Printed material security technology. Application materials and new printing technology anti-counterfeiting technology in the printing part of an important role to play. We contacted all kinds of fluorescent ink, from the early 90s of last century by large-scale application in the country, manufacturers are competing applications, and did achieve a certain security role, followed a number of new fluorescent materials in the application of currency security printing materials has promoted the development of ultraviolet, infrared light, light induced change materials, and many new materials and applications, security inks and other materials to continue to play a security function.

With Printing Supplies Development of extensive, UV technology and scientific and technological progress in many chemical materials, including nano-materials development, the future application of ink and other supplies on the counterfeit material may have more development space, but still have two major areas to ensure that the application of flexibility and ease of detection.

Shading security Printing plate Design The anti-counterfeiting technology. Shading is the lowest-cost anti-counterfeiting, security is better as a security printing technique.








Shading the main features of anti-counterfeiting


Full use of the line for security, can produce a wealth of change, security design plate to complete the process, to achieve in print. Can also be based on optical, spectroscopic techniques, printing technology and other technical principles, use of shading to achieve security, such as refractive authoring software, latent image and other security applications. Shading or other security elements will not affect the overall design style of print, because the security elements such as floral, latent image, microfilm general application in the local language, does not affect the overall style. Comparison of printing color shading is usually light, will not affect the aesthetic effect. The depth of color the human eye can be considered and Scanners Applied Optics distinguish the difference of color to set, so that the scanner does not scan them, but the human eye to distinguish.








Like relief, refraction, lace and other effects added for the designer? Kinds of new design elements, and traditional design with design ideas can be better, play a beautiful, smart, easy to understand, highlights security effectiveness . Commonly used in security printing shading elements are: floral, Curve relief, image relief, lace, latent image, microfilm the text, shading, variable width, curve simulated images, refraction, graphics filtering. Security shading can be understood as two aspects of security:








prevent counterfeiting ? Aspects of imitation are printed on the copy is difficult to produce with ordinary software similar effect, on the other hand is even with the same? Pieces of software are difficult to counterfeit.








Such as Peking University Founder Ultra-line security system uses the line shading design is a sine line, while the sinusoidal line is very difficult to hand-painted with a common software out, providing floral, Curve relief, lace, image relief, thickness changes of the line, curve simulated images in the production of great random, even using the same software to copy is too difficult to make a mold? like.








Image relief, curve simulated images of these features, in the end product: the performance of the line describing the image effect, if not the original raster image, is impossible to make the same effect, but also can not scan out of.








Anti-scan To modern ultra high-precision (more than the optical resolution of 5000dpi) scanner or camera-ready version can not reproduce the line profile can prevent scanning. Factory safety shading design work itself has anti-scan feature, the reason is very simple, scan the resulting image must be a network, and security lines formed by shading, and therefore can not be scanned.








Security shading design is to increase the product value-added applications? An effective means of printing enterprises, but can also develop some of the special printing business. Higher profits in the printing industry in the use of special printing a large number of shading technology and security applications in each product (checks, stamps, books, passport, documents, etc.).
