摘要

For an inkjet printhead (10) having at least one nozzle (24) with heater elements (28a, 28b) predisposed to direct the flow of ink drops (37) through the nozzle (24), a system and method of compensating for the effects of defects in the inkjet printhead (10) to permit compensation in the direction of ink drops (37) ejected from the nozzle (24). A thickness is then added to one or more heating elements (28a, 28b) of the inkjet printhead (10), such thickness calculated to compensate for the misdirection. The heater elements (28a, 28b) are immersed in a electroplating solution (42) and a voltage differential (40) applied to cause the electroplating solution (42) to form a electroplated coating (44) which acts to compensate for a misdirection of ink stream flow (36) out through at least one of the nozzles (24).
