The role of secure graphic design in the whole anti-counterfeiting printing

with the increasingly extensive and in-depth application of digital technology in printing and various fields, secure graphic design is increasingly closely combined with computer technology, and continuously improves the design and anti-counterfeiting level of anti-counterfeiting printing. Just as the importance of design for printing, secure graphic design has always played a very important role in anti-counterfeiting printing

1. Connotation of safe graphic design:

safe graphic design is also known as pattern design, flower ball design, twisted rope decoration design and shading background design

this is one of the oldest and longest lasting anti-counterfeiting technologies. This kind of background picture and text can be seen on the familiar banknotes, passports and cheques

the current safe graphic design system is combined with computer technology, which can be designed according to the user's own style, and can design a complete graphic background and related text with distinctive personalized characteristics, such as flower ball, microfilm, microfilm, anti scanning graphic, anti copy graphic, relief pattern, invisible graphic design, line splitting effect, printmaking effect, etc

these pictures and texts adopt line design and spot color printing, which can effectively prevent color separation printing and color copying after being copied by traditional means such as electric separation, photography and scanning, and play an obvious anti-counterfeiting role. For example, a line with uneven thickness is difficult to copy, so this secure graphic design is still widely used in the production of banknotes, cheques, important national certificates, securities, etc

2. Basic anti-counterfeiting principle of safe graphic design

use the anti-counterfeiting design system to make various line effects, and achieve the purpose of anti-counterfeiting by preventing scanning. Even the scanner or photographic plate making with ultra-high precision (optical resolution above 5000dpi) can not reproduce the line shape of the pattern. After scanning the thick and thin lines, they will become a dot matrix image rather than a vector graphic, so the weak thickness change of the lines will be lost. In addition, the spot color lines must be separated when outputting, and they will become a dot graphic after color separation. There will be a great loss if overprinting is not accurate. In this way, the output of the scanned thick and thin spot color lines will be very different from the original products, which can be easily identified by the naked eye, so duplication can be prevented, So as to achieve the purpose of anti-counterfeiting

the primary means for counterfeiters is to copy by scanning. To prevent scanning is to protect the legitimate rights and interests of users. For the line works designed by the anti-counterfeiting design system, after printing the finished product, the color of the line is the field, while the scanning generation is the point, which can be distinguished with a magnifying glass

the safety graphic design works have good anti scanning function, because the results generated after scanning must be point graphics, while the products designed with anti-counterfeiting are composed of lines. Scanning copy can copy an ordinary line, but it can not recognize double color lines, only single black lines; Lines with thickness changes cannot be recognized, but lines with uniform width can only be recognized; At the same time, lines and points cannot be recognized at the same time

3. The basic content of safe graphic design

the elements of safe graphic design are divided into a variety of types, including shading, newcord decoration flowers, lace, microfilm, latent image, anti scanning, anti copying, relief, line splitting, invisible graphic, printmaking effect and image processing, comprehensive image, colorless fluorescent pattern design, etc. Each function can be used alone or integrated to form more complex patterns

shading: the elements are changed repeatedly to form a continuous pattern, which is regular, continuous, penetrating and changeable. Shading is mainly used as a foil and foil. It is generally lighter and shallower, and the lines are relatively sparse and thin. At first glance, only a layer of plain and light background color can be seen. When you look closely, you can find the changes. There are many kinds of shading changes: flat background, gradient background, wave background, etc

since the shading is composed of elements, and the material of elements is unlimited, the application range of shading is unlimited, and its change form is extremely random. For example, shading is widely used in bank certificates of deposit, certificates, tax receipts, etc., which is both beautiful and anti-counterfeiting

tassel rosette: we call it tassel rosette, which is processed by various shapes of lines, exaggerated, matched with the radian and density of lines, and complemented by color, to make its contour smooth, level clear, reasonable structure and shape independently

Lace: one or several elements are continuously copied to form a frame form to form lace. Lace is made of elements and can change freely. Lace mostly plays the role of decoration on four sides. For example, a group of lace that cuts, splices and arranges a variety of cluster flower elements in a regular manner has bright colors and can be used for peripheral decoration of certificates and documents

relief: it refers to the use of line shading as the bottom, combined with the background picture (logo or text) for relief design, so that the picture can produce a concave convex effect like sculpture. Embossed high thermal conductivity, low expansion electronic packaging and heat sink material technology can be said to be very common in real life. For example, the Relief Shading on the train ticket, air ticket, air ticket insurance policy, bank passbook, and various documents and bills of the state government are all printed with various forms of relief shading, which can well transfer to the user's own corporate image on the premise of fully ensuring anti-counterfeiting

latent image: it can be understood that words or graphics are hidden in the newcord decoration pattern, which is called latent image. It is divided into offset latent image and gravure latent image. Among them, gravure latent image is more effective in anti-counterfeiting and identification. This technology comes from the banknote printing technology. It is printed by a special engraving gravure printing machine and has an obvious hand feeling effect by touch. For example, the newly issued fifth set of RMB is applied to all banknotes

miniaturization: the anti-counterfeiting principle of this form is to reduce the height of Chinese characters to less than 0.22mm and that of English characters to less than 0.2mm. We call it miniaturization. Miniaturization is the simplest method in anti-counterfeiting design, which can be combined with other functions as required. The characteristic of miniaturization is to replace lines with words. A thin line, when you look at it carefully, you find that it is composed of words. Combined with other functions of shading, you can generate many changes to the text lines. For example, a miniature text interwoven with Chinese and English, which interweaves and arranges the Chinese and English text in the form of arc, breaks through the single expression of the text flat, which is not only rich in changes, but also plays a role in anti-counterfeiting. This form of anti-counterfeiting means can be applied to certificates and cards, and can be used to make microfilm shading or microfilm lace. Another example is to make a group of words into a smooth curve, which is cleverly intertwined to form a flower shape, which is exquisite and unique, with rich and diverse changes

anti scanning and anti copying: the anti scanning and anti copying effects are obtained by using the design combination of various changes of lines: Line directivity, line fineness change, splitting technology, composition form, color change, sensitive color, etc

line splitting: the technology of splitting a line with a certain fineness into two lines. The fineness of the line is reduced by half, and the text or logo are combined to achieve anti-counterfeiting effect and personalized design

in the practice of anti-counterfeiting, the wide application of secure graphic design in high security products, such as passports, visas, banknotes, cheques/money orders, etc., has improved the aesthetic feeling and anti-counterfeiting ability of such items, making them able to resist counterfeiters in an all-round way. At the same time, it has also kept pace with anti-counterfeiting media (raw materials), printing technology, etc., becoming one of the three main forces in anti-counterfeiting printing

3. The basic process of security graphic design

security graphic design is mainly composed of overall design, pattern design, color design, font design and computer shading design. These designs also take into account the selection of anti-counterfeiting raw materials and printing process

generally, for a design, the customer provides the scheme or sample or design parts or modifies the existing things. According to different design expertise, a Zimmer project team is formed to put forward the design draft within a certain period of time, negotiate with the customer after being approved by the artist or design director, and provide effect samples. After the confirmation of the customer, we will design the computer and make the real Newcastle ornaments. Finally, the film is produced for plate making, but it also meets the standards for delivery and printing. The design department is fully responsible for the quality management of this process until it is signed for approval

4. From the basic process of security graphic design, we can see the important position and role of security graphic design in the whole anti-counterfeiting printing, and the requirements for the quality and ability of security graphic designers are also quite high. Carefulness, patience, steadiness and sense are the basic requirements for quality. At the same time, the basic concepts of color sensitivity and beauty are also necessary. Designers should not only be familiar with various anti-counterfeiting media, such as safety paper and safety ink, but also understand various printing methods and processes, and even the technical ability of various printing and reproduction means. Designers should have the ability to continuously study, investigate, collect and obtain all kinds of forged information, and be able to develop new technologies or propose new topics for the research and development department

the designer must know the production process and the effect of drawing a line in production. Designers should learn to constantly communicate with plate making and production personnel to revise the design and accumulate experience

in a word, the security graphic design department is the top priority of the anti-counterfeiting printing factory because of the importance of their work. The nature of their work gives them more opportunities to become experts in the field of anti-counterfeiting printing. The anti-counterfeiting printing factory also has the core competitiveness and high-end talent advantage because of their possession
