Development prospects of packaging box printing:
As an important and traditional carrier of information, the production of paper has been prosperous for a long time and is increasingly closely related to printing technology. With the development of economy and the progress of technology, new requirements are constantly 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 letterpress printing to offset printing, and from letterpress printing paper production to offset printing paper production. Now, the printing of printed matter in China, the use of letterpress printing, has been very few, very few, letterpress printing is almost all replaced by offset printing. Although the Chinese paper industry still regards letterpress printing paper as the key product of industry statistics, the actual production is no longer the past letterpress printing paper, most of which are offset book and periodical paper.
The following are the printing methods that can be seen everywhere:
Box offset printing
Flexo - The main advantages of flexo printing are:
1, equipment structure is simple, easy to form a production line. In offset printing, concave, flexographic printing three printing equipment flexographic printing machine is the most simple structure. Therefore, the price of flexo printing machines is relatively low, and the equipment investment of printing enterprises is small. At the same time, because the equipment is simple, easy to use and operate, easy to maintain. At present, the vast majority of flexo printing machines are connected with processing processes such as tangjin, glazing, cutting, splaying, die-cutting, indentation, punching, window opening and so on to form production lines. Greatly increase labor productivity.
2. Wide range of applications and substrates. Flexo printing can print almost all printed matter and use all substrates. Especially in the packaging printing of corrugated paper printing has a unique place.
3, widely used water-based ink. Of the three printing methods of offset printing, gravure printing and flexo printing, only flexo printing is currently widely used water-based ink. Non-toxic and pollution-free, favorable for protecting the environment, especially suitable for packaging and printing.
4, low cost. Flexo printing cost low in foreign countries has formed a broad consensus.
Box gravure
Gravure printing, the ink color is full and three-dimensional, and the printing quality is the best in various printing methods. And the printing quality is stable. Long plate life. Suitable for mass printing. Gravure printing can print extremely thin materials, such as plastic film. However, gravure plate making is complex and expensive, and its benzene inks pollute the environment. These two problems have affected the development of gravure printing. In particular, the reduction of a large number of printing pieces, and the large increase in the number of printing pieces requiring low prices at the same time, make gravure printing continue to lose the market.
