplets to which features can be added to finely ground particles of graphite from natural coal. Pressure rolls, distributing paint, destroy colored microencapsulation droplets that are randomly distributed in a binder substance, and form colored portions of different colors and forms, with the possible addition of finely ground coal particles of graphite will be able to create data with the background map, which is unique, unique, visible to the eye and recognized using a camera. The data may be stored in digital format and processed using the CSO ensure that listed in the registration database in order to compare on the subject of authenticity in the course of future operations for remote reading. The background map can in any case be obtained from the format, dumarest, size, pattern, color spectrum, reflectivity, transparency, color dispersion, macrophotography, numeric data, density, brightness, and all those combinations can specify unique data and which can be detected using any readout device or additional lenses or filters.
Another object of the present invention presents the use of the proposed method is unique marking described above, in the normal process of letterpress printing, flat printing, gravure printing, screen printing, flexographic printing, screen printing, airbrushing, pad printing, thermal printing, namely, all those methods that can be used for the application of the mark or marks.
Offer a unique way can be done using paint, which is another object of the present invention.
In particular, the proposed paint made with organic or inorganic binders, the use of which printing is known and which may be liquid or pasty, painted or transparent, characterized by different types of resistance and drying in accordance with the type of product on which it should be applied, and the type of the used the used print, can be mixed with mineral oils, pigments, additives, alcohols, quick-drying lacquers, hydrocarbons, natural and synthetic resins, glycolide or other substance suitable for mixing, distribution of fine particulate matter and/or microencapsulating microdrops and applying them for various goods. To the above described binder substance can be added:
a) micronized microparticles, which can be obtained by known methods from carbon graphite material, holographic materials, hard rubber, inorganic oxides, paper, various plastics, natural or synthetic fibers, fluorescent, phosphorescent, luminescent, reflective and UV materials;
b) microencapsulation droplets of dye that can be obtained by known methods and which can be destroyed when exposed to normal pressure with the release and distribution of the dye in a binder substance and, consequently, on micronized microparticles that may be present.
Another object of the present invention provides for the use of this paint for unique marking of the product.
The following is an example implementation of the proposed method is unique marking, which is e limit the scope of the invention.
Below is a description of how unique marking on the label on the graphic print line.
In the first stage make paint for graphic printing, mainly containing phenolic transparent binder, in which dispersed the adulteration of micronized microparticles of phosphorite and microencapsulation colored droplets. The next step on the label with this paint print the sign area of approximately one square centimeter, then this simple sign lights led white light. Lighting printed sign reveals the randomness of the distribution of fine particulate matter and microencapsulating microdroplets, each time creating a unique and distinctive background map. Unique read and log data obtained from the background maps are defined by size, color and arrangement of the several fine particulate matter (7-10 particles per square centimeter) within the perimeter of the printed mark. Due to this, these fine particles form a unique two-dimensional code, which cannot be reproduced even in a production environment due to internal randomness inherent in the placement of the fine microparticles. At the end of this code decode the application of appropriate means of artificial vision and read the first video on the printed line using optical-digital cameras with high resolution, which converts the token, stores it in a suitable logical format and sends it to the server. At the next stage with the help of special software, the server decodes and stores these codes in the database while ensuring the possibility of their migration on physical media (CD, DVD, USB memory, hard drive, etc). Recorded data will serve for future comparison and confirm the authenticity of the product on which the label has been printed. Using the procedure described above, it will be possible to remotely detect through a specially designed portable device or an ordinary pocket PC this code previously generated and recorded in the database, and compare it in real time by sending using the integrated processing and transfer of information via satellite or via the Internet to verify the authenticity with the original matrix, called from the memory by the software and code to compare and verify the authenticity of the background data.
