Technology overview
Head Technology
Shear Mode Piezo Inkjet Print Head
Konica Minolta inkjet heads are able to handle a wide range of inks
to meet the requirements of various industrial applications. The
principle of shear mode piezo actuation with shared wall structure
allows lower power consumption as well as a high-density nozzle array.
On-demand dot size modulation, sometimes referred to as grey-scale
mode, enables the printing of high quality images and functions to
increase productivity. All the development work is based on advanced
computer simulation techniques that can precisely predict the droplet
formation process resulting from differential ink characteristics.
The principle of ink ejection
Micro scale channels made from piezo electric material are made to
contract by the application of an electric charge. As the channels
contract, ink contained in the channel is forced out through the nozzle
as a droplet. As the channel returns its original state, capillary
action causes ink to flow into the channel making it ready to produce
the next drop.
