Reasons for choosing u ink process for printing.UV process is a new process nowadays.

Compared with traditional processes, it has the advantage of printing one piece at a time

without plate making. UV process has good printability for most substrates. UV print has

clear dot, good tone reproduction, bright and bright ink, and high printing consistency.

At the same time, because the uv curing process is a photochemical reaction process,

both the ink layer and the varnish layer have the advantages of strong adhesion, durability,

water resistance, chemical corrosion resistance, wear resistance, aging resistance, etc.

Reasons for choosing u ink process for printing.The chemical substances in the uv ink form

a polymer three-dimensional network polymer through cross-linking reaction. Therefore,

the use of uv ink can make the ink layer of printed matter firm, fast dry and cross-linked.

Such ink layer has high abrasion resistance and chemical resistance. Many prints printed on

coated paper by uv ink for direct mail can withstand multiple folds and strong radiation during

laser printing again. Therefore, uv ink can be used for outer packaging printing that

requires wear resistance.

Reasons for choosing u ink process for printing.UV ink can only be dried under the irradiation of

ultraviolet light. Even if the ink is stored in the ink bucket for a long time, its performance will

remain stable and will not skin on the ink roller. Once the ink is irradiated by ultraviolet ray,

it can be dried instantly. Generally, it can be completely dried and fixed on the surface of

the substrate in 1/10S. Traditional thermosetting inks and sheet fed offset printing inks may

take several minutes or even days to completely dry, so printing live parts with uv curing inks

has a short delivery time, comparable to flexographic printing and gravure printing, greatly

improving the production efficiency of printing.
