Anti-counterfeiting technology application in security printing

Common anti-counterfeiting methods include anti-counterfeit paper, anti-counterfeiting ink, code anti-counterfeiting, and laser laser anti-counterfeiting. Among the numerous anti-counterfeiting technologies, anti-counterfeit forkprint is applied in various anti-counterfeiting fields such as currency, ticket, and commodity packaging due to its good effect, economical and practical advantages, and the prospect is very broad.

1 The characteristics of anti-counterfeit pattern

The main features of the anti-counterfeit version are the complete use of lines for anti-counterfeiting, and can produce a rich variety of changes. The anti-counterfeiting design is completed in the plate making process and is realized in printing without additional production cost, high anti-counterfeit performance, and general general software cannot be copied. The effect of this line. The composition of the anti-counterfeiting design system is divided into various types, including: ground grain, flower, lace, miniature, latent image and so on. Each function can be used alone, or you can combine several functions.

2 version of the main features of anti-counterfeiting

1) Landmark

It is to change the elements repeatedly to form a continuous pattern of texture, which is called ground pattern. Applying textures to life can be said to be abound. The most obvious one is the banknote. Another example is the bank's certificates of deposit, certificates, tax stamps, etc. are used in a large number of patterns, some patterns are the use of different colors of several sets of curves, using divergent methods, so that the entire pattern has a divergent effect; some patterns It is a pattern with embossed effect. It is a combination of pattern and picture. The effect of the pattern is like stone carving, which is both beautiful and anti-counterfeiting.

2) Flower

It is processed in various shapes of flowers. Cluster flower is a very important function in the pattern system. It can be used alone, and it can also be used as an elemental effect, such as flower lace, flower pattern, and flower relief. Some flowers are produced using a variety of organic combinations, using lines of density, elasticity, interspersed, and enhance the level of group flowers and float. Applying it to documents, documents, banknotes, and packaging boxes has a good anti-counterfeiting effect, but also has a good artistic appreciation.

3) Lace

It is the continuous reproduction of one or more elements that form the various forms of the frame, which we call lace. The material of the lace comes from the elements and changes freely. Its structure can be divided into totally enclosed and semi-closed structures according to structure; it can be divided into single-layer lace, multi-layer lace, single-line lace and other forms according to the production form. As the composition of the lace is in the form of a frame, most of the laces play a decorative role on the four sides, such as a group of laces that cut, splicing, and regularly arrange a variety of flower elements, and are brightly colored, and can be used for the decoration of certificates and documents. .

4) Relief

It is the use of lines and patterns as a background, combined with the background image after the embossing process, so that the screen produces a sculpture-like bump effect, we call it embossed. Even the relief of the same pattern and picture, according to its different settings, can also change many different shades of effect. A kind of relief made by using the interference phenomenon of light has the effect of unlocking and the like. The application of reliefs in real life can be said to be very common, such as embossed patterns on bankbooks, various documents of national government agencies, documents, bills, etc., all of which are printed with various forms of embossed patterns. Various company logos are seen on the logo relief and so on. It fully conveys the company’s own corporate image under the premise of full security protection.

5) Latent image

It can be understood as an anti-counterfeiting technique that hides text or graphics in print. The principle is to infiltrate other elements in a picture, such as hiding text or graphics in prints or flowers. The latent image technology is excavated from the banknote printing technology. For example, the actual use of the latent image is found in the new-top version of RMB 50 and RMB 100 in the top-right cluster. With the latent image generated by the stencil design system, a good anti-counterfeit effect can be achieved on an ordinary high-precision printing machine, and the same effect as that produced by the banknote printing machine, but the type not printed by the banknote printing machine is looming. Effect. The surface of the latent image generated by the stencil system looks like a pattern. Only careful observation can discover the mystery. Its anti-counterfeiting performance is very strong.

6) Microfilming

Its anti-counterfeiting principle is to reduce Chinese characters to within 0.22 mm, and English characters to be printed within 0.2 mm. Microfilming is the simplest method to use in the stencil system and it must be combined with other functions. Microfilming is characterized by the ability to replace characters with a thin line. When you look closely, you discover that it is composed of words. In combination with the other functions of imprinting, you can make many changes to the text. This form of anti-counterfeiting can be applied to documents and cards.

7) Embossing

Nowadays, some embossed packaging products can be seen on the market, such as embossed packaging of cigarette packs, embossed packaging of wine boxes, and so on. It is entirely through the use of lines to go through different directions, the thickness and spacing of lines, and the use of the principle of light reflection to form the center of divergence. With the effect of rotating or rotating, these lines can be made into metal plates by physical or chemical action, pressed on the packaging box of gold and silver cardboard, and added with color to create a beautiful embossed pattern. painting. The advantage of embossing is that it can produce a refraction effect, which can be divided into two types of graphic refraction and image refraction (graphic refraction is mostly used in cigarette cases, wine cases, medicine boxes, and cards, and image refraction is mainly used in the production of handicraft metal paintings).

The latest embossed version of the stencil design system can be used to create a variety of embossing effects with the unique line function of the stencil design system, which better meets the needs of the packaging market. Embossed version not only can produce a variety of different forms of line embossing effects, such as: linear embossing, arc embossing, triangle embossed lines, wavy embossed, concentric embossed, concentric rectangular embossed, etc. Can produce a variety of image embossing effect.

8) Anti-scan

It is a line pattern of a print that cannot be copied even by a high-precision scanner and is called anti-scanning. The layout design system was developed based on the limitations of the scanner. The anti-scanning pattern can completely eliminate scan copying. The typical anti-scanning is a circular line-graded anti-sweep, mainly through the change of the distance and thickness of the concentric circles, so as to achieve a seemingly three-dimensional sense, which can substantially make the scanned image unable to achieve this effect. Its anti-counterfeiting performance.

9) Image Processing

It is the use of various trends, a variety of shape lines, combined with background images suitable for their own applications, image processing technology. This function of image processing is a kind of anti-counterfeiting method with a special presentation mode in the pattern printing system. The works generated by this function are initially all kinds of different pictures, but as long as careful observation, you can find the Mystery, the image effects of all image processing works are composed of lines. In addition, graphics filtering and fisheye conversion are also available.

3 Several Common Anti-counterfeiting Pattern Systems

1) Founder Super Line Advanced Pattern System

Founder ultra-line anti-counterfeiting has the following characteristics:

1 in line with the principles of packaging design, design patterns, group flowers, lace, embossing, refraction, latent image itself belongs to the plate making, more eye-catching and easy to understand, and difficult to counterfeit.

2 anti-counterfeiting effect is good. The pattern produced by using the Founder Superwire is difficult to imitate, and even if the same designer uses the Founder SuperLine, it cannot be guaranteed to be exactly the same at different times, not to mention different designers.

3 Low cost. The system using the Founder Ultraline can be completed in the normal packaging and printing environment.

4 strong compatibility. Since the design software used in packaging and printing design is generally Illustrator, CorelDraw, Free-Hand, and anti-counterfeit version design software is not compatible with these softwares, for example, the results of anti-counterfeiting design software design cannot be used in Illustrator. CorelDraw, FreeHand these software to do modification, coloring, trapping (trap) and other work. The Founder SuperLine software can directly generate files that support PC and Apple platforms, and can be directly opened with software such as Illustrator, CorelDraw, FreeHand, etc., to do modification, coloring, trapping (trap) and other work.

2) Features of JURA Software

JURA is an internationally renowned coin-making and anti-counterfeiting version of the software developed by Hungary. It has a history of more than 10 years. Nowadays, it has been updated constantly and has formed its own unique high-tech anti-counterfeiting features, which are mainly manifested in the following aspects.

1 software design ability. JURA software can use user programming, parameter control and other methods to generate floristry and lace. The processing method is simple and the effect is better.

2 Add a variety of new features. Apart from being able to loosely design elements such as floristry, lace, line width changes, and miniature texts that are difficult to achieve, software also adds high-tech content.

One is to add the latest anti-copying technology. After this technique is applied to anti-counterfeit products, counterfeiters will appear on the copy when copying through color scanners or copiers, such as "defective goods", thus eliminating the possibility of copying.

The second is to increase the screening function. Any element or letter can be used instead of dots to fill a picture, and unit information can be added at random, thereby improving the anti-counterfeiting effect. The plain imprinting software does not have this function, so the imitation is more difficult.

The third is to increase personalized security. For personal anti-counterfeiting, personal information is added to the picture on the certificate, and the personal information on the portrait can be seen through the magnifying glass. This personalized anti-counterfeiting is the highest level in anti-counterfeiting. It can achieve that each anti-counterfeiting certificate has a different anti-counterfeiting version pattern, so that the copy-maker can't deal with it. This is something that ordinary software can't match.
