High-density inkjet nozzle array for an inkjet printhead
First Claim
1. An inkjet printhead that comprisesat least one support structure;
- and a plurality of nozzle arrangements that are positioned on the, or each, support structure, each nozzle arrangement including a nozzle chamber defining structure that is positioned on the substrate and that defines a nozzle chamber, the nozzle chamber defining structure including a roof that defines an ink ejection port that is in fluid communication with the nozzle chamber, wherein all the nozzle arrangements are positioned in an aligned, side-by-side manner on the, or each, support structure so that the ink ejection ports of the nozzle arrangements are positioned substantially rectilinearly along a length of the, or each, support structure and the nozzle arrangements are each dimensioned so that a distance between consecutive ink ejection ports is less than or equal to 42 microns.

Abstract
An inkjet printhead includes at least one support structure. A plurality of nozzle arrangements are positioned on the, or each, support structure. Each nozzle arrangement includes a nozzle chamber defining structure that is positioned on the substrate and that defines a nozzle chamber. The nozzle chamber defining structure includes a roof that defines an ink ejection port that is in fluid communication with the nozzle chamber. All the nozzle arrangements are positioned in an aligned, side-by-side manner on the, or each, support structure so that the ink ejection ports of the nozzle arrangements are positioned substantially rectilinearly along a length of the, or each, support structure. The nozzle arrangements are each dimensioned so that a distance between consecutive ink ejection ports is less than, or equal to, 42 microns.
