UV inks have been widely used in offset printing, flexo printing, gravure printing, screen printing and inkjet printing due to their instant cure, low energy consumption, low contamination, and good printability.
Offset UV inks occupy a considerable proportion in the application of UV inks, including offset inks (paper, plastic, metal, etc.), offset inks, offset lacquers, offset matte inks, and offset pearl inks. It is widely used in packaging printing, book cover printing, CD jacket printing, and high-quality, high-volume label printing and other fields. Offset UV inks have the following features.
(1) Fast curing. Under ultraviolet light, UV offset inks cure in seconds. Packaging printing often requires printing on a large area in the field, and requires a higher printing density, so the ink volume has to be increased. At this time, the drying problem becomes very important. If the ink is not dried well, it often affects the production efficiency. Offset UV ink, this problem will be solved.
(2) Prevent ink crusting. Offset UV inks can prevent ink skinning and relieve the worry of ink skinning when the offset press stops.
(3) It has good adhesion to various types of substrates. Offset UV inks do not penetrate when cured and can be printed on non-absorbent substrates such as cards, which is an area where ordinary offset inks cannot be covered.
(4) Improve the printing environment. Since the offset UV ink does not need to be powdered during printing, the printing environment has been improved, and the troubles caused by powder spraying to the post-press processing are avoided, such as light and film coating.
