A thermal ink jet print head (10) with an orifice plate (14) for defining numerous of orifice apertures (26) and numerous strain relief elements (32). Each strain relief element is a closed slit between abutting and separable portions of the plate, such that a stress applied to the plate across the strain relief element will tend to open the slot to limit strain in other portions of the plate.
