In the past, ultraviolet light sources used in the printing industry generally used light sources such as high-pressure mercury lamps and metal halide lamps. Due to the enlargement of lamps and power supply devices, users are worried about the damage and use of printing machines and substrates due to large power consumption and high heat generation. Problems such as ozone generation in the process. With the advent of UV light curing technology, due to its environmentally friendly characteristics, environmental pollution is relatively small compared to the solvent type, and the operating cost is comparable to or even lower than the solvent type, so it is getting more and more attention. The survey results show that the market share of LED-UV flatbed printers quickly reached 11.7%, while the market share of solvent-based wide format inkjet printers has fallen to 33.6%.

UV light curing technology is a new technology for green industry. It was rated as "5E" industrial technology by the North American Radiation Curing Committee. It fully demonstrates the characteristics of the technology, that is, high efficiency, energy saving, environmentally friendly, economical, Wide adaptability. At present, the commonly used UV curing lamps on the market are generally mercury arc lamps, or mercury lamps for short. The UV mercury lamps have a limited service life and large energy consumption, but the energy used is not high. In addition, although UV mercury lamps are relatively Solvent-based inks are environmentally friendly and environmentally friendly due to the absence of VOC emissions, but UV mercury lamps also have some hidden pollution, such as the easy production of ozone, which has a greater impact on health.

In 2008, the LED curing technology debuted at the Drupa exhibition, which aroused widespread concern in the industry. Many printers and ink manufacturers showed their own this technology. LED curing is one of the most attractive technologies in the field of energy curing. This technology is becoming more and more popular due to its energy-saving, high-efficiency, economic, environmental protection, wide adaptability, UV advantages, cold light source curing without infrared radiation, and no ozone emission. Favored by people. At present, the market demand for LED UV technology is very strong. Digital printing has become the largest market for this technology, in which the inkjet field has the most innovations, and the advantages of LED UV can meet the needs of this field. Based on years of experience in the inkjet industry and close contact with the market, Hongsheng Digital, together with a large number of domestic and foreign professional exhibition information and information collection and refinement of professional academic exchanges, keenly aware of the market opportunities, started early The research and development of UV ink, and directly positioned in the development of LED UV ink.
