Characteristics
Expanding industrial opportunities with new precision fabricated silicon range.
Introducing the new GH PrintHead to complement Ricoh’s stainless steel MH series PrintHead family. The GH PrintHead 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 printheads support solvent inks as well.
Multi-drop technology enables grey scale expressions
These printheads 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.
