Abstract
A print head for a pagewidth printer includes a substrate that defines a plurality of ink inlet channels. A plurality of nozzle arrangements is positioned on the substrate. The nozzle arrangements are in fluid communication with the ink inlet channels and are the product of an integrated circuit fabrication process. The nozzle arrangements define a pattern which is the result of carrying out successive replications of one nozzle arrangement with predetermined rotations and multipliers on a reference grid.

A print head for a pagewidth printer, the print head comprising
- a substrate that defines a plurality of ink inlet channels;
- and
- a plurality of nozzle arrangements that is positioned on the substrate, the nozzle arrangements being the product of an integrated circuit fabrication process and being in fluid communication with the ink inlet channels, and defining a pattern which is the result of carrying out successive replications of one nozzle arrangement with predetermined rotations and multipliers on a reference grid.
A method of fabricating print head, the method comprising the steps of:
- forming a unit cell on a reference grid, the unit cell representing a nozzle arrangement to be fabricated on a substrate;
- carrying out successive replications on the unit cell with predetermined rotations and multipliers to form a plurality of unit cells on the reference grid;
- and
- fabricating a plurality of nozzle arrangements on the substrate using the plurality of unit cells.
