Compared with the traditional ink printing, UV printing does have a big advantage, but also face to popularize and apply some must solve the problem and improve. 

The price of 1, UV printing ink Although UV ink has a good property of transient solidification and conjunctival advantages, but the price is relatively expensive, at the same time, you have to use special UV rubber cloth and UV ink roller, greatly improving the product cost. 

2, UV printing ink adhesion of UV ink in curing, internal components by crosslinking polymerization, instantaneous changes produce the internal stress of large volume, affect the ink adhesion to substrates. Although the surface treatment of substrates or modification, can improve this problem, but the fundamental solution is to seek and develop good adsorption, shrinkage stress is small, cheap UV ink. 

3, UV
