The Emerald QE-256/80 AAA printhead features 256 independent channels, arranged in a single row of nozzles at 100 dots-per-inch spacing.

It is designed to eject adjustable 80 to 200 picoliter drops in binary jetting mode or a 80-picoliter fundamental drop in grayscale mode. This is done at a nominal 8-meter per second drop velocity when jetting fluids in the 10 to 14 centipoise range. Unparalleled flexible modes of operation include adjustable binary drop size and grayscale capability. Robust field proven metal nozzle plate technology provides precise drop placement accuracy of a wide variety of ink types, including UV-curable, solvent and aqueous.
