Abstract
Manufacturing an inkjet printhead and orifice plate by providing upstanding spaced apart barrier walls on the orifice plate to separate adjacent firing chambers on the printhead. A plurality of orifice plates are initially created in a one-layer array on a workpiece. An abrasive member is controlled to contact and truncate end edge portions of the barrier walls on the workpiece to create mutually coplanar surfaces for engagement with a substrate in order to help prevent cross-talk between adjacent firing chambers.
