Abstract: A packaged, degassed printer ink supply is provided, the ink supply including ink-containment vessel, a substantially degassed volume of ink contained within the ink-containment vessel, and a removable, sealable outer protective container having a low permeability to air and surrounding at least part of the ink-containment vessel to define an atmosphere between the ink-containment vessel and the outer protective container. The atmosphere between the ink-containment vessel and outer protective container is modified relative to ambient atmosphere outside of the outer protective container to decrease a diffusion rate of at least one component gas of air into the ink-containment vessel.

Abstract: Techniques for air management in an inkjet printing systems. A method includes providing an ink supply for holding a supply of liquid ink, the ink supply including high barriers to air diffusion, filling the ink supply with a quantity of liquid unsaturated ink, storing the filled ink supply for a storage time interval or until needed, installing the ink supply in an inkjet printing system including an inkjet printhead, supplying unsaturated ink from the ink supply to the inkjet printhead for printing, and allowing the unsaturated ink to absorb air introduced into the printing system, and ejecting droplets of the liquid ink from the printing system during the printing.
