Abstract: Islands of barrier layer material of an inkjet printhead are disposed between an ink source and the ink feed channels leading to the ink firing chambers to filter particles in the ink. Dimensions of the ink feed channels and ink ejecting orifices have been reduced in size and the thickness of the barrier layer has been made thinner. The nominal size of the filter pores is less than the barrier layer thickness while the width of the ink feed channels and the bore diameter of the orifices is larger than the barrier layer thickness.
