Features:
Expanding industrial opportunitieswith new precision fabricated silicon range.
The GH print head is a result of over 10 years of Ricoh research and manufacturing optimization and is now made available for OEMs to incorporate in their aqueous and solvent ink based printer offerings.
Supports water and solvent based inks.
In addition to water-based inks, these print heads support solvent inks as well.
Multi-drop technology enables gray scale expressions.
These print heads support multi-drop-based droplet control for instantly consolidating the ink that is discharged from the nozzle at high speeds before it reaches the surface of the medium. Droplet volume control enables full control of ink discharge from small to large droplets.
