Abstract
A method for prevention of nozzle plate peel for inkjet printheads. The nozzle plate is bonded to the nozzle, with a layer of adhesive, and to a support, with a thicker layer of adhesive. This extra support prevents the peeling of the nozzle plate under the forces generated by, for example, a wiper blade passing over it. Spacers between the nozzle plate and support ensure the correct uniformity and constant thickness of the adhesive layer.
