Abstract
The invention relates to a droplet break up device comprising: a chamber for containing a printing liquid comprising a bottom plate; a pump for pressurizing the printing liquid; an outlet channel having a central axis, provided in said chamber for ejecting the printing liquid; and an actuator for breaking up a fluid jetted out of the outlet channel. The actuator is provided around the outlet channel, arranged to symmetrically impart a pressure pulse central to the outlet channel axis. Accordingly, smaller droplets can be delivered at higher frequencies.
