UV Curing Inks and its advantages

A variety of inks are used in the label printing industry today. Few examples are ink/water balance, fountain solutions, heat-set, cold-set and energy curable inks. UV cured ink is a completely solid system that is dried using photochemical processes.  Inks that are made from fluid polymers and monomers are exposed to high intensity ultraviolet light in a reactor. The exposure to UV light releases the free radicals and causes polymerization of the substance and a dry ink film containing the pigment is left behind. The applications of UV cured inks go beyond printed labels. These inks are used in electronics, automobile glass and plastic decorations and many more areas. Labels Manufacturers in India have been using UV cured inks in speciality printing like liquid cartons, flexographic printing and cosmetic packaging.

The advantages of UV cured inks

The first advantage of these inks is that they are very easy to handle, for the simple reason that the ink is completely dry. The dry ink has many advantages like trouble free operation in the printing machine and there is no threat of ink clogging. The UV ink also does not dry on screen and this makes it possible for printers to run for extended periods of time and achieve very high production throughput.

Absence of any volatile organic compounds (VOCs) makes the ink more environmentally friendly as well. When compared to heat-set inks, the UV cured inks have no toxic solvents and thus no gaseous emissions.

The colour value of the UV inks is also excellent. Most UV inks range from being transparent to translucent. This higher degree of transparency in inks translates to a very clean colour gamut. This makes such inks perfect for processes requiring four or more colour processes graphic printing.

These advantages of UV inks especially enable printing of sophisticated and highly detailed bottle labels and self adhesive labels. UV inks are a blessing to Label Manufacturers allowing them to print high quality tags in larger numbers within shorter periods of time.
