image:Single-pass 600 dpi high-resolution printing and support for multiple ink colors

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.

Support for gray-scale

Achieves excellent gray-scale rendering at up to 4 levels.

Excellent durability and extended service life

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.

Support for aqueous ink

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.

Variable drop volume capability

The multi-drop capability allows the creation of a range of drop sizes enabling gray-scale printing.
