Cold-Set Ink

A type of printing ink comprising a resin-wax vehicle that is a solid at room temperature, and must be melted in order to be printed. Heated ink rollers, form rollers, and plates keep the ink melted long enough to print, where the ink hardens upon contact with the cool paper. Cold-set inks are not used very often, save for novelty applications. (See Vehicle.) Cold-Set inks are occasionally used in screen printing by means of an electrically-heated screen, and are known as hot melt inks.
