Printheads provide precise, fast jetting

The Emerald QE-256/30 and QE-256/80 30-picoliter and 80-picoliter printheads combine precise, high-speed multipulse binary jetting, and versatile gray-scale operation with a durable, field-proven metal nozzle plate that supports aqueous, UV-curable, and solvent ink formulations. The models feature 256 individually addressable channels arranged in a single row at 100-dpi spacing.

The units’ design lets every jet operate concurrently with low crosstalk and excellent channel-to-channel uniformity. The Emerald QE-256/30 ejects adjustable 30 to 80-picoliter drops in binary mode or a 30-picoliter fundamental drop in gray-scale mode. The Emerald QE-256/80 is designed to eject adjustable 80 to 200-picoliter drops in binary mode or an 80-picoliter fundamental drop in gray-scale mode. Operating at a nominal 8-m/s drop velocity when jetting fluids in the 10 to 14-centipoise range, the Emerald QE-256/30 operates at firing frequencies to 33 kHz.
