摘要： An inkjet head nozzle plate having a hydrophobic coating layer and a method of forming a hydrophobic coating layer on the inkjet nozzle plate. The method including preparing a stamp and a nozzle plate having a plurality of nozzles, applying a hydrophobic material to the stamp, bonding the hydrophobic material to the nozzle plate by moving the stamp onto the nozzle plate and heating the nozzle plate to bond the hydrophobic material of the stamp to the nozzle plate, and separating the stamp from the nozzle plate. Portions of the hydrophobic material bonded to the nozzle plate remain at the nozzle plate to form the hydrophobic coating layer on the nozzle plate, and other portions of the hydrophobic material corresponding to the nozzles of the nozzle plate remain on the stamp and are separated from the nozzle plate when the stamp is separated from the nozzle plate.

摘要： An inkjet head having a hydrophobic coating layer and a method of forming the hydrophobic coating layer on a surface of a nozzle plate of the inkjet head. The method includes filling a wax into a plurality of nozzles formed in the nozzle plate while coating the surface of the nozzle plate with wax, removing the wax from the surface of the nozzle plate, forming a hydrophobic coating layer on the surface of the nozzle plate, melting the wax filled in the nozzles, and removing portions of the hydrophobic coating layer covering the nozzles by discharging the melted wax through the nozzles using heat and/or pressure. Therefore, the hydrophobic coating layer is uniformly formed only on an outer surface of the nozzle plate, without forming the hydrophobic coating layer in an inner surface of the nozzles, thereby improving an ink ejecting performance of the nozzles.
