Abstract
Disclosed is a pigmented fluid delivery system for an inkjet printing system. The pigmented fluid delivery system comprises a first printer component and at least a second printer component. The first printer component has a fluid outlet in fluid communication with a supply of pigmented fluid defined by particles suspended in a carrier fluid. The second printer component has a fluid inlet releasably connectable to the fluid outlet of the first printer component. The fluid inlet includes a filter compatible with the supply of pigmented fluid. The filter is an open weave screen defining a plurality of pores. The pores are sized to allow passage of the pigmented fluid while preventing clogging from flocculation of the particles and evaporation of the carrier fluid.
