As one of the three major production units of China's precious metal commemorative coins, Shen Min coin has also developed a large number of craftsmanships in this regard. The gradual maturity of anti-counterfeiting technology applies precious metal commemorative coins to products that use anti-counterfeiting methods to show unique artistic effects. While promoting the art of precious metal products, the level of anti-counterfeiting of precious metal commemorative coins has also increased. The following introduces several anti-counterfeiting technologies applied to precious metal coinage.

  The commonly used anti-counterfeiting technologies for metal commemorative coins are as follows:

   Multi-face invisible carving technology

  Multifaceted invisible engraving technology is a wide range of anti-counterfeiting technology independently developed by Shenbi. Its effect can alternately appear different images according to the viewing angle. An image can be viewed from a certain angle. If the engraving surface is tilted or reversed, the image will disappear and other images will appear.

   Miniature Pattern Technology

   The so-called miniature age and technology is used as computer-aided design software, text, text and pattern production, using laser engraving machine coin type and through the press printing process, so that these attractive ages are transferred to jade forged products, and the purpose of improving product performance.

   fine pattern technology

   Fine pattern technology is the use of optical principles, the use of optical principles, laser technology engraving, and parallel dedicated software to design and produce the age of line combinations, such as ground patterns, reliefs, flowers, invisibility, etc., anti-counterfeiting technology. It adopts the anti-counterfeiting form of the complete combination of dots and lines, showing a wealth of patterns such as curves, thickness, Yin and Yang lines. This technology has high anti-counterfeiting performance, and cannot be forged in general software, spray processing, laser scanning and other methods. The micro-pattern technology is a brand-new embossing processing technology, which can express the unique artistic features of the subtleties without losing the beauty of the overall currency surface. This technology is applied to the 5 oz silver coin products of the Youth Olympic Games, using fine pattern engraving technology, very good reproduction of Nanjing Yunjin art, with superb anti-counterfeiting technology, the expression of artistic effects.

  Laser Shadow Technology

   This technology is used in high-precision laser engraving machines. First, the effect of laser sandblasting is made by using type cloth, and then the different levels and effects of laser shadow (year and text) engraving on the bottom and sandblasted surface show the effect, compare Concealed, the role of anti-counterfeiting marks. This technology requires high precision and technical parameters of the laser engraving machine, and it is currently difficult for counterfeiting technicians to imitate it. Minting is the original coinage of precious metal Shen, mainly used in new anti-counterfeiting technology, the young Obama 5-ounce silver coin product in 2014.

   Ultra-micro engraving technology

  Ultra-engraving, as a kind of surface, widely uses fine processing technology for the processing and production of various fine graphics and fine carving structures. The small age line width is 0.1μm. Shen Coin applied this anti-counterfeiting technology to the production of long film products, micro-engraving more than 200 movie names and more than 700 Chinese characters in two diamond-shaped boxes of 2.5 mm × 2.5 mm, and observed with a 40-fold magnifying glass. The strokes are clearly visible.

   Of course, the anti-counterfeiting of precious metal products also includes four corners, polygons, plum blossoms, holes and other structures. The development of special-shaped precious metal products with distinctive characteristics is also the current and future project of Shenhuo. In the production of precious metal products of Shen Mint, it has always enriched the gold and silver commemorative coins through the application of a series of innovative anti-counterfeiting technology, and prevented the appearance of counterfeit products from showing an improved level. The improvement of the artistic level of various types of products is moving towards one after another. A new step.
