Abstract
A liquid ink delivery system for use in an inkjet printer includes a plurality of conduits. Each conduit is configured to deliver liquid ink from reservoirs to printheads. The conduits are essentially comprised of a first material which is non-reactive with the liquid ink and which does not facilitate cooling or congealing of the liquid ink as the ink passes through the conduits. The conduits also include coatings applied to the first material that have further properties suited to delivery of ink and additives within the liquid ink. In one embodiment, an oxygen impermeable coating is applied to the conduit to reduce the risk of the ink or an additive within the ink oxidizes during transport through the conduit.
