Commercial paper printing security technology

Anti-counterfeiting technology for printed materials. The anti-counterfeiting technology using printed materials and new processes plays an important role in the printing process. The various kinds of fluorescent inks that we came in contact with have been widely applied in the country since the early 1990s. Manufacturers have also rushed to them, and they have indeed achieved certain anti-counterfeiting effects. As a result, some new fluorescent materials have been used in currency applications. It promoted the development of anti-counterfeit printing materials, application of many new materials such as ultraviolet light, infrared light, and photo-mutation materials, so that anti-counterfeiting inks and other materials will continue to exert anti-counterfeiting functions.

With the widespread development of printing consumables, UV technology and many scientific and technological advances in chemical materials, including the development of nano-scale materials, the future of anti-counterfeiting materials used in ink and other consumables will have a relatively large space for development, but the main link is still There must be two guarantees, namely the flexibility of application and the convenience of detection.

The application of anti-counterfeiting technology in printing plate design. Anti-counterfeit shading is an anti-counterfeiting printing technology with the lowest cost and better anti-counterfeiting effect. The main features of shading anti-counterfeiting are: full use of lines for security, can produce: cattle rich changes, anti-counterfeiting design is completed in the plate making process, in the printing. According to the principle of various technologies such as optics, spectroscopy, and printing technology, shading security creation software can also be used to realize various anti-counterfeiting applications such as refraction and latent images. Shading or other anti-counterfeit elements will not affect the overall design style of the print, because anti-counterfeit elements such as flowers, latent images, and microtext are generally applied locally, without affecting the overall style of the design. The shading printing is generally lighter in color and does not affect the aesthetic effect. The depth of the color can be considered by the difference between the human eye and the scanner application optics for color resolution, so that the scanner can't scan out and the human eye can distinguish.

Effects such as embossing, refraction, and lace increase the number of new design elements for designers, and they can provide better design ideas with the traditional design. They can be beautiful, eye-catching, easy to understand, and highlight anti-counterfeiting effects. Commonly used in the printing of security shading elements are: flowers, curved relief, image relief, lace, latent image, microtext, shading, wide line, curve simulation image, refractive, graphic filtering. Security shading anti-counterfeiting can be understood in two ways:

1 Preventing counterfeiting

The copying of the printed matter is difficult for the copy maker to produce a similar effect on the copied product. On the other hand, it is difficult to imitate even using the same software.

For example, the lines used by the Beijing University Founder HyperLine Safety Shading Design System are sinusoidal lines, and sine lines are difficult to hand-painted with general-purpose software. The provided flowers, curved reliefs, laces, image reliefs, lines of varying thickness, and curves Simulated images, etc., have a great deal of randomness in production, and even if they are copied using the same software, it is very difficult to make a model.

The functions of image relief and curve analog image are shown on the finished product: the image effect described by lines. If there is no original image, it is impossible to make the same effect, and it is impossible to scan out.

2 Anti-scan

Ultra-high-precision (optical resolution 5 000 dpi or more) scanners or photoengraving plates are also not able to reproduce the lines of imprinting patterns to prevent scanning. The works of the factory security shading design itself have the function of anti-scanning, the reason is very simple, the scan generated must have the image of the dot, and the security shading is composed of lines, so it can not be scanned.

The application of security shading design is an effective means to increase the added value of products, and it can also expand certain special printing services for printing companies. In the printing industry, profitable special printing uses a large amount of security shading technology and applies it to each product (cheques, tax receipts, passbooks, passports, certificates, etc.).
