Compared with traditional ink printing, the printing process of UV printer does occupy a greater advantage, but there are still some problems to be solved and improved in popularization and application.

1. Price of UV printer ink

Although UV ink has the advantages of instant curing and good conjunctival performance, it is relatively expensive. At the same time, special UV blanket and UV ink roller must be used, which greatly increases the product cost.

2. Adhesion of UV printer ink

During the curing of UV ink, the internal components are crosslinked and polymerized, and the instantaneous change of volume produces large internal stress, which affects the adhesion of the ink to the substrate.

3. UV printer ink suitable fountain solution

UV ink is mainly used for non absorbent printing materials, and the ink configuration of different printing materials is also different.
