<p>An ink-package assembly (1; 28) including an ink package (2; 26) fluid-tightly containing a mass of an ink, and a sealing wrapper (4) fluid-tightly enclosing the ink package, wherein an interior space of the sealing wrapper is charged with an inert gas such as a helium gas, which has a lower degree of solubility in the ink, than the air. The interior space of the sealing wrapper is evacuated to a reduced pressure of -20kPa and -60kPa with respect to the atmospheric pressure, as needed. The ink package includes an ink bag (4) and is provided with a spout (7) having a passage (6), and a cap (8) for closing the passage. Where the sealing wrapper is evacuated, the ink package preferably further includes an ink-bag casing (12) accommodating the ink bag, and a reinforcing structure (23) interposed between the casing and the ink bag, to prevent deformation of the ink bag. Also disclosed is a method of producing the ink-package assembly. <IMAGE></p> |
