Problems solved by technology

[0002] With the rapid development of the communication field, electronic products have become an indispensable entertainment and communication tool for people. Electronic product covers are also full of tricks, but traditional electronic product covers are mostly printed with ordinary solvent-based inks. These electronic products The brightness of the cover plate is too poor, the color resistance is not strong, it is easy to age, and it is not conducive to environmental protection, so it cannot be recycled. UV ink is ultraviolet curing ink, which refers to the use of ultraviolet light of different wavelengths and energies under ultraviolet irradiation. The monomer in the ink binder is polymerized into a polymer to make the ink film-forming and drying ink. This kind of UV ink has a significant development prospect from the perspective of environmental protection, quality, color and technological development.
