Abstract
A nozzle plate for an ink jet print head and method therefor is provided. The nozzle plate has a polymeric layer, an adhesive layer attached to the polymeric layer defining a nozzle plate thickness and ablated portions of the polymeric layer and adhesive layer defining flow feature of the nozzle plate which contain ink flow channels, firing chambers, nozzle holes, an ink supply region and one or more projections of polymeric material in the ink supply region of the nozzle plate. The one or more projections are selected from the group consisting of an elongate portion of polymeric material having an ablated portion surrounding the elongate portion, partially ablated spaced elongate fingers having a height which is less than the thickness of the nozzle plate which are parallel to and offset from the ink flow channels, and a plurality of spaced projections having a height which is less than the thickness of the nozzle plate extending from the flow feature surface adjacent the ink flow channels having a spacing between adjacent projections which is sufficient to trap debris before the debris enters the ink flow channels to the firing chambers.
