The development and composition of uv ink.

Uv ink is a rapidly developing green and environmentally friendly ink. Compared with
heat-setting and volatile drying inks, it has low-temperature rapid curing, does not
contain volatile organic solvents, has less pollution, occupies a small area, has high
efficiency and low energy consumption. Features. With the increase in the variety of
uv curing raw materials and the sharp drop in price, the growth rate of the amount
and variety of uv inks is surprising, and the application field is also expanding,
and there are various uv special inks with different functions and varieties. For example,
using the characteristics of uv materials that do not contain volatile solvents,
uv embossed inks, Braille inks, crystal inks, and marble inks have been developed;
using the characteristics of high crosslinking density, good heat resistance and wear
resistance of cured films, developed uv solder mask, uv character ink, etc.
The application of uv curing system in printing began in the United States. The main
products are uv ink and uv varnish for lithographic printing, which are applied to
multi-color offset printing machines. The resin used is acrylic oligomer. A drying system
containing 6 high-power ultraviolet mercury lamps of 80W/cm is used for printing,
and the curing time is a few seconds. Since then, uv curing systems have been widely
used in offset printing, letterpress printing, and screen printing.

The composition of uv ink, the main components of uv ink are polymerizable prepolymers,
photosensitive monomers, photoinitiators, and the auxiliary components are coloring
pigments, fillers, additives, etc.
