The Application of UV ink
UV ink has been widely used in offset printing, flexo printing, gravure printing, screen printing and inkjet printing due to its advantages of instant curing, low energy consumption, low pollution and excellent printing adaptability.
Offset UV ink occupies a considerable proportion in the application of UV ink, including offset ink, offset toner ink, offset varnish, offset grinding ink, offset pearlescent ink, etc. It is widely used in packaging printing, book cover printing, CD cover printing and high quality, large quantities of label printing. Offset printing UV ink has the following characteristics. The curing speed is fast.
Under UV irradiation, offset UV ink can be solidified in seconds. Packaging printing often requires a large area of field printing, and requires a higher printing density, so it is necessary to increase the amount of ink, then the drying problem becomes very important, if the ink drying is not good, it often affects the pot effectiveness, and the use of offset UV ink, the topic will become canal. Prevent ink crust.
Offset UV ink can prevent the ink from forming, and relieves the worry of printing ink when the offset press stops. All kinds of substrates have superior power of attachment. Offset UV ink curing without penetration and seepage, can be printed on non-receptive substrate, such as card, this is a popular offset ink can not be involved in the field. Improve printing environment.
Because offset UV ink does not need powder spraying in printing, the printing environment has been improved and the troubles caused by powder spraying for post-press processing, such as polishing and film coating, have been avoided.
