PicoJet Demonstrates New Ink-Jet Printhead
After five months in development, PicoJet Inc., Hillsboro, Ore., successfully demonstrated its new
PJ-N256 drop-on-demand ink-jet printhead. Using patented, ultrasonic bonding technology, the
stainless steel printhead was shown to be able to simultaneously fire its 256 jets at 10,000 drops
per second, creating a high-resolution, 300 dots-per-inch image.
The PJ-N256 also features a metal ink channel that enables the printhead to jet a wide variety of aggressive ink chemistries; and the elimination of the use of epoxy and piezo ceramic in the ink channel, allowing the printhead to jet fluids reliably without nozzle clogging.
