What problems may be encountered in ink irradiation by UV li

Compared with traditional ink printing, UV ink ultraviolet printing does have great advantages, but the popularity of applications is also facing some problems to solve and improve. The same time as above

 

1. Although the price of UV ink has the advantages of instant curing and conjunctival film performance, it is relatively expensive, but special UV blanket and UV ink roller must also be used, which greatly increases the cost of products. The same time as above

 

2. The adhesion of ultraviolet ink in curing process, the internal components of cross-linking polymerization, and the internal stress with large volume instantaneous change affect the adhesion of ink to printing materials. Although surface treatment or modification can improve the problem, the basic solution is to find and develop good adsorption, shrinkage stress is small, cheap UV ink. The ink-jet coating suitable for ultraviolet printing ink is mainly used for non-absorptive printing materials, and the preparation of UV ink is different for different printing materials.
