Technical characteristics of new UV-LES inks and waterless offset inks

The development of UV-LES inks came from the cost of disasters. The accident in the Fukushima earthquake in Japan caused extreme energy shortages in Japan, which greatly promoted the development of UV-LES inks. Like UV-LED inks, UV-LES inks also have the characteristics of energy saving and emission reduction. Compared with ordinary UV inks, they can save more than 60% of curing power, do not produce ozone, and are in the process of equipment modification and operation. UV curing systems are closer and more acceptable, The involvement of printing equipment suppliers is also deeper. For example, Mitsubishi's eco UV curing system and Komori 's H-UV curing system are quite mature. Devices using UV-LES inks are quite common in Japan, and some printing companies in the country have adopted such equipment and inks.

The waterless offset printing ink technology starts from the oily waterless offset printing ink, and then gradually develops into UV waterless offset printing ink. Compared with the traditional waterless offset printing ink, the waterless offset printing ink does not involve ink and water balance in the printing process, and the ink transfer mainly passes. The temperature of the rubber roller is controlled to achieve a certain degree, which solves the problem that the printing enterprise discharges a large amount of sewage to a certain extent. At present, the biggest bottleneck in the development of waterless offset printing ink technology is that there are very few ink manufacturers capable of producing high quality waterless offset printing inks in China. Only Hangzhou, DIC, Tianjin Dongyang and other companies, in addition, waterless offset printing requirements for printing environment and control It is quite high, especially for the stability of the printing environment, which affects its promotion in domestic printing companies. However, in the long run, the popularity and application of waterless offset inks is the trend of the times.
