As the traditional light-curing material, UV light-curing inks are variable and easy to be developed. This October, blue LED was awarded Nobel prize and our R&D members were greatly inspired by its potential value.
In nearly two-month tests on blue light sources, we were trying to equip the blue LED with more options in its ink colors and functions, such as the flexible ink. So technically speaking, our R&D members think that blue light has more chances than UV light in the future.
By the way, our R&D members are big fans of emerging technologies. They are always crazy for it and trying to apply these new techs to create some fancy gadgets.
