Although uv ink is an environment-friendly ink, it will inevitably produce a pungent

smell and bring a small amount of harm. It should be noted that the cheaper the uv ink is,

the more toxic and harmful it is. Cause: The pungent smell of uv ink is first of all its own raw

materials, which are slowly emitted under certain conditions; Secondly, after uv ink

curing, raw materials such as initiators and resins will be cracked to produce aldehyde

and sulfur irritating gases. At this stage, most of the irritating smell of uv printing is mainly

from the volatile matter released before and after the uv ink itself is cured.

Methods of eliminating the pungent smell of uv ink.There are hundreds of initiators in

use in the market, but the initiation efficiency, price, color depth and scope of use vary greatly.

At present, most domestic printing enterprises use 907 initiator in uv ink. This kind of initiator

has moderate price and high initiation efficiency, but it will crack out unpleasant "methylthio"

after curing. In order to reduce the odor problem of initiators, these initiators can not be used.

Use some high-grade initiators, of course, the cost of printing ink will increase accordingly.

It can be said that the selection of better low odor uv ink is one of the keys to solve

the problem of irritating smell.
