ABSTRACT:
The invention provides a method and apparatus for depositing a soluble material, such as an organic polymer, onto a substrate using an inkjet print head. The substrate is provided with an array of alignment marks and the material in solution is deposited when substantially aligned with one of the alignment marks to provide an alignment dot of the material in solution. The alignment dot is viewed before the deposited material in solution has dried. Cross-shaped alignment marks are used to facilitate viewing of the positions of the alignment dot.
