Abstract
Described herein is a process and apparatus for driving a droplet ejection device with embedded multi-pulse waveforms. In one embodiment, the process includes generating a multi-pulse waveform that includes drive pulses in predetermined positions. Next, the process includes applying the drive pulses to the actuator and causing the droplet ejection device to eject a first droplet of a fluid. The process also includes applying a second multi-pulse waveform having at least one embedded pulse to the actuator and causing the droplet ejection device to eject a second droplet of the fluid. Each embedded pulse is embedded between predetermined positions of two drive pulses. In some embodiments, the first and second droplets have different droplet sizes and these droplets are ejected at substantially the same effective drop velocity.
