Emerald QE-256/80 AAA Printhead
The Emerald QE-256/80 AAA Printhead is a high-performance industrial inkjet printhead featuring 256 independently addressable channels arranged in a single inline nozzle row at 100 dots-per-inch (dpi) spacing. It is engineered for demanding printing applications requiring flexible drop control, consistent jetting, and precise drop placement.
This printhead supports adjustable 80 to 200 picoliter drop sizes in binary jetting mode and a fixed 80 picoliter fundamental drop in grayscale mode. Operating at a nominal 8 m/s drop velocity, it is optimized for jetting fluids with viscosities ranging from 10 to 14 centipoise.
Utilizing a robust, field-proven metal nozzle plate technology, the QE-256/80 AAA delivers exceptional accuracy and reliability across a wide range of ink chemistries, including UV-curable, solvent, and aqueous-based inks. Advanced features such as VersaDrop™ binary and grayscale jetting modes, an integral temperature sensor, and OEM-accessible non-volatile memory make this printhead ideal for industrial scanning printer architectures and OEM inkjet platforms.
