International high-end security paper technology

As we all know, security thread paper, especially implanted window security thread paper, has been developed for nearly 30 years. Although the visual recognition technology on the line has been developed, there is limited space for development. As a raw material for banknotes, the technology of banknote paper has been continuously developed and continuously innovated, especially with foreign technology development being more innovative and creative. It is worth our reference and learning, and we have created new ways and created something unique.

All along, our choice of anti-counterfeiting technology is based on Highly visual; Easy to recognize; Extremely complex to copy; From the above three aspects, foreign counterparts have developed a lot of amazing Anti-counterfeiting technology: Guardian, OPTICKS, Motion, Varifeye, etc. are the best of these technologies, and are briefly introduced below.

1. Australian Guardian plastic banknotes and G-Switch technology

Plastic banknotes were first developed by the Federal Reserve Bank of Australia (RBA) and the Australian Federal Institute of Science and Research (CSIRO) and became the first Australian currency to be issued in 1988. The key technology of plastic banknotes is the plastic substrate: biaxially oriented polypropylene film and its coating, registered as Guardian. Plastic banknotes developed rapidly in a relatively short period of time and completely replaced DuPont's Tyvek polyethylene fiber film technology. Guardian technology films are fiber-free moisture-resistant plastics that are more difficult to tear, durable, and less likely to leave creases than paper-based bills, are not easily resolved in the soil, are easy to machine, and are recyclable. The life of plastic banknotes is 4 to 5 times longer than paper banknotes.

All anti-counterfeiting features on paper banknotes can be applied to plastic banknotes. Whether it is gravure, letterpress, offset printing or implanted security thread technology, its greatest advantage lies in its ability to implant the latest and most advanced optical security features such as transparency. Windows, diffraction gratings and holograms. The transparent window is a key security feature of plastic banknotes, and anyone can instantly recognize the authenticity of the plastic banknotes based on this feature. Plastic-based banknote anti-counterfeiting technology still has a lot of room for development. Currently developed OVD, G-Switch and other technologies, followed by the United Kingdom, Germany, the United States and other development of the film paper combined with banknote material technology are inspired by the Guardian and the end result .

G-Switch is the latest color security feature of Guardian plastic banknotes. It is one of the best anti-counterfeiting technologies of the year 2005. It is a dynamic optical feature that changes the original color when a banknote is tilted under a special light source. The bright, instantly-changing color conversion effect is formed in the substrate coating. When viewed from different angles, the banknote changes between the two contrasting colors to produce an optical refraction effect. The change of color can be easily distinguished without any special equipment or skills, making it easier for the public to identify the authenticity of the banknotes. The colors and designs on different banknotes can have different color combinations. The advantage of the G-switch is that electronic print forgery cannot be achieved; the construction of this feature makes the banknote very durable. This anti-counterfeiting feature is built into the substrate structure and is cost-effective and suitable for low denomination banknotes.

2. UK OPTICKS Technical Paper

De La Rue Portals' Optiks is a high-tech, high-value product that combines traditional papermaking with new materials and new technologies. Optiks is a wide 18mm pattern aluminum foil strip that can be placed in a set pattern with a transparent window that can be seen through a transparent strip film.

Its features are: unique through-hole; obvious 18mm-wide custom-made de-aluminum shading customized image; in the process of circulation, the metalized image is clearly visible; the fluorescent band on the graphic under the ultraviolet light is clearly visible;

This is one of the typical techniques that traditional watermark paper technology can be well integrated with new optical technologies.

3. Swedish MOTION security thread paper

The Motion Safety Line, also known as the Motion Safety Line, is a micro-optic based material used on banknotes. Its image can change depending on the perspective. This constantly changing dynamic image can be easily identified based on the appearance of the image and a tilting method that people gradually find out. This remarkable effect quickly attracted people's attention and curiosity, making it the most ideal anti-counterfeiting means.

This dynamic security thread technology can be applied independently to banknotes and is entirely owned and controlled by CRANE CURRENCY, Sweden. Its microlens structure is a unique and protected process; it uses unique and controlled materials; it has unique and densely built independent intellectual property rights.

The dynamic effect is remarkable by a series of micro-optical lenses and a predetermined set of images. The magnified image changes as the visual changes. This kind of dynamic safety line technology does not rely on electric light sources, and these changing images are observable even under relatively dim lighting.
