I. paper anti-counterfeiting

paper is the material basis for printing all kinds of securities. Some special papers made by special processes basically have anti-counterfeiting characteristics. The anti-counterfeiting technologies used in special papers mainly include:

1. Watermark paper

watermark paper can use technical means to put the required marks, patterns, etc. into the paper during the manufacturing process, These patterns are not easy to see under normal circumstances, and can only be seen against strong light. They are recognized by anti-counterfeiting experts all over the world as an effective anti-counterfeiting technology. Banknotes, important international documents, facility drawings and various tickets of most countries are also printed on water printing paper. Besides being used in currency paper, watermark has also been widely used in other ticket paper. There are fixed, unfixed and semi fixed positions of watermarks in the paper. In the manufacturing process, it integrates complex technological processes such as design, mold carving, paper making, and so on, so it often makes counterfeiters helpless. Checking the watermark is also one of the most effective means to identify the true and false

2. Safety line

safety line refers to placing a gold line or plastic line in the middle of the paper in the process of papermaking. The first safety wire used was special gold wire. Now it is plastic wire and has developed into a variety, such as miniature letter safety wire, fluorescent safety wire and so on. The shape of the safety line includes straight line, wavy shape, sawtooth shape, etc

3. red and blue fibers or color dots

in the process of papermaking, red and blue fibers or color chips (dots) are mixed into another pulp, or scattered on the surface of the paper before the paper is unshaped, and there is fluorescence reflection under ultraviolet radiation. There are two kinds of fixed position and unfixed position of red and blue fibers and colored dots in the paper

4. Copy proof paper

after copying, the words "copy and invalid" will appear on this paper, which can effectively prevent color copying of important documents. Another kind of full absorption copy proof paper is blue or brownish red in appearance. The pictures and texts on the paper can be seen only through light, and its copy is dark

5. Non fluorescent special paper

general paper shows fluorescence under UV irradiation. Therefore, non fluorescent special paper is used to prevent counterfeiting of banknote printing paper and some securities or bills. For example, the paper bases of banknotes, passports and some tickets in various countries have no fluorescence, which makes it easier to show fluorescent pictures and texts with additional secret marks

II. Album printing technology

for example, multi-color cross printing, also known as cross color printing or rainbow printing, is generally printed by relief printing machine. It is based on the requirements of printing materials, after placing a partition in the ink tank, and then putting a variety of color inks in different partitions. Under the action of the inking roller, the ink of adjacent parts is mixed and then transmitted to the printing 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 placement distance of the ink tank partition from the print, it can also play a certain anti-counterfeiting role. If this process is used in large-area shading printing, its anti-counterfeiting effect will be more prominent

III. anti counterfeiting ink

1. UV fluorescent ink

special ink that can emit visible light under UV irradiation

2. Color changing anti-counterfeiting ink excited by sunlight

anti counterfeiting printing ink that can emit visible light under sunlight. The color changing effect can change from colorless to purple, blue, yellow and other colors, and can also be designed to change from colored to colorless

3. Thermal anti-counterfeiting ink (also known as thermochromic anti-counterfeiting ink)

ink that can change color under the action of heating. According to the temperature required for color change, it can be divided into hand temperature color change anti-counterfeiting ink and high temperature color change anti-counterfeiting ink. According to the difference of color changing ways, it can be divided into single color changing reversible, multi color changing irreversible and multi color changing irreversible thermosensitive anti-counterfeiting inks

4. reactive color changing ink

various chemical substances added to the ink can produce various chemical reactions under certain conditions, so as to change the color of the ink and achieve the purpose of anti-counterfeiting. As a part of heat sensitive anti-counterfeiting ink, pressure-sensitive color changing ink and humidity sensitive color changing ink belong to color changing ink

5. Magnetic ink

is a special ink made by mixing magnetic iron oxide powder into the ink. At present, it is mainly used to print magnetic coded words and symbols of bank tickets, with the effect of recording and storing information. Put the ticket printed with magnetic code into the magnetic code reader to identify the authenticity

6. Except for the correction ink

if the correction is made in the corresponding part, it is expected that some password will appear when the starting conditions are available in August. This ink is mainly used to print checks, bills of exchange, documents and other securities. If someone alters or erases the original number on the face value of the bill, the word "void" will appear immediately

IV. bar code anti-counterfeiting technology

commodity bar code is a kind of code of commodities, which is designed by human beings for the effective management of commodities such as computers. If we can reasonably use commodity technology, including reasonably selecting the carrier of bar code, reasonably selecting the printing method and printing machine, reasonably selecting the printing position, etc., it is possible to make commodity bar code technology have anti-counterfeiting effect

due to the greater amount of information, the two-dimensional bar code has strong anti-counterfeiting through the processing of computers and inkjet printers. There is also the application of calibration ma. Through a formula operation, a continuous number followed by a specific number can also play an anti-counterfeiting role

v. code anti-counterfeiting identification and identification system

code anti-counterfeiting identification and identification system is to set a random password on each product, archive all records of all incoming products in the anti-counterfeiting data center library, and let consumers use, computers and other tools to check that we all know that it will be troublesome to identify the authenticity of products when installing large-scale equipment, whether the password is correct or not. This anti-counterfeiting technology is implemented on the same physical object to achieve the purpose of high anti-counterfeiting

VI. pattern design anti counterfeiting

pattern design, also known as flower ball design, twisted rope decoration design, shading background design

this is one of the oldest and oldest anti-counterfeiting technologies. You can see this kind of background picture and text on the familiar banknotes, passports and cheques

the current safety graphic design system is combined with computer technology, which can be designed according to the user's own style, and design a complete graphic background and Related words with distinctive personalized characteristics, such as flower ball, microfilm, microfilm, anti scanning graphics, anti copy graphics, relief graphics, etc. These pictures and texts adopt line design and spot color printing, which can effectively prevent color separation printing and color copying after being copied by traditional means such as electric separation and photography, and play an obvious anti-counterfeiting role. This is exactly what criminals driven by huge profits don't like, so this kind of safe graphic design is still widely used in the production of banknotes, cheques, important national certificates, securities, etc
