Support for different inks

With its built-in heater, these heads are capable of jetting high-viscosity inks. 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 grey-scale printing.
