Abstract
An ink containment vessel characterized by improved resistance to the corrosive effects of ink, the ability to prevent air entry into the ink, and enhanced dimensional stability. The system also avoids the evaporative loss of volatile components from the ink supply. The ink containment vessel is produced from polyethylene naphthalate, at least one liquid crystal polymer, or polyethylene naphthalate combined with at least one liquid crystal polymer. The storage of ink within vessels made from the specialized materials listed above offers multiple benefits as previously noted and substantially improves the operational efficiency of the entire ink delivery system.
