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.
