<p>This invention is concerned with a method of curing solvent-free inks by application of a powdered resin to a freshly printed surface. Powder, which does not adhere to the ink, is removed and the printed surface then is passed through a heating tunnel where the resin melts, thereby curing the ink. Optionally, the printed surface may be leveled mechanically following curing. Such leveling produces a higher gloss. Air pollution which normally is caused by solvent fumes in conventional processes is eliminated by this method. Moreover, heat energy is conserved as the need to vaporize a solvent and to carry-off the heated vapors is eliminated.</p> |
