Why is knowledge of UV chemistry so important to a screen printer who either uses UV inks right now or is going to use them? Simply because UV inks are part of the UV technology, and use of UV inks should be viewed rather as an application of UV technology in screen printing. UV technology consists of three major elements: UV ink, UV reactor (or UV processor) and substrate. The chemistry of UV ink acts like a common solvent which mixes these elements together. It is my strong conviction, based on some experience, that an understanding of some UV chemistry will allow you to successfully implement …
