INKJET PRINTING APPARATUS AND INKJET PRINTING MATHOD USING THE SAME

摘要

PURPOSE: An inkjet printing device and a inkjet printing method using the same are provided to generates the magnetic field in a plate and mounts a hole sensor sensing the magnetic field to the inkjet head part, thereby preventing the collision of an inject head and plate or a printing object without additional sensor. CONSTITUTION: A plate(30) generates the magnetic field and locates a printing object. An inkjet head(10) comprises a nozzle and a hall sensor(20) sensing the intensity of the magnetic field. A controller(60) controls the distance between the upper surface of the printing object and the nozzle according to the strength of the magnetic field sensed by the hall sensor. The hall sensor installs to the lower part of the ink-jet head. A first driving unit is combined in the ink-jet head and moves the ink-jet head perpendicularly.
