With the product's economic development, people's material standard of living is also rising. The consumer market of fake and shoddy goods on the rise. Consumers even more concern is that alcohol and tobacco, beverage, pharmaceutical, food areas, counterfeit packaging often makes very hard to detect, not only to consumers and manufacturers have brought economic losses but also endanger the health and lives of consumers. At the same time enjoy the win for some long-standing reputation of the brand-name merchandise brought bad influence. In the printing industry there is a special printing technology, it is security printing.
1, anti-counterfeiting Screen Printing Ink
The security features for screen printing inks are heat-sensitive ink, light-sensitive ink, magnetic ink, fluorescent ink, anti-altered ink and so on, the ink used in anti-counterfeiting packaging has a certain security role.
1. Thermochromic ink
Refers to a certain thermal conditions caused by the outside world, the color will change. It can be divided into two categories: one category is available plastic, that is caused by a heat source heat discoloration removed, ink color can also restore the status quo ante; the other is not plastic, that is, heat can not be recovered after the withdrawal of ink colors. According to customer requirements, production of special design or logo version, using thermochromic ink to the packing of the shelter, or any specified location. When the Verify the authenticity of goods, the use of a certain temperature heat source, such as lighters, matches, pour boiling water cups, hot hair dryer etc. baking, markings produced parts immediately obvious color changes, hidden identity also appeared in succession, can be quickly identified out the authenticity of goods.
2. Photochromic ink
Photochromic ink can be divided into two categories: the ordinary type, refers to the ordinary role of sunlight and strong lights, the ink color change occurs from the deep-shallow or light, become darker in color becomes colorless, with or without at the mere mention of color. To leave the light source would be to restore the status quo ante, the ink applied on the packaging can not only improve the product grade, increasing fun, highlighting the role of anti-counterfeiting. At the same time can be printed with ordinary ink on the Shading printing "false invalid" and other words and then cover the photochromic ink coating to make it hidden. And those that the UV type, refers to ink colorless in ordinary light irradiation, or can not afford to change, but, under ultraviolet light will show bright red, orange, yellow, and green, and green fluorescence. The yuan, as we have adopted this ink is printed under the influence of the money detector can be emerged in the authenticity.
3. Magnetic Ink
Magnetic ink for printing the first credit card number. As the magnetic card with easy to carry, quick settlement of the characteristics, will be widely used. Magnetic Ink for anti-counterfeiting packaging is mainly used in the packaging of a certain part of magnetic ink printing, can be detected with special instruments to form the secret anti-counterfeiting.
4. Fluorescent Ink
Fluorescent ink printed printing products colorful and decorative works well in the role of visible light and ultraviolet light, may issue sparkling fluorescent. Anti-counterfeiting packaging of the fluorescent ink can be its own deployment of security best results. Different formulations of different fluorescent effect can be drawn. Realistic in general difficult to counterfeit, thus forming a security secret.
Second, the security design of Screen Printing
The success of anti-counterfeiting packaging and printing products, packaging designers first need to mix a variety of anti-counterfeiting means of a full range of integrated design, so as to better and more safely serve security effectiveness.
1. The security design of packaging
Now alcohol and tobacco packaging and printing have adopted the screen printing method, can form ice-, refractive index, three-dimensional effect, and its essence is in the original electronic color separation negatives of screen time and when they make use of a special design method, used in security printing is a effective. Packaging security also can be used microform text, markings and other means of shelter for the design, is the best way to anti-counterfeiting markings.
2. Trademarks and paste the security design of bottle
The adoption of trademark anti-counterfeiting designs are made of laser holographic product labeling stamped iris being printed directly on the object to high-end luxury
Laser holographic version of the production of the iris is a highly technical, counterfeiting is not easy. Furthermore, is that we have technology and equipment it is impossible to replicate the same with the originals and color mark to. Posted security design of the bottle is best to use disposable adhesive paper (easy to shredding), makes it impossible to expose to take, but also now the most popular real-time screen printing stickers. .
3, anti-counterfeiting Screen Printing Process
With the high-tech development and people's demand for high-quality printing of packaging, packaging industry in recent years carried out technological innovation. Multi-color offset press, screen printer and other printing equipment with each other and use. The mutual penetration of a variety of printing process to make printing even more unpredictable and colorful.
1. Offset Printing, Screen Printing Portfolio Print
High-grade design of the packaging printing large blocks of color multi-color continuous tone and complex sequence of lines, motifs, etc., a single printing has brought some difficulties. If the use of offset printing, screen printing combined print that is better and better. Screen printing ink is characterized by thick uniform, the best printing large areas of the field blocks of color, using offset printing is characterized by the pressure level, the most suitable for printing four-color mesh lines to reconcile some of the complex. So avoid weaknesses, its role is very obvious. For some demanding and complex print, but also can be used offset printing, letterpress, screen printing and many other combination of printing processes. In short, the more complex printing processes, printing and more difficult the greater the security, the better.
2. Transition-color printing
Transition to color printing, also known as cross-color printing, using screen printing available on request, in the printed edition into the multi-hue of the ink, under the influence of the scraper so that part of the ink mixture and then printed on substrates. It can be a one-time printed on a variety of colors, and soft intermediate layer, can play a security role. If large areas of shading on the use of this technology and its security role will be more prominent.
3. Special luster security printing
Special gloss printing is more popular in recent years, packaging and printing sector, a new printing technology. Special luster is printed using this process printed materials, its surface gloss is different from ordinary ink, or printing paper reflected in the shiny effect. Printing process include: metallic luster printing, pearlescent printing, refractive index printing, fluorescent printing, variable gloss printing, laser holography iris print, crystal gloss printing, imitation metal etching print and matte printing. The special glossy printing process printed packaging features a colorful, magnificent, Ambilight, unpredictable, not only improved the product grade, an increase of product value, enriching the diversity of packaging products, but also has a certain degree of particularity and secretive, and, therefore, have the security role of the safer, at present most of the above process using a screen printing process.
4. Laser holography iris print
Iris print laser holography is used means of laser holography, in the shock chamber system, a template, through a certain pressure being transferred to a carrier, the product in the 45 ° light irradiation, can produce a colorful, unique and colorful effects and three-dimensional shape strong sense of three-dimensional images, by consumers of all ages. Currently used cold and hot stamping film coated two kinds of direct stamping process printing. It processes more complicated, it is very difficult, anti-counterfeiting excellent results.
Fourth, the security printing paper
Watermark security paper, printing paper of choice. Watermark paper is paper in the manufacturing process, using technical means to identify needs, design is done and in a paper in the. For example, in paper in the embedded metal wire, known as the safety line, in normal circumstances is not easy to see, only the front of light transmission in order to see. China's yuan mostly adopt the watermark paper printing. Now security printing which uses a special ink - waterproof ink printed tags, printed on coated paper to the ordinary, watermarks lifelike effect, mainly used in wine packaging.
5, anti-counterfeiting printing substrates
With the rapid development of high-tech, paper-making technology has continued to develop. The material can be produced under different light reflecting multi-colored pearlescent paper, laser film paper, laser-washed paper, washed light Yinlong, washed silver dragon, and other special security paper. The substrate is the best of the best security printing as a security printing material.
With the continuous development of the times, as well as scientific and technological progress, we believe that such a high-tech security printing technology will certainly play an increasingly important role. |
