Solid ink (also known as hot melt ink^[1][2]) is a type of ink used in printing. Solid ink is a waxy, resin-based polymer that must be melted prior to usage, unlike conventional liquid inks.^[1][3] The technology is used most often in graphics and large-format printing environments where color vividness and cost efficiency are important.^[4][5]
