INK AND SOLVENT CONTAINER FOR INK JET PRINTERS

摘要

An ink and solvent supply consists of a dual-chambered container (22). The lower chamber (24) is provided with make-up solvent, while the upper chamber (26) is provided with ink concentrate. When solvent is required, it is removed directly from the lower chamber (24). When fresh ink is required, vacuum is applied to the upper chamber (26) causing solvent to pass from the lower chamber (24) to the upper chamber (26) via a conduit (40), to dilute the ink conentrate to form fresh ink which is then provided to the printing system.
