Abstract
Screen printing to an edge of an object without the flow of print ilk over the edge and to a supporting platen is realized by applying a flow of gas from the platen over the edge of the object and opposing the flow of print ink. The platen can have a support surface including a groove or a plurality of holes arranged to match the edge of the wafer. The wafer can include a semiconductor wafer such as a photovoltaic cell, and the gas can include air, nitrogen, or an inert gas.
