Abstract:
A hardwearing inkjet printhead comprises a substrate 10 having an ink ejection circuit 12 and a patterned glass frit planarization layer 22 on its surface. A ceramic body 28 has a substantially flat surface 28B intimately bonded to the planarization layer. The ceramic body and planarization layer together define at least one ink ejection chamber 18 and associated ink ejection nozzle 38 with the nozzle and at least the major part of the height of the chamber formed in the ceramic body.
