What are the difficulties in the printing process of UV ink?

 

 

 

Compared with traditional ink printing, UV ink ultraviolet printing does have great advantages, but the popularity of applications also faces some problems to solve and improve.

 

 

 

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.

 

 

 

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. Like the time above, the ink-jet coatings suitable for ultraviolet printing ink are mainly used for non-absorptive printing materials. Different printing materials, the preparation of UV ink is different. Therefore, there must be a wide range of adaptability to ensure the required printing quality. Despite the above problems in ultraviolet printing, with the maturity of related technology and its rapid development of popularization and application, ultraviolet printing will be more widely used and popularized in the near future.
