Dynamics of entrained air bubbles inside a piezodriven inkjet printhead
- Entrapped air bubbles in piezo-driven inkjet printing: Their effect on the droplet velocity. de Jong, Jos; Jeurissen, Roger; Borel, Huub; van den Berg, Marc; Wijshoff, Herman; Reinten, Hans; Versluis, Michel; Prosperetti, Andrea; Lohse, Detlef // Physics of Fluids;Dec2006, Vol. 18 Issue 12, p121511
Air bubbles entrapped in the ink channel are a major problem in piezo-driven inkjet printing. They grow by rectified diffusion and eventually counteract the pressure buildup at the nozzle, leading to a breakdown of the jetting process. Experimental results on the droplet velocity udrop as a...

- Wide format beyond offset. Robertson, Mike // American Printer;Feb2009, Vol. 126 Issue 2, p15
The article discusses the popularity of wide-format inkjet equipment among printing businesses. As noted in the January 2008 issue of "Grand Times" periodical, these machines initially faced a hostile reception. Wide format imaging is now high on the list of valued imaging solutions, according...
- Ink-jet delivery of particle suspensions by piezoelectric droplet ejectors. Reis, Nuno; Ainsley, Chris; Derby, Brian // Journal of Applied Physics;
The volume and velocity of droplets ejected from a piezoelectric droplet generator, as used in ink-jet printing, have been studied for a range of concentrated suspensions of submicron alumina particles as a function of driving signal voltage, frequency, and peak shape. Drop velocity and volume...
