The reason why the flexographic printing machine develops at a constant speed is that in addition to the technological breakthroughs in the sheet and ink, its own characteristics are an important reason for attracting users.
1. The machine has a simple structure, so it is easy to operate and easy to maintain. The price of a flexo press with the same function is about 30-50% of an offset or gravure press.
2. The causative material has strong adaptability, and satisfactory printing results can be obtained from 0.22mm plastic film to 10mm corrugated cardboard.
3. The embossing force is small, about 19.6-39.2N/square centimeter, especially for the printing of substrates such as corrugated paper that cannot withstand excessive pressure.
4. The printing cost is low, mainly because the machine price is cheap, the plate making cost is low, the paper breakage rate during the printing process is low, and the production cost is 30-50% cheaper than the gravure printing.
5. The quality of the printed products is good. The use of anilox roller short ink path inking system not only simplifies the structure of the inking system, but also enables quantitative control of film thickness. The breakthrough in high-performance photosensitive resin plate technology has greatly improved the resolution of the printing plate and the reproducibility of the dots (up to 1-95%). Flexo printing can achieve 300 lines/in color level draft printing, and the printing effect is comparable to offset printing and gravure printing.
