摘要：
Inkjet cartridge assemblies are provided for shipping with the internal pressure of their ink containers set during assembly at a reduced level at least 2 inches Hg gage below atmospheric pressure at sea level to avoid leaking during shipping. Preferably, the ink containers have an internal pressure set at least 9 inches Hg gage below atmospheric pressure at sea level.
