Cake box printing can be seen everywhere

Cake box printing can be seen everywhere. The development prospect of packaging box printing: as an important and traditional information carrier, the production of paper has been prosperous, and more and more closely related to printing technology. With the development of economy and technology, new requirements have been put forward for the variety, quality and performance of paper. In the 1980s, China's printing industry and China's paper industry jointly completed the process of transforming from relief printing to offset printing, and from relief printing paper production to offset printing paper production. At present, the printing of China's printed matter, using relief printing, is very few, very few, relief printing is almost completely replaced by offset printing. Although China's paper industry still regards relief printing paper as the key product of industry statistics, what it actually produces is not the past relief printing paper, most of which are offset printing books and periodicals. The following are the printing methods that can be seen everywhere in packaging box printing: packaging box offset printing is mainly used for the printing of paper-based materials. Sheet fed offset press printing format can be changed, more flexible. At present, the printing format of most web offset presses is fixed. Its application is limited. With the development of technology, web offset press is constantly improving. Now we have developed a web offset press which can change the printing format. At the same time, we have successfully developed a web offset press with seamless rollers. The printing cylinder of the web offset press is seamless, which is the same as the web gravure press. The offset press is still improving its printing function. After improvement and adding some parts, corrugated board can be printed. After improvement and installation of UV drying device, UV printing can be printed. The above improvements continue to expand the use of offset press in the field of packaging and printing. Water based ink for offset printing will soon be put into practical use. Here offset printing is another step. The main advantages of flexographic printing are: 1. The equipment structure is simple and easy to form a production line. Among the three major printing equipments of offset, concave and flexo printing, flexo printing machine has the simplest structure. Therefore, the price of flexo press is relatively low, and the equipment investment of printing enterprises is less. At the same time, because the equipment is simple, easy to operate, easy to maintain. At present, the vast majority of flexo printing machines, such as soup gold, glazing, cutting, slitting, die cutting, indentation, drilling, windowing and other processing technology line, forming a production line. Greatly improve labor productivity. 2. Wide range of applications and substrate. Flexo printing can print almost all the printed matter and use all the substrate. Especially in the packaging printing of corrugated printing has a unique place. 3. Water based ink is widely used. Water based ink is widely used in offset printing, gravure printing and flexo printing. It is non-toxic and pollution-free, which is good for environmental protection, especially suitable for packaging and printing. 4. The cost is low. Flexo printing cost is low, in foreign countries has formed a broad consensus. Gravure printing of packaging box, with full ink color and three-dimensional feeling, printing quality is the best among all kinds of printing methods. And the printing quality is stable. Plate life is long. Suitable for mass printing. Gravure printing can print extremely thin materials, such as plastic film. However, gravure plate complex, high price, benzene ink pollution. These two problems affect the development of gravure printing. In particular, the reduction of a large number of prints, short version at the same time requires a large increase in low-cost prints, so that gravure printing continues to lose market.
