What are the advantages of uv ink in the offset printing industry?

   uv ink dries fast. The uv ink is cured immediately after being irradiated by the line,

and its drying speed is usually 0.3-2 seconds, so it is suitable for high-speed printing

or immediately post-processing the printed matter, which can shorten the operation

cycle and improve labor productivity. Compared with gravure printing, uv ink does

not need to use organic solvents, which can save oil resources, reduce damage to

our living environment, and save the cost of air purification. The working environment

and health issues of workers have been improved.

   Ink consumption is small. For the same printed matter using ink printing, uv ink

generally only needs to use 1/3 or 1/2 of the amount of infrared drying ink to achieve

the same printing effect. Compared with hot air drying or infrared drying, it has

the characteristics of low energy consumption, and at the same time, the temperature

rise of the printed matter surface after being irradiated by light is small. The uv ink

will not cure before the ultraviolet light is irradiated, which can reduce the time for

cleaning the printing plate and the blanket. Inks are not limited by the type of substrate,

and can be printed on cheap paper or non-absorbent materials such as plastics,

metals, ceramics, and glass.

   The floor area is small, the equipment is simple, and the device only needs to be

equipped with an ultraviolet lamp, and does not need a long drying tunnel like an

infrared device. Because the ink is cured by polymerization after being irradiated by

ultraviolet rays, the entire ink layer is a network cross-linked structure, the ink film is dense,

hard, friction-resistant, scratch-resistant, and the printed product is bright and

has a good texture.
