A method of forming a nozzle in an element for an inkjet printhead, a nozzle element, an inkjet printhead provided with the said nozzle element, and an inkjet printer provided with such a printhead

摘要

The invention relates to a method of forming a nozzle (7) in an element (17) for an inkjet printhead, wherein material is removed from the element by means of a laser, the nozzle being formed during this. In this method, a mask (22) is irradiated with a laser beam (21) in such manner that at least one sub-beam (24) is passed through the mask, whereafter the material is removed by means of the sub-beam. Inhomogeneity of the laser beam is compensated for in the method according to the invention by moving the laser beam with respect to the mask in a direction substantially parallel to the mask so that the sub-beam during the removal of the material originates from different parts of the laser beam. In this way the nozzle is formed with an "average" laser beam.
