With 1,280 nozzles configured in 4 x 150dpi rows, this head achieves high-resolution 600dpi printing. Isolated ink paths enable a single printhead to jet up to two ink colors.
Achieves excellent gray-scale rendering at up to 4 levels.
Ricoh inkjet print heads are made of stainless steel. These heads are highly robust and offer excellent anti-corrosion properties for multiple inks, resulting in excellent durability and extended service life.
These printheads are dedicated to aqueous ink and suitable for applications such as textiles and labels. Additionally, the ink path is isolated from the actuator (piezo elements) , i.e. no ink contact.
The multi-drop capability allows the creation of a range of drop sizes enabling gray-scale printing.
Inkjet head with support for multiple nozzles and colors (Enhanced aqueous Ink compatibility)
Choose from two-color or four-color models to suit your application.
