The reform and opening up stimulated the development of the commodity economy, and people's material living standards have also greatly improved. However, due to various reasons, consumer markets have gradually increased the number of counterfeit and shoddy goods in recent years, and their potential has intensified. Consumers have been deceived by counterfeit cargo pits in the sea of ​​dazzling commodities and their interests have been greatly hurt.
According to relevant statistics, the world has caused losses of as much as 100 billion U.S. dollars in the world economy and industry due to the counterfeiting of various high-end branded goods and fake tickets. In the international market, there have been more than 2,000 counterfeit and shoddy commodities recorded in only five years. What is even more worrying is that in the fields of medicine, food, tobacco, alcohol and beverages, counterfeit packaging is even more rampant and often makes it hard for air defense. Not only does it cause economic losses, it also directly threatens people's health and lives. People began to study and seek a means to prevent counterfeiting and stop shoddy products. Thus, a special printing technology - anti-counterfeiting printing technology was born.
Overview of Anti-counterfeit Printing Technology Counterfeiting has existed since ancient times, and anti-counterfeiting is also as old as human civilization. The use of fingerprint anti-counterfeiting is probably the oldest anti-counterfeiting method. It has not only been used since ancient times, but it has also been combined with modern computer identification technology and has achieved unprecedented widespread use. It can be said to be new and brilliant.
Many anti-counterfeit methods have borrowed the results of printing technology and played an important role in anti-counterfeiting. However, some of the counterfeiters that came with it also used related technological methods to engage in counterfeiting activities. With regard to falsification technology related to printing technology alone, criminal activities such as counterfeiting currency, securities, documents, documents, certificates, credit cards, contracts, trademarks, logos, packaging, stamps, famous paintings, precious stamps, and stamps have been widespread. In many parts of the world, it is also banned repeatedly in our country. According to statistics, there are 2 billion U.S. dollars forged each year, and 2 billion for U.S. banks with fake credit cards, and 3 million fake passports worldwide.
In our country, the sea seized a smuggling case valued at RMB 27.7 billion from 1987 to 1996. The means of committing the crime were mainly false documents, false approvals, and false seals. In 1996, Kowloon Customs identified 203 counterfeit import declarations for the Guangzhou and Shenzhen Foreign Exchange Administrations and found that it had defrauded the country to reach US$700 million. As for those individuals or dens that are scattered all over the country, they are making and selling fake ID cards, driver's licenses, diplomas, and other documents. Faced with such rampant falsifications, we earnestly hope that printing technology can go a step further and apply the results of multidisciplinary research to printing, so as to further improve and enhance anti-counterfeiting technology.
In recent years, the development, production and sales of anti-counterfeit printing technology in China have formed a new industry of anti-counterfeit printing technology.
The anti-counterfeiting technology achieved through the printing process can be referred to as security printing technology. Anti-counterfeiting printing technology involves many subject areas, such as optics, chemistry, electromagnetism, computer science, spectroscopy, printing technology, pattern code technology, etc., belonging to a cross-edge discipline. Among them, chemical anti-counterfeit materials and technologies are one of the most basic technologies for anti-counterfeiting. The anti-counterfeit ink technology in which it occupies a very important position, has an irreplaceable role.
The so-called anti-counterfeiting ink, that is, adding a special performance of anti-counterfeiting materials in the ink chain material, processed by a special process of special printing ink. The specific implementation is mainly printed on the ticket, product trademark and package by ink printing. This type of anti-counterfeiting technology is characterized by simple implementation, low cost, good concealment, bright colors, easy inspection (even hand-warming color change), and strong emphasis. It is the preferred anti-counterfeiting technology for banknotes, tickets and trademarks in various countries. (To be continued)
