In this research, quality of jetting is studied with identifying pinching behavior for droplet formation. The DOD, i.e., drop on demand method-based inkjet printer with a piezoelectric actuator and hydraulic pressure control system and jet driver is used for experimentation. Strobing technology is used with a high resolution of camera for collecting image recordings. The experiment is conducted by generating the random values table for operating conditions for each pressure set from -2.00 to pressure -6.00. The jetting behavior and quality of jetting is observed and characterized with nature and description for jetting, including satellite formation, alignment, ligament formation, stability and unstable nature for jetting. The effect of operating parameters such as pressure, voltage, excitation waveform, dwell time, echo time, fall time, rise time on jetting and droplet formation are discussed with a case study with DI water. Further experiments are conducted and image recordings are observed for expected pinching behavior. Experiment results show that classification for pinching behavior, quality of jetting and optimal operating conditions are recognized with image recordings.","**To request an accessible version of the file(s) associated with this item, contact library@buffalo.edu.
