Zusammenfassung:	A thermal ink jet print head with an orifice plate for defining numerous of orifice apertures and numerous strain relief elements. 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, or cause the edges to move in a direction perpendicular to the plane of the plate, or otherwise provide a thin cross section that deforms more easily, thereby limiting strain in other portions of the plate.
