Today, the editor will share with you the application field of an cij printer, the printing of stamps.

First, the necessity and realization of coding on stamps.

Identification and anti-counterfeiting. Here I want to test my friends, what is our country’s first stamp

? In 1878, the customs of the Qing Dynasty tried to run the postal service, and issued China’s first set of stamps—Large

Dragon stamps. There are 3 stamps in this set. The main picture is a symbol of the Qing imperial family. --coiled dragon. 'Dalong Post

Ticket' is considered to be the first set of stamps issued in my country. In the beginning, the markings on stamps were for marking, but with the development and progress of the times, stamps are not only used for mailing, but also have a collection value. There is a special trading place, which involves distinguishing the authenticity of stamps. Another function of the mark is the appearance of anti-counterfeiting.

Second, the development history of stamp coding.

With the improvement of printing technology, China Post has also added many new technologies to stamps, and the use of fluorescent coding is an important one. 'Fluorescent coding' is also called 'invisible

coding, which is invisible under sunlight, but can appear under ultraviolet light.

The history of China Post's use of fluorescent inkjet coding on stamps can be roughly divided into three stages: the first stage (1999-2000).

One of the stamps in the full-page stamp uses fluorescent coding. In the second stage (2000-2002), after 20 months of operation and practice, there have been major changes and breakthroughs in the application of fluorescent coding. By June 29, 2002, the '2002-14 Desert Plants' stamps were issued, during which 46 sets of Gite stamps were issued. The proportion of fluorescent coding for these 46 sets of stamps has been greatly improved. This process of careful operation, adjustment, and improvement has laid a solid foundation for fluorescent inkjet printing.

The third stage (2002-present) fluorescent inkjet tickets have achieved a veritable anti-counterfeiting function.
