A method of forming a nozzle element for an ink jet print head, wherein material is removed from the nozzle element by means of a laser to form the nozzle. A mask is irradiated with a laser beam in such manner that at least one sub-beam is passed through the mask, whereafter the material is removed by means of the sub-beam. Inhomogeneity of the laser beam is compensated for by using, for each nozzle laser, radiation originating from different parts of the laser beam, whereby the nozzle is formed with an "average" laser beam.
