Piezo inkjet technology has been used for a couple of decades. Piezo technology is activated by using an electrical charge which has been named piezoelectric technology. This print head technology is used in printers from small photo printers to large industrial systems.

Piezo technology forces the ink out of the print nozzles by using an electrical charge. Once an electrical charge is received from the devices behind the print head, the device bends backwards drawing the exact amount of ink from the cartridge into the firing chamber. The electrical process is then reversed and the small devices will bend quickly to release ink at high speeds.

The amount of ink pulled into and released from the nozzle is accurately controlled by the electrical impulse recieved by the piezoelectric devices changing how they bend. The print head ejects ink drops in a precisely controlled amount.

Piezo inkjet technology is often used in a manufacturing setting on production lines to mark products. This is used because of fast drying technology without using heat. The requirements of this technology are high speed application, long life span, large span between the print head and material and low operating cost. Because this technology enables non-contact printing, it is applied to all kinds of media applications from personal to industrial. Since inkjet printing does not require a plate, there are major cost savings. This also includes the ability for screen printing.

Piezoelectric print heads use electromechanical means rather than heat which gives the print head a longer life expectancy. Piezo printers are also capable of producing smaller droplets resulting in better photographic prints. These printers also have a larger range of ink compatibility. Ink replacement is less expensive and more readily available. Piezo heads can use solvent systems, oil-based as well as aqueous systems for ink. For more information please see the video on ehow.com.
