Method of manufacturing nozzle plate for ink jet printer

A method of manufacturing a printer head for an ink jet printer by applying to a plate a plurality of secondary beams from a flyeye lens including an array of lens elements and affixing the plate to a printer head body, the method comprising the steps of:

• dividing a laser beam to provide a plurality of linear beams, each said beam having a width smaller than a corresponding lens element;
• applying the plurality of linear beams to corresponding lens elements to generate the plurality of linear secondary beams;
• superposing the plurality of secondary beams on a diaphragm member so they substantially coincide to form a linear beam pattern on the diaphragm member, the lengthwise direction of the beam pattern being disposed in a direction in which openings are arranged in the diaphragm member;
• and
• projecting the image of the openings illuminated by the beam pattern onto the surface of the plate, whereby holes are formed therein to provide nozzles for ink jet printing.

A method of manufacturing a nozzle plate for an ink jet printer head by using a member having a row of openings in a predetermined direction, the method comprising the steps of:

• generating a plurality of linear beams, each said beam having a lengthwise direction;
• superposing the plurality of beams so that their lengthwise directions substantially coincide with said predetermined direction;
• and
• exposing a plate with the beams through the row of openings in the member to form a plurality of holes in the plate, thus forming the nozzle plate of the ink jet printer head.

A method of manufacturing an ink jet printer head by using a member having a row of openings oriented in a predetermined direction, the method comprising the steps of:

• generating a plurality of linear beams, each having a lengthwise direction;
• superposing the plurality of beams so that their lengthwise directions substantially coincide with said predetermined direction;
• and
• exposing a plate with the beams through the row of openings in the member to form a plurality of holes in the plate, thus forming a portion of the ink jet printer head.
