Anti-counterfeiting paper: Paper is the basis for printing various materials

Paper is the basis for printing various materials. Some special papers manufactured using special processes basically have security features. The anti-counterfeiting technologies used in special papers are:

1. Watermark paper

The watermark paper production process was invented by Italian papermaking experts in the 13th century. Because it integrates the complex processes of design, engraving, web making, and papermaking in the manufacturing process, it often makes counterfeiters useless. Checking the watermark is also one of the most effective means to identify true and false. Of course, the use of watermark anti-counterfeiting on a large number of packaging devices is not economical at this stage.

During the manufacturing process, watermark paper can use technical means to incorporate the required logos and patterns into the paper. These patterns are not easy to see under normal circumstances. Only when facing the glare can we see that most of the larger denominations issued in China are Watermark paper printing is used. Watermarks are still recognized by world security experts as an effective anti-counterfeiting technology in today's advanced science and technology era. They continue to be adopted and developed by all countries. Most countries have banknotes, important international documents, and drawings of facilities. All kinds of tickets are also printed on watermarked paper. For example, in the new version of $100 paper in 1996, the "Blue Colin" portrait watermark was used, and watermarks such as "Tiananmen" and "Mao Zedong" were produced in large-value RMB paper in China. 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.

2. Security line

The safety line refers to placing a gold or plastic line in the middle of the paper during papermaking. In recent years, with the rapid development of high technology, papermaking technology has made great progress after integrating other technologies, and the variety of paper products is dazzling. If they can reasonably use their performance, characteristics, and control the purchase channels, as anti-counterfeiting printing paper, the effect and force generated cannot be underestimated.

3. Red and blue fiber or color points

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