Abstract
The printhead can include a nonwebbed diaphragm layer, an aperture plate layer, and a first webbed layer and a second webbed layer interposed between the diaphragm layer and the aperture plate layer. The nonwebbed diaphragm layer can be configured to deflect and eject ink from the print head during printing. The aperture plate layer can include a plurality of nozzles from which ink is ejected during printing. Each of the first and second webbed layers can include a first surface having a first surface area and comprising a plurality of first openings, a second surface opposing the first surface and comprising a plurality of second openings, and a web comprising a portion of the first surface, a portion of the second surface and a plurality of holes extending between the plurality of first and second openings. The printhead can be formed, in part, of alternating webbed and adjacent nonwebbed layers.
