a method for bonding a polymer layer to an outlet plate for an inkjet print head has been developed that enables the polymer layer to be attached to the outlet plate with little or no bowing of the polymer layer . the method includes aligning recesses in a bonding plate with channels in an outlet plate , interposing a polymer layer between the bonding plate and the outlet plate , and pressing the bonding plate against the polymer layer to bond the polymer layer to the outlet plate .
