Abstract

This invention generally relates to the deposition of material for electronic devices, particularly molecular electronic devices such as organic light emitting diodes, by an ink jet-type process. The invention is particularly concerned with droplet, volume measurement and calibration techniques and deposition methods.A method of determining the volume of a droplet of fluid ejected from an orifice of a print head of an ink jet-type printing apparatus is described. The method comprises controlling the print head to eject a plurality of droplets from said orifice such that said droplets combine in flight to form a single, larger droplet; determining the volume of said larger droplet by measuring said larger droplet; and determining the volume of one of said plurality of ejected droplets using said determined volume of said larger droplet.
