Offset UV varnish printing ink with mirror surface effect and preparation method of offset UV varnish printing ink

The invention relates to an offset UV varnish printing ink with mirror surface effect and a preparation method of the offset UV varnish printing ink. The offset UV varnish printing ink with mirror surface effect is characterized by comprising the following compositions in percentage by weight: 19%-23% of standard bisphenol A epoxy acrylate, 61%-65% of dipropylene glycol diacrylate, 3%-7% of p-benzoyl polyethylene glycol benzoate, and 9%-13% of reactive tertiary amine. According to the invention, the offset UV varnish printing ink with mirror surface effect has good levelness and transparency without addition of auxiliaries such as a leveling agent and a defoaming agent, the offset and polished product has a mirror-like effect, and the smooth, level and transparent effects of a mirror can be simulated on a paper package by means of printing. No reaction auxiliaries are added in the printing ink, so that the curing resistance can be reduced, and the influence on the transparency and compatibility of the printing ink can be reduced. The printing ink is less in side reaction in curing reaction, low in migration rate and volatility, thus having high environment-friendly property; and the Vocs smell can completely achieve the national standard requirement.
