Large-on-line gravure UV reverse ink on gold and silver card paper material

Abstract

The invention relates to the field of polymer materials, and discloses a large-on-line gravure UV reverse ink on a gold and silver card paper material, which comprises, by weight, the following components: 10-25% of fatty acid-modified epoxy acrylate; 5%-15% of aliphatic urethane acrylate; 10%-20% of trimethylolpropane triacrylate; 30%-45% of dipropylene glycol diacrylate; 4%-6% of hydrogen abstraction photoinitiator, 1%-3% of cleavage photoinitiator; 10%-15% of amine initiator; 0.1%-0.5% of polymerization inhibitor; 0.1%-3.5% of auxiliary agent. The invention also discloses a preparation method and an application method thereof. The UV reverse ink has the advantages of good reverse effect, good adhesive force and good fluidity, and can meet the requirements of high-speed printing and decorating ink.

Description

technical field [0001] The invention relates to the field of macromolecule materials, in particular to large-line in-line gravure UV reverse ink for gold and silver cardboard materials and its preparation method and application. Background technique [0002] In the past, if processing enterprises wanted to achieve the effect of "partially glossy and partly matte" on the surface of the same label, they generally needed to use various printing methods such as offset printing, screen printing, or flexo printing. The production efficiency was not high, and the registration was also difficult. difficulty. In addition, in order to achieve precise spot varnish effects, there may be a high rejection rate. But now this situation has improved, and a "reverse glazing process" is popular in the market, which is a process in which typical bright and matte effects are formed on a label at the same time. [0003] The working principle of the reverse glazing process is to use the "mutual ...

AI Technical Summary

Problems solved by technology

[0004] The reverse inks on the market are mainly offset printing. There are basically no reverse inks for large-scale gravure printing on the market at present, and the offset printing efficiency is not high enough, and the reproducibility of the reverse effect is not good; especially for large-volume web printing, the background color It is gravure printing ink, and then reverse glazing on the surface. At this time, reverse glazing with UV offset printing needs to be gravure printed and die-cut first, and then reverse glazing on the offset printing machine

In this way, there are two more processes of paper cutting and offset printing and glazing, which are prone to produce a large number of waste products, reducing production efficiency and finished product qualification rate
