title: Small fast inkdrop emission from a nozzle
ispublished: pub
subjects: other
studygroups: esgi43
companyname: Xaar plc
full_text_status: public
problem_statement: In the normal operation of ink jet printheads, ink drops are extruded through a nozzle, producing plugs with the same diameter as the nozzle. However, Xaar has observed that under certain circumstances a smaller, faster drop is emitted from the centre of the nozzle, having about one quarter the diameter of the nozzle and about twice the velocity of normal operation. The Study Group was asked to consider possible mechanisms that could lead to this unusual behaviour. If the production of such microdrops can be understood, a practical design might be viable, so allowing printing with much higher resolution and with reduced ink usage.
