ABSTRACT:
A method and apparatus for depositing a soluble material, such as an organic polymer, onto a substrate uses an inkjet print head. The substrate is viewed from the underside by a CCD microscope during the deposition of an organic polymer droplet onto a well provided in a bank structure. As the organic polymer droplets are viewed when in wet condition they are more clearly visible and any offset or deviation detected between the deposited droplet and the well can be used to reposition a platen supporting the substrate. The substrate is viewed with light having a wavelength to which the substrate is transparent and, preferably, which does not include a wavelength component within the absorption region of the polymer.
