Abstract
A method of depositing material on a surface (136) is described in which a bulk medium (for example ink 122) in the form of a composition of dispersed insoluble material (for example ink particles) and a support medium is supplied to a cell (120). A movement of the insoluble material within the bulk medium is effected towards a transfer aperture (128) within the cell, thereby concentrating the insoluble material within the bulk medium. Thereafter the insoluble material is removed from the concentration within the bulk medium through the aperture (128) and deposited onto the surface (136).
