With the emergence of new technology and new products, will further expand the packaging market. In this sense, the packaging printing is never fading printing industry. There are a lot of packaging printing printing, printing more commonly used are the following:
Packaging printing methods commonly used:
Packaging printing printing: gravure printing commonly used
Gravure printing, full color stereoscopic, in a variety of printing, the printing quality is the best. And print quality is stable. Printing plate life. Suitable for large quantities of printing. Gravure printing the thin material, such as plastic film. But the high price of the gravure complex, benzene ink environmental pollution. These two problems affecting the development of gravure printing. Especially the reduction of mass printing, the short version also requires cheap copies of a large increase, the gravure losing market.
Packaging printing common: flexo
Flexo printing is a kind of direct printing, printing plate image projection has elasticity.
1, the structure of the device is simple, easy to form a production line. In offset printing, flexo printing, three concave printing equipment in the flexo printing machine is the most simple structure. Therefore, flexo printing machine price is relatively low, less investment in equipment in printing enterprises. At the same time, because of the simple equipment, easy to use, easy maintenance. At present, the vast majority of flexo printing machine, and such as Jin Tang, polishing, cutting, cutting, die-cutting, indentation, punching, windows, and other processing line connecting to form a production line. Greatly improve labor productivity.
2, application scope and wide range of substrates. Flexo printing almost all and use all of the substrate. Especially in the packaging and printing of corrugated paper printing has a unique place.
3, wide use of water-based ink. The offset and gravure printing, flexo printing in three, only the currently widely used in water-based ink flexo printing. Non toxic and non polluting, favorable for the protection of the environment, particularly suitable for packaging printing.
4, low cost. Flexo printing of low cost in foreign countries has formed a broad consensus.
