Product Advantages
1.Ricoh GH2220 head printing speed 5 times faster than EPSON head ( Epson 2-4 m² /h; Ricoh GH2220 8-15 m² /h)
2.Ricoh GH2220 printhead is the only one industrial nozzle ink droplets can reach the accuracy of 3PL, but also the gray head.
3.Gh2220 printhead is the highest accuracy one among industrial printhead,the smallest ink drop size is 3pl.
4.Suitable for these ink: uv ink, eco solvent ink,sublimation ink ,water based ink.
5.Suitable for: eco solvent printer,uv flated printer,large format printer
6.Cost is much more economic than Gen4/5,DX5/7 printhead etc.
Features:
Expanding industrial opportunities with 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, solvent based inks and UV curable inks.In addition to water-based inks, these print heads support UV inks & 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.
