An inkjet printhead including a plurality of nozzles mounted to a rigid substrate (26), each of the nozzles being adapted to eject drops of ink toward a surface to be printed; each of the nozzles also having a bend actuator (10) and an apertured roof portion (6), the actuator adapted for anchorage to the rigid substrate (26) and connection to the roof portion (6) such that in use the actuator (10) moves the roof portion (6) away from the surface to be printed, in order to eject the ink; wherein, the displacement of all points along the operative section of the actuator (10) during its movement from a de-activated to an activated state, constantly increases from zero displacement at the point of anchorage (11) to the rigid substrate (12, 26), to maximum displacement at the point of connection (13) to the roof portion (6).
