Everyone must be familiar with China's "The Four Great Inventions", especially papermaking, which has a great impact on humans. So far, there have been papers all around, and paper products are no substitute for market activities.

        There are many paper products on the market that are UV prints. Currently, the usual glazing methods include offset glazing, gravure glazing, and screen printing. Among them, screen printing is a partial UV glazing method adopted by most printing houses. The advantages of screen printing are many: the glazing effect is various, the thickness of the varnish layer can be adjusted, and the covering power and the stereoscopic effect are strong, while highlighting the product characteristics, Enhanced visuals with high flexibility and wide applicability

        The UV LED light source has been used in the paper UV glazing, ensuring print quality in place of conventional mercury lamps. In the lottery issued in China, the “scratch music” is typically applied to the UV partial glazing technology. The glazing treatment is applied to the local position of the scratching area to ensure the waterproof and moisture-proof of the lottery area, and the wear-resistant safety to ensure the stability of the printed graphic characters in the lottery area. Sex, in addition, it can be ensured that the masking ink has releasability, and then the screen is shielded from the ink at the glazing portion.

        In the UV glazing process, the choice of UV light source and UV varnish is very important. The UV LED light source can completely replace the traditional mercury lamp in the curing of varnish, especially avoiding the bending deformation of paper due to high temperature during UV glazing. Moreover, the use of UV LED light source saves a lot of electric energy, saves a lot of cost compared with the traditional mercury lamp, and wins more cost-effectiveness for the enterprise.

        The replacement of traditional UV mercury lamps by UVLEDs is definitely a trend, but there is still a way to go. The combination of UVLED cold light sources and UVLED inks has become the decisive factor in the progress of UVLEDs replacing UV mercury lamps.

        In the end, is the UVLED light source driving the UVLED ink, or is the UVLED ink driving the UVLED cold light source? We believe that this does not have to go deeper, the two must be complementary, although UVLED ink can be cured with UVLED cold light source, can also be cured with UV mercury lamp, but for the long-term development of the enterprise, the use of UVLED curing can save a lot of cost for the enterprise, While improving production efficiency, it will contribute to environmental protection and sustainable development of society.
