The invention of printing is a symbol of human civilization. Printing is an accurate, rapid, large-scale, economical reproduction of graphic and textual information that is widely distributed and permanently stored on various substrates. It embodies a kind of ideological, serious, time and artistic characteristics. It is inextricably linked with people's daily life. The dissemination of education culture and the exchange of new scientific and technological knowledge are all based on print. People today can't live without print. In recent years, due to the development of science and technology, the application of new technologies, such as computer plate making, digital printing, and laser, has greatly changed the traditional printing methods and expanded the field of printing. The printing of tickets (vouchers) is a special way.
The printing of tickets (vouchers) can be said to be one of the most closely related to people's daily lives. From commonly used banknotes, bonds, industrial and commercial tax invoices, stocks, cheques, securities, stamps, and even cars, boats, and air tickets, etc. Tickets (vouchers) are related, which is related to individual's rights and interests. For example: If you hold any kind of fake tickets (vouchers), you will damage your own N equity, and even more serious will involve related legal issues. Therefore, ticket (vouchers) printing is not only a professional printing technology, but also a security printing service. It has specific requirements and processes, as well as relevant professional knowledge and technologies, especially in the use of various special technologies. The technique is quite different from general printing. However, this kind of printing is often thought to refer only to the printing of banknotes. Actually, the cheques, shopping invoices, stamps, and stocks that we came into contact with in daily life are all printed on the ticket. In today's rapid economic development, the amount of tickets held and used is greater. Therefore, users who hold and use tickets (vouchers) must not only have the ability to distinguish between genuine and fake, but also have a ticket (vouchers). ) The printing technology should be improved, and the printing process needs to have a deeper understanding. For example, the paper, ink, and printing methods of the printed ticket can be used to determine its authenticity. First, the definition of the value of tickets (vouchers) Definition: The so-called tickets (vouchers) are on the special anti-counterfeit paper (such as watermark paper), after the printing of special characters, patterns and lines, and the formation of Value, printed on a denomination, this type of print can pass through the market, can represent tradable value, legal ownership and officially officially recognized qualifications. Second, security printing ticket (vouchers) application of the field 1. Bank issued tickets (vouchers):
Banknotes, checks, withdrawals, deposits, coupons, passbooks, etc. 2. Government issued tickets (vouchers):
Bonds, invoices, tax receipts, welfare lottery tickets, certificate certificates, etc. 3. Posts issued by the post office (vouchers):
Stamps, money orders, stamps, postcards, etc. 4. Other tickets (vouchers):
Shopping tickets, corporate securities, stocks, cars, boats, tickets, ticket vouchers, etc. III. Disadvantages of Valuable Tickets (Vouchers) The biggest disadvantage of coupons (vouchers) is the forgery and alteration of some criminal elements. Especially in the era of advanced technology, various new types of copiers and laser printers. With the advent of electronic scanning color separation machines, computer plotters, etc., counterfeit goods have reached a point where they are really confused. For example, on April 6, 1999, during the inspection of large-scale invoices conducted across the country, the issue of invoices was found to be quite serious. Criminals using false invoices, false taxes, tax evasion and fraud, and corruption and bribery would be illegal. Activities, embezzlement and fraudulent national property seriously disrupted the economic order. It is worthwhile to point out that even anti-counterfeiting technology itself has been counterfeited, causing greater confusion to the law enforcement agencies. Therefore, how to prevent counterfeiting or copying is a major issue in the printing and use of tickets (vouchers). This topic is to use the scientific method in the protection, anti-counterfeiting, recognition, and use of valuable tickets (vouchers) in order to determine their authenticity. IV. Principles to be followed in the printing and use of valuable tickets (vouchers) 1. Printing and ordering must entrust professional companies with safety management.
2. When designing a ticket (voucher) pattern, a complex pattern (color gradient, miniature text, embossing effect, manual text encryption, etc.) should be used, and the original regular pattern should be changed to a random pattern to prevent copying.
3. 1 The special security and anti-counterfeiting papers (watermarked papers, patterns can be customized as required) or dry carbon paper should be selected.
2 The raw materials should fully reflect its physical properties (bronzing, concave and convex surface treatment), chemical properties (colorless ink, fluorescent ink, photochromism, transparency, temperature change, magnetic ink, etc.).
4. Codes should use magnetic codes and special numbering machines (fonts can be selected).
5. Time Limit (Lifetime): Any anti-counterfeiting has a time limit, and it must not be changed in order to avoid imitation.
6. Ease of identification: Although any security ticket (voucher) has been produced with tighter anti-counterfeiting measures, it is more necessary for users to easily identify it.
7. Establish a rigorous protection concept: All processes should be treated with the same care as banknotes in order to prevent problems. V. Identification of genuine and false tickets (vouchers) When we hold a valuable print, such as cheques, certificates, banknotes, invoices, etc., once they are identified as counterfeit goods, the rights of the holders are immediately damaged. . Therefore, it is necessary to have some knowledge of identifying the authenticity of tickets (vouchers) so that timely measures can be taken to safeguard their rights and interests.
(I) Identification of paper Paper is mainly composed of plant fibers and auxiliary materials, plus special treatment. Its main physical properties are: durability, tear resistance, flex resistance, smooth surface, easy writing, and a sense of value. Therefore, we can recognize from the following aspects:
1. Anti-counterfeit paper has no depth of watermark or watermark. Illumination of light or comparison of two identical tickets (vouchers) can be used to identify frauds.
2. The color and position of the dark line. General paper does not have to be placed in the dark line. Only special papers with special value (vouchers) are available. There are many different colors of dark lines. There is a single color or a mixture of colors in the production. If the position and color match, it is genuine. Of course, sometimes slight differences are not counterfeits, but errors in production.
3. The structure of special filaments. According to the characteristics of different documents (vouchers), the production of different fiber filaments and their distribution are also different, sometimes colored visible fiber filaments, but also invisible fiber filaments. Both are under ultraviolet light, which can be reflected by fluorescence, have different color vision and special structure, these are the key points of identification.
4. The thickness and evenness of the paper. The thickness and evenness of paper can be seen through light or light to see if the distribution is even and can be identified by hand.
(B) The identification of ink Ink identification is a more professional approach, most people can not easily identify.
Ink is a combination of pigments and some additives. It can be distinguished from the following methods:
1. Color color: Carefully observe the color of the printed matter is correct and bright, and has a glossy.
2. Texture: Letterpress and gravure prints often have strong texture and bright colors. You can use your hands to directly touch the surface with convex and concave feelings. Plain printing shows the pattern is more even and the pattern is lighter.
3. Water resistance: According to the different printing products, you can choose water-resistant ink, if any, the price certificate (vouchers) to prevent water, alcohol and other liquids to change the ticket surface, the use of water-soluble ink, making it difficult to achieve the purpose.
4. Lightfastness: After a period of intense UV and sunlight exposure, poor inks often fade.
5. Abrasion resistance: According to the different printing products, some often use ink with strong abrasion resistance to prevent alteration.
6. Special ink:
1 Fluorescent ink: This ink is fluorescent under ultraviolet light irradiation. Divided into colored and colorless fluorescent inks.
2 photo-induced variable ink: The characteristics of this ink is colorless, easy to distinguish authenticity, imitation is difficult. Identify only in two seconds under the violet light or in the sunlight.
(3) Different ways of identifying the printing methods Printing methods also show different characteristics. These characteristics also bring favorable conditions for identification. The following briefly describes the characteristics of several commonly used printing methods:
1. Lithography: is a commonly used indirect printing method, characterized by the average imprint, imprinted around the same, ink printing ink is lighter, the ink layer is thinner, the color brightness is lower.
2. Letterpress printing: It is a commonly used direct printing method, which is characterized by a thick ink layer and a strong gloss. When the printed matter is observed with a magnifying glass, the lines and the drawing are recessed, the flashes are prominent, and the strokes are not neat.
3. Gravure printing: It is a kind of special printing method, which is characterized by thick ink layer and strong gloss. "China Printing Industry Branch Technology Information Network"
