The production of anti-counterfeit labels is closely related to combined printing. Whether it is offline combined printing or online combined printing, gravure, offset printing, flexo printing, silk printing, embossing, variable information, holographic hot stamping, and laser aluminum foil paper have played an important role effect. The mutual penetration of various printing equipment and processes makes the printed graphics more unpredictable and colorful. And the use of combined printing technology label products also set up numerous obstacles for counterfeiters, to achieve the purpose of anti-counterfeiting.
Anti-counterfeiting technology is adopted to achieve the purpose of anti-counterfeiting. It can accurately identify the authenticity within a certain range and is not easy to be copied and copied. It has barriers such as technology threshold, scale threshold, equipment threshold, and technology threshold, which are difficult to be copied and copied. From the perspective of printing technology alone, anti-counterfeiting technologies mainly include engraving, computer-designed patterns, gravure printing, rainbow printing, pattern matching, double-sided printing technology, multi-color wiring printing, multi-color overprinting, micro-printing, materials Texture, latent latent images, invisible images and image scramble printing. 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 technologies, have been continuously produced, which has effectively met 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 a suitable anti-counterfeiting effect, many anti-counterfeiting technologies are often applied in the actual production process. Therefore, the combination printing using multiple printing processes and anti-counterfeiting methods can produce high-end label printed matter and anti-counterfeit label printed matter with higher and more complicated process requirements, thereby achieving the purpose of anti-counterfeiting. It can be seen that the birth of combination printing is an inevitable product of the development of anti-counterfeiting technology to a certain stage.
