Abstract
A method of optimizing a relationship between fire energy and drop velocity associated with a printhead is provided. A test pattern is printed by selectively supplying energy distribution signals to a plurality of actuators of the printhead. The energy distribution signals have distinct energy profiles. The test pattern is scanned to obtain drop velocity information corresponding to the energy distribution signals. Based on the drop velocity information, an energy profile is determined that optimizes the relationship between fire energy and drop velocity.
