Abstract
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.
Claims18
An ink-jetting apparatus for jetting an ink through a nozzle, the apparatus comprising:
- a chamber configured to contain the ink;
- an actuator configured to provide pressure to the chamber;
- and
- an electrostatic part configured to form an electric field around the nozzle.
An ink-jetting method for jetting an ink contained in a chamber through a nozzle, the method comprising:
- forming an electrified ink tip at the nozzle by a piezoelectric method;
- and
- separating at least a portion of the ink tip with an electrostatic force.
