Description

Anti-counterfeit outlets through the network twice

The present invention relates to a technical invention of anti-counterfeit outlets that pass through the network twice, and generates a unique anti-counterfeit outlet through the graphic passing file of the designer through the secondary network passing method. After combining with the designer's graphic files, the second time to screen out the outlets with different conditions, and finally combine the outlets in different areas into the final outlet structure to achieve a beautifully printed and anti-counterfeiting Sexual function.

In order to achieve the purpose of mass production, the general printed matter is to combine the designer's graphic files and then pass through the dots to generate dot signals suitable for printing and inking, and then print. The dots are mostly a single condition. The way of dots is presented in printed products, such as round dots, square dots, chain dots and error diffusion dots. The technical principle of its application is that when copying digital images of printed products, in order to achieve the visual effect of continuous tone adjustment, and when the ink is transferred to the printed material by the dot signal, the continuous tone image is transferred to the entire dot signal in 1 bit tiff binary format. The production process, and the method of determining the resolution of the dots is the number of grid lines per inch, which is called the line number LPI (Lines Per Inch). According to the resolving power of the human eye, the number of lines of the printed matter reaches 150LPI, it will look like a continuous adjustment effect, and if it is printed on the newspapers and newspapers with a rough surface, only 133LPI can be achieved. The effect of the image.

The above-mentioned dot printing technology generally does not have the anti-counterfeiting function. The present invention uses the second screen-passing method to make anti-counterfeiting dots, which can be followed under general printing standard conditions, such as ISO12647-2 (GRAPHIC TECHNOLOGY---PROCESS CONTROL FOR THE PRODUCTION OF HALF-TONE COLOUR SEPARATIONS, PROOF AND PRODUCTION PRINTS--PART 2: OFFSET LITHOGRAPHIC PROCESSES) standard, you can easily print beautiful and more anti-counterfeiting, It is difficult to imitate the network structure, and it is easy to produce and improve the anti-counterfeiting effect.

The present invention relates to a second anti-counterfeit network point through the network. The method is to firstly generate a unique anti-counterfeit network point through the graphic file of the designer through the second network mode. The first network point is used to define the area and define the difference After combining with the graphic files of the designer separately, do the second screen to get the dots of different conditions, and finally combine the dots of different areas into the final dot structure to form a printed product with anti-counterfeiting. The image file is placed in the same image through the two times of the network to produce different conditions of the dots, the human eye will appear to be a consistent color, and it is also very easy to identify the authenticity of the work, as long as you use a mobile phone to shoot or a low magnification magnifier , You can quickly observe whether the printed matter has secondary anti-counterfeit network points, so as to judge its authenticity, and obtain a high degree of progress.

The first figure is the flow chart of the second network crossing of the present invention

The second and third figures are schematic diagrams of embodiments of the present invention

The present invention relates to a second anti-counterfeit network outlet, please refer to the flow chart of the first figure, and its method is to first generate a unique anti-counterfeit network outlet through the second network access method, and first pass the network to a different network outlet To define the area, define a number of different areas, after the area set After the calculation, they are integrated with the graphic files respectively, and the second network crossing is performed to obtain multiple sets of network points with different conditions. Among them, the first network crossing mainly generates the region of interest, ROI (Region Of Interest). To simulate the effect of continuous tuning, the number of lines must be higher than the human eye's resolving power, and the area range used as the second time when passing the network. Therefore, there is not only one type of outlet when the first time passes the network Conditions, can also have a variety of dot conditions, or adjust the depth of the continuous adjustment image and then carry out the first screen to get the size of the basic point of the desired area; the second screen will be accepted after the first screen The different area ranges generated are combined with the continuous adjustment image again, and a second screen is passed to generate dots of different conditions; finally, the dots of different areas are combined into the final image to complete a special anti-counterfeit dot structure Exquisite brush products.

As shown in the second and third figures, it is a schematic diagram of an embodiment of the second network passing of the present invention. The second image shows that two different dots are placed in the same image, and the continuously adjusted image passes through the first network passing to generate 2 parts. The ROI area is combined with the continuous adjustment image for the second half point, which is the 250LPI round half point and the error diffusion half point, and then the two kinds of half points are combined into the final image; the third picture shows the three different half points. In the same image, after continuously adjusting the grayscale image of the continuously adjusted image, 2 parts of different dot size areas are generated through the first pass through the network, and then 3 parts of the ROI area are obtained by logical operation, different ROI areas Combining the original continuous tone image through the second dot, respectively, 250LPI circular dot, linear dot and error diffusion dot, and then combine these three dots into one image.

The method of generating anti-counterfeit dots through the second pass of the present invention puts dots of different conditions into the same image at the same time, but it can make the colors of the image look balanced and consistent under the expansion of different dots. The main principle If the number of lines passing through the network for the first time can be higher than the resolving power of the human eye, the effect of continuous tone adjustment can be expressed in the form of dots, although different areas Although there are different dots in different conditions, there are different dot expansions. However, due to the ability of the human eye to distinguish, different shades of color are actively reconciled to a consistent color, that is to say, the human eye is the best color palette. Role, so that dots of different conditions can be put into the same image, but color consistency can be easily obtained. That is to say, with the dot structure of the present invention, color consistency can be easily achieved before and after printing color management. The second pass through the network produces dots of different conditions placed in the same image, the human eye will appear to be a consistent color, and it is also quite easy for general identification work, as long as there is a mobile phone shooting or a low magnification magnifier, you can quickly judge the printed matter The authenticity of the present invention, therefore, the invention can easily print a beautiful and highly anti-counterfeit network structure that is difficult to be copied, and has excellent industrial utilization value.
