Application of Anti-counterfeiting Technology on Picture Printing

First, paper security paper is the material basis for printing a variety of securities, some special paper manufactured using special processes basically has the security features, and the anti-counterfeiting technologies used in the analysis of the special paper in the Ame Mall are:

1. Watermark paper watermark paper During the manufacturing process, the required logos and patterns can be incorporated into the paper using technical means. These patterns are not easy to see under normal circumstances, and can only be seen against strong light and are protected against all countries in the world. Experts generally believe that it is an effective anti-counterfeiting technology. Most countries’ banknotes, important international documents, facilities drawings and various kinds of tickets are also printed on watermarked paper. In addition to being used in currency paper, watermarks have also been widely used in other ticket papers. The position of the watermark in the paper is fixed, not fixed and semi-fixed. In the manufacturing process, it integrates complicated processes such as design, engraving, web-making, and papermaking, and therefore often makes counterfeiters useless. Checking the watermark is also one of the most effective means to identify true and false.

2. Safety Line Safety Line means that a gold or plastic thread is placed in the middle of the paper during the papermaking process. The earliest use of the security line was special gold wire. Now plastic wire has been used and it has been developed into various kinds, such as miniature letter security wire and fluorescent security wire. The shape of its safety line is straight, wavy, zigzag and so on.

3. Red-blue filaments or colored dots Red-blue fibers or colored flakes (dots) are incorporated into pulp during the papermaking process, or sprinkled on the surface of the paper before the paper is unshaped, and are fluorescently reflected under ultraviolet radiation. The red and blue fiber yarns and the color dots have a fixed position and a non-fixed position in the paper.

4. Anti-copying paper After copying the paper, the words “copy” and “invalid” will appear, which can effectively prevent color from copying important documents. Another type of full-absorption copy-proof paper has a blue or brown-red appearance. Only the light on the paper can be seen through the light, and the copy is dark.

5. Non-fluorescent special paper General paper is fluorescent under UV irradiation. As a result, banknote printing paper and some valuable securities or notes are printed using special paper without fluorescence. For example, the paper bases of the national banknotes, passports, and some tickets are not fluorescent, so it is easier to reveal additional fluorescent graphics.

Second, the album printing technology, such as multi-color string printing, multi-color string printing, also known as cross-color printing or Rainbow printing, generally more use of letterpress printing, it is based on the requirements of the printing product, after placing the partition in the ink tank, and then in Different shades of ink are placed in multiple shades. Under the string action of the skein roller, the adjacent ink is mixed and transmitted to the plate. With this printing process, multiple colors can be printed at one time and the middle transition is soft. Since it is difficult to see the distance of the ink tank partition from the print, it can also play a certain anti-counterfeiting effect. If such a process is applied to large-area shading printing, its anti-counterfeiting effect will be more prominent.
Third, anti-counterfeiting ink 1. UV fluorescent ink under ultraviolet light, can emit special light visible light.

2. Sunlight-activated color-changing anti-counterfeiting ink In the sunlight, it can emit visible-light anti-counterfeiting printing ink. The color change effect can be changed from colorless to purple, blue, yellow, etc. It can also be designed to change from colored to colorless.

3. Thermal anti-counterfeit ink (also known as thermochromic anti-counterfeiting ink) can be discolored when heated. According to the different temperature required for discoloration, can be divided into hand-temperature color anti-counterfeiting ink and high-temperature anti-counterfeiting ink. According to the difference in color change, it can be divided into single color reversible, multi-color irreversible and multi-color irreversible thermal ink.

4. Reaction color-changing ink Various chemical substances added in the ink, under certain conditions, can produce various chemical reactions, so that the ink changes color, to achieve anti-counterfeiting purposes. Part of the heat-sensitive anti-counterfeit inks, pressure-sensitive color-changing inks, and humidity-sensitive color changes are all color-changing inks.

5.Magnetic ink is a special ink made by mixing magnetic iron oxide powder into ink. At this stage, it is mainly used to print magnetically encoded letters and symbols of bank tickets, which has the effect of recording and storing information. A magnetically encoded ticket can be inserted into a magnetic code reader to identify authenticity.

6. In addition to altering the ink, if a correction is made in the corresponding part, a password will appear. This kind of ink is mainly used to print securities such as checks, bills of exchange and documents. If someone changes or eliminates the original number on the denomination of a bill of exchange, it will immediately appear as "Voided."

Fourth, bar code anti-counterfeiting technology Product bar code is a kind of product code, which is designed for the effective management of computer and other commodities. If we can reasonably use commodity technologies, including reasonable selection of the carrier of the barcode, a reasonable choice of printing methods and printing machines, a reasonable choice of the location of printing, etc., then it is possible to make the commodity barcode technology have an anti-counterfeiting effect. Due to the greater amount of information, 2D barcodes are highly resistant to counterfeit by computer and inkjet printers. There is also the application of checkma, which can also be used for anti-counterfeiting through a formula operation, followed by a specific number after a consecutive number.

V. Code anti-counterfeit identification and telephone identification system The code anti-counterfeiting identification and telephone identification system is to set up a random password on each product to archive all the records of all network access products in the anti-counterfeit data center library, allowing consumers to use telephones, computers, etc. The tool verifies the correctness of the password to identify the authenticity of the product. This anti-counterfeiting technology is implemented on the same physical object to achieve a high degree of anti-counterfeiting.

Sixth, pattern design Anti-counterfeit print design, also known as flower ball design, guilloche ornaments design, shading background design. This is one of the oldest and oldest anti-counterfeiting technologies. This background image can be seen on familiar banknotes, passports, and cheques. The current security graphic design system is combined with computer technology, and can be designed according to the user's own style. The complete pattern background and related texts with distinctive personal characteristics are designed, such as flower balls, miniatures, miniatures, and anti-scanning drawings. Text, anti-copying graphics, embossed patterns, etc. These graphics and texts are designed with lines and spot colors, which can effectively prevent the separation of electricity, photography, and other traditional means of color separation and color reproduction after copying and play a significant anti-counterfeiting effect. This is exactly what the criminals are driven by the spurious profits, so this security graphic design is still widely used in the production of banknotes, cheques, national important documents, securities, etc.
