Most of the contemporary wine boxes are bright and shiny, which is mainly due to the development and innovation of printing technology . Wine box printing is a collection of various printing processes. It has the advantages of traditional offset printing , gravure printing, screen printing and flexo printing, and also incorporates some new printing technologies. At the same time, these printing technologies are constantly evolving and improving.
Screen printing process
The screen printing process has many advantages such as thick ink collecting layer, rich graphic and graphic layers, strong stereoscopic effect and wide range of printing materials. It is widely used in high-end wine box printing. In particular, the use of UV screen printing ink for printing, not only can show special effects such as frosting, refraction, ice, wrinkles on the wine box, but also can meet environmental protection requirements, in line with the current industry development.
2. Special gloss printing process
The special gloss printing process is a new technology popular in the packaging and printing industry in recent years, and has also been applied in the field of wine box printing. The special gloss printing process mainly includes metal gloss printing, pearl printing, pearl gloss printing, refractive printing, matte printing and the like.
3. Anti-counterfeiting ink printing process
Anti-counterfeiting ink printing is an important branch of anti-counterfeiting technology for wine packaging . It has the advantages of simple operation, low cost, good concealment, bright colors, convenient inspection and strong reproducibility. It is worth noting that in order to obtain the desired anti-counterfeiting effect by this printing method, it is necessary to fully consider the printing method, the selection of printing equipment , the processing of printed products, the use of anti-counterfeiting ink, etc., and the level is very high.
4. Multi-color serial printing process
Multi-color serial printing is also called "cross-color printing" and "rainbow printing", which is mostly achieved by the embossing process. Before the printing starts, a plurality of separators are placed in the ink tank, and then inks of different hue are respectively placed in different partitions according to printing requirements, and the ink in the adjacent partitions is used in the string action of the ink jet rollers during printing. Mixing occurs and is transferred to the surface of the plate. With this printing process, multiple colors can be printed at one time, and the intermediate transition is soft. In addition, since it is difficult to see traces of the ink tank partition on the surface of the printed product by the naked eye, the printing method can also play a certain anti-counterfeiting effect, especially in large-area shading printing, and the anti-counterfeiting effect is more prominent.
