Offset offset printing is mainly used for the printing of paper-based materials. Printing on plastic film has many limitations. Sheet-fed offset presses can be changed in print format and are flexible. At present, most web offset presses have a fixed print format. Its application is limited. With the development of technology, web offset presses are also constantly improving. Now we have successfully developed a web offset press that can change the printing format. At the same time, we have successfully developed a seamless roller web offset press. The printing cylinder of this web offset printing machine is seamless and in this respect has been the same as a web gravure printing machine.
Offset presses continue to improve on printing capabilities. The corrugated board can be printed with improved and retrofitted parts. UV printers can be printed with improved UV dryers. The above improvements continue to expand the use of offset presses in the field of packaging and printing. Offset printing inks will soon be put into practical use. Offset printing here is another step.
Gravure Gravure, ink full three-dimensional, in a variety of printing methods, the print quality is the best. And the printing quality is stable. The plate has a long life. Suitable for mass printing. Gravure prints extremely thin materials such as plastic films. However, gravure platemaking is complicated and expensive, and its benzene-containing ink pollutes the environment. These two issues have affected the development of gravure. In particular, the reduction of a large number of large-scale prints, the short version also requires a large number of low-cost prints, so that gravure will continue to lose the market.
The main advantages of flexo flexo are:
1, the device structure is simple, easy to form a production line. The flexo printer is the simplest structure in the three printing equipments of offset printing, concave printing and flexo printing. As a result, the price of flexo presses is relatively low, and printers invest less in equipment. At the same time, due to the simple equipment, easy operation and maintenance. At present, the vast majority of flexographic printing presses are connected to processing technologies such as Tang Jin, glazing, cutting, slitting, die cutting, indentation, punching, and windowing to form a production line. Greatly increase labor productivity.
2, a wide range of applications and substrates. Flexo can print almost all prints and use all substrates. In particular, corrugated printing in packaging printing has its own unique features.
3, extensive use of water-based ink. Among the three printing methods of offset printing, gravure printing and flexo printing, only flexographic printing currently uses water-based inks. Non-toxic, non-polluting, favorable for environmental protection, especially suitable for packaging and printing.
4, the lower cost. The low cost of flexo printing has formed a broad consensus in foreign countries.
