Fluid interconnect in a replaceable ink reservoir for pigmented ink

An ink supply system for an inkjet printing system with an inkjet print cartridge, comprising:

• a replaceable ink container for holding a supply of pigmented liquid ink, the ink container comprising a containment vessel, the containment vessel having an interconnect opening;
• an outlet screen disposed in the containment vessel and across the interconnect opening, the outlet screen having a pore size small enough to prevent air passage at operational pressures and large enough to allow said dispersed colorant particles to pass therethrough;
• a body of reservoir material disposed in the containment vessel, the body of reservoir material having a region adjacent to and in contact with the outlet screen;
• a receiving station for mounting the ink container;
• a fluid interconnect structure for establishing a fluid path from the ink container to the ink jet cartridge when the ink container is installed in the receiving station, the fluid interconnect structure including an interconnect tower having a distal end with a fluid interconnect inlet port and an inlet screen across the fluid interconnect inlet port, the inlet screen having a pore size larger than the pore size of the outlet screen and large enough to avoid clogging from dried ink pigments under typical use conditions.
