1. Screen printing UV ink
The advantage of UV ink in screen printing is very obvious, because it can only be cured under UV light, it will not produce a headache blocking problem on the screen, and the curing speed is fast, and the troubled wire is solved well. The net printing industry has long been incompatible with the speed of ink drying and blocking.
The thicker ink layer of the screen printing material is difficult to dry. If there is no drying device, it is difficult for the printing material to accumulate, and it is very difficult to achieve high-speed printing. With UV ink, all this is solved. For example, in the printing of optical discs, all UV inks are used to improve the production efficiency.
2. Offset UV ink
UV inks can be divided into two major categories from use: UV printing inks and UV printed circuit board inks. Currently, UV printing inks for the printing industry are used in various printing fields such as offset printing, letter printing (including flexographic printing), gravure printing, screen printing, and inkjet printing. UV printing circuit board inks are mainly used in circuit boards in the electronics industry. (PCB) printing.
3. Letterpress UV ink
Toppan printing UV ink is mainly used for label printing, but also for packaging printing, such as hose printing.
In flexo printing, especially in narrow flexographic printing, people pay more attention to less downtime, more friction resistance, and better print quality. With UV ink printing product network with high resolution, small dot gain, bright ink, compared with water-based ink printing to improve a grade. UV inks have broad prospects for development.
At present, most flexographic printing presses are equipped with UV curing devices, and there are many types.
4. Gravure printing UV ink
In the field of gravure printing, UV inks have been selectively used, but the technology and cost have been correspondingly increased. With the growing demand for environmental protection and the increasingly stringent requirements for the safety of packaging printed materials, especially food packaging, UV inks will become a trend in the development of gravure printing inks.
