UV Printing

U V printing is a digital method of printing using ultra-violet lights to dry the printed ink as it is distributed. Immediate drying of coatings means a smoother look, resulting in a finer, detailed finish. This type of printing can be applied to almost any surface.

The idea of UV printing was first proposed in 1990, but was in fact introduced as a means of quickly drying gel nail polishes used in manicures. Only then did the printing industry cotton onto this method of printing. Much the same as other printing methods, the variance is in the inks and drying process used. While traditional printing methods require additional powders during the ink offsetting process and ultimate drying, this does not.

In traditional printing, solvent inks are used; these can evaporate and release (VOC’s) volatile organic compounds which damage the environment. UV printing is environmentally friendly with about a zero carbon footprint.

The science behind the drying or curing procedure is fascinating to say the least. High intensity light is absorbed, undergoing a chemical process known as chemical cross linking. This causes the ink or coating to harden in milliseconds, resulting in a fabulous gloss finish. This method is durable and weather resistant, making it the perfect print solution for outdoor signs.

While UV printing can be done on any acrylic material, you cannot print on fabrics and clothing Why? Things like t-shirts are so absorbent that the ink will penetrate into the fibres, where the UV light cannot go. The ink has to be cured, and if the UV light cannot go there, resultantly, no to printing. Leather or winter style clothing with plastic type materials, eg, hoodies and windbreakers, can be printed on. Phone cases and glass are also great surfaces for this type of printing. Why? Simply because the ink will not be absorbed.
