Abstract

Apparatus and method for projecting liquid in the form of a sheet for deposition on a target comprises a nozzle having a slot 10 of width not less than 250 microns to which the liquid is supplied. High voltage is applied to the liquid and the liquid is supplied to the slot at a flow rate such that the liquid is formed as, and is maintained in the form of, a sheet by preponderantly electrostatic forces thereby effecting deposition of the sheet on to the target.
