Ink-jetting apparatus and ink-jetting method

摘要

An ink-jetting apparatus and an ink-jetting method are disclosed. An ink-jetting apparatus for jetting an ink through a nozzle which includes a chamber containing the ink, an actuator providing a pressure to the chamber, and an electrostatic part forming an electric field around the nozzle, may provide high resolution and a wide range of grey scale by using a piezoelectric method with an electrostatic method in combination.
