Abstract
In an ink jet printer, a method of selecting an optimized energy level associated with a target ink drop velocity including the acts of: moving a printhead across a print medium at a plurality of scan velocities including a first velocity and a second velocity, printing at least one set of patterns on the print medium by supplying at least one predetermined energy level to at least one actuator of the printhead, the at least one set of patterns including a first pattern printed at the first velocity and a second pattern printed at the second velocity, associating the first pattern with the second pattern and selecting the optimized energy level associated with the target ink drop velocity.
