Patent ID: 8668308

Claim:
A printing apparatus comprising: a first plurality of inkjet stack layers having a first array of inkjet ejectors, the first array of inkjet ejectors having a width in a cross-process direction and a length in a process direction; a second plurality of inkjet stack layers having a second array of inkjet ejectors, the second array of inkjet ejectors having a width in the cross-process direction and a length in the process direction, and the second array of inkjet ejectors being displaced from the first array of inkjet ejectors in the process direction; an aperture layer having a first array of apertures and a second array of apertures that are separated from one another in the process direction by a predetermined distance, the aperture layer being bonded to the first plurality of inkjet stack layers to enable the first array of inkjet ejectors to eject ink through the first array of apertures and to the second plurality of inkjet stack layers to enable the second array of inkjet ejectors to eject ink through the second array of apertures; and a joint formed between the first plurality of inkjet stack layers and the second plurality of inkjet stack layers, the joint extends in the cross-process direction to enable the first array of inkjet ejectors to move relative to the second array of inkjet ejectors in response to the aperture layer being flexed to enable the first array of inkjet ejectors and the second array of inkjet ejectors to be positioned with the predetermined alignment about a curved surface.
