Patent attributes
Systems and methods are provided for printhead waveform adjustment. One embodiment is a system that includes a controller that correlates a series of printhead waveforms input to a printhead with a series of optical density values output by the printhead. The controller determines a single target optical density for the printheads based on an average optical density of the printheads. Also, for each of the printheads, the controller determines a functional relationship between the parameter of the printhead waveforms input to the printhead and the optical density values output by the printhead, and determines a target printhead waveform parameter for the printhead based on the single target optical density input to an inverse of the functional relationship. The controller updates printhead settings to include information of the target printhead waveform parameter determined for each of the printheads for applying to the printheads to output ink at consistent optical density.
