What is a Piezo Inkjets?

0

Most commercial & industrial inkjet printers us a piezoelectric material in an ink filled chamber behind each nozzle instead of a heating element. When a voltage is applied, the piezoelectric material changes shape or size, which generates a pressure pulse in the fluid forcing a droplet of ink from the nozzle. Piezoelectric (also known as Piezo) inkjet allows a wider variety of inks than thermal or continuous inkjet but the print heads are more expensive. Piezo inkjet technology uses stationary heads, robust construction and are designed for high volume production, faster print speeds and lower costs. There is a drop-on-demand process, with software that directs the heads to apply between 0 to 8 droplets of ink per dot and only where needed.
