Abstract
A UV/LED printing and finishing process is disclosed. The printing and finishing process improves the manner in which printing, permanent bonding, and finishing is performed on products containing low surface energy plastics, such as high-density polyethylene furniture. The process includes abrading a surface of the low surface energy plastic and then applying a corona or plasma treatment to the surface of the low surface energy plastic to increase the adhesion capabilities of the surface. Once the surface has been treater, the process may include printing a polymer ink onto the surface of the low surface energy plastic, such as by utilizing a UV/LED flatbed or hybrid printer. The process may also include curing the printed surface of the low surface energy plastic, and then finally applying a clear inorganic top coating onto the printed surface to protect the UV/LED cured polymer ink.
