Abstract
A nozzle plate (201) for use in a liquid droplet production apparatus and such apparatus, the nozzle plate comprising a flexible substrate having a linear array of nozzles that extend through said plate, said nozzles being arranged in at least one line, forming thereby a nozzle-bearing region, wherein the substrate is curved so as to impart an increased longitudinal stiffness to it. The apparatus comprises a piezo actuator (202, 203), which may have slots (211) separating fingers acting on the nozzle plate (201). The nozzle plate may be separable form the actuator.
