Combined printing and anti-counterfeiting label technology

The production of anti-counterfeiting labels is closely related to combination printing. Whether it is off-line combination printing or on-line combination printing, gravure printing, offset printing, flexo printing, silk screen printing, embossing, variable information, holographic hot stamping, laser aluminum foil paper and other technologies have played an important role. The mutual penetration of a variety of printing equipment and processes makes printing graphics more unpredictable and colorful. The use of combined printing technology label products also set up many obstacles for counterfeiters, to achieve the purpose of anti-counterfeiting.

Combined printing and anti-counterfeiting label technology

Anti-counterfeiting technology is to achieve the purpose of anti-counterfeiting, in a certain range can accurately identify the authenticity is not easy to be imitated and copied technology. It has its own technical threshold, scale threshold, equipment threshold, process threshold and other barriers, difficult to be copied and imitated. From the point of view of printing technology, anti-counterfeiting technology mainly includes engraving plate making, computer design plate pattern, gravure printing, rainbow printing, pattern docking, double-sided printing technology, multi-color wiring printing, multi-color overprinting, microfilm printing, material texture, refractive latent image, invisible image and image mixing printing, etc. With the in-depth development of anti-counterfeiting technology, some new forms of anti-counterfeiting technology, such as two-dimensional code, RFID and other anti-counterfeiting technology are also emerging, effectively meet the growing market demand.

Generally speaking, it is not easy to print high-quality printed matter with a single printing method, and the anti-counterfeiting effect is limited. In order to achieve the appropriate anti-counterfeiting effect, a variety of anti-counterfeiting technologies are often applied in the actual production process. Therefore, the use of a variety of printing processes and anti-counterfeiting means of the combination of printing can produce high-grade label printing and process requirements of higher and more complex anti-counterfeiting label printing, so as to achieve the purpose of anti-counterfeiting. It can be seen that the birth of combined printing is the inevitable product of the development of anti-counterfeiting technology to a certain stage.

Anti-counterfeiting effect of combined printing

General high-grade label printing design has a large area of color blocks, multi-color sequential continuous adjustment of the picture and complex lines, patterns, etc., to a single printing means has brought a certain degree of difficulty, and the combination of printing is a good solution to this problem. It can give full play to the advantages of various printing methods and avoid disadvantages. Such as the use of flexo printing large-area field, offset printing four-color continuous and complex line parts, gravure printing metal color, silk screen printing convex and scratch layer, so the effect is very obvious.

In short, the more complex the printing process, the more difficult the printing of the label print, the better the anti-counterfeiting effect. The combination of gravure printing, offset printing, flexo printing, silk screen printing, cold ironing and even blanching is a kind of anti-counterfeiting combination. The realized label products combine these processes, adopt some unique designs, add variable information and two-dimensional codes, and combine ink anti-counterfeiting label technology and holographic anti-counterfeiting technology to realize the uniqueness of the products and can be mass-produced.

Process advantages of combined printing

In combination printing, it is often applied to a variety of printing technologies and processes. Therefore, the combination of printing also set a variety of printing technology and process strengths. In general, combination printing often combines the advantages of gravure printing, offset printing, flexographic printing and screen printing.

The advantages of various printing methods are as follows. Gravure printing has the advantages of high production efficiency, good hue consistency, and good adaptability of printing materials. It has excellent performance in field, spot color, gold (silver) ink printing, etc., and can meet the strict requirements of packaging and printing quality. Offset printing, on the other hand, has a set of standardized and data-based methods for the reproduction of printed matter with rich gradation levels. Flexographic printing, due to the short ink path, printing no color difference, for the field of color block printing has an unparalleled advantage. In particular, with the rapid development of flexo printing supply chain such as plates, plate making equipment, printing machines, etc., the quality of flexo printing has made rapid progress, and the level of reproducibility is good, which can meet higher printing requirements. The importance of anti-counterfeiting label printing in labels and packaging is getting higher and higher. And screen printing, can produce thick ink layer, create concave and convex, matte, refraction, ice flowers, wrinkles and other effects, thus greatly improving the visual effect of printed matter.

Application of Combined Printing in Labels

Combination printing is widely used in label printing in China. In order to ensure the safety performance of the label and prevent the label from being illegally copied, in actual production, offset printing, gravure printing, embossing, silk screen printing, holographic hot stamping and other methods are generally used to ensure the safety of the anti-counterfeiting label. For example, China's instant sports lottery, the lottery adopts a variety of printing methods such as front and back printing, anti-transmission printing, microtext, connection variable data printing, peeling varnish printing, scratch ink printing, color patterns and glazing, etc. The connection process is complicated and plays a good anti-counterfeiting role. Another example is the label printing of daily chemicals and bath products, which organically combines embossing, flexo printing, silk screen printing, ink anti-counterfeiting, texture anti-counterfeiting and two-dimensional code anti-counterfeiting technologies online, increasing production efficiency and improving product functions and anti-counterfeiting effects. Alcohol anti-counterfeiting labels use off-line technology, the embossing, flexo, silk screen, variable information, hot, plate and miniature printing anti-counterfeiting technology together, so that the product has a very good anti-counterfeiting effect!

In short, combination printing not only gives full play to the characteristics of several printing methods, but also can learn from each other to improve the grade and quality of printed matter, combined with various anti-counterfeiting technologies, so that the printed labels and printed matter integrate various anti-counterfeiting technologies, protecting the corporate brand, protecting the market, and protecting the legitimate rights and interests of consumers! The pioneers who use the combined printing process will also get a good profit return.
