Solid Ink-Jet
|
|
A type of drop-on-demand ink-jet printing system in which the ink begins as a solid and is heated to convert it to a liquid state. While it is in a liquid state, the ink drops are propelled onto the substrate from the impulses of a piezoelectric crystal. Once the ink droplets reach the substrate, another phase change occurs as the ink is cooled and returns to a solid form instantly. The print quality is excellent and the printers are capable of applying ink on almost any type of paper and transparency substrates. A solid ink-jet printer is often referred to as a phase change ink-jet printer.
