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.
L'invention concerne un récipient à double compartiment (22) pour l'alimentation en encre et en solvant. Le compartiment inférieur (24) contient un solvant d'appoint, tandis que le compartiment supérieur (26) contient de l'encre concentrée. En cas de besoin, le solvant est extrait directement du compartiment inférieur (24). Lorsque de l'encre neuve est requise, une pression négative est envoyée dans le compartiment supérieur (26) de sorte que du solvant passe du compartiment inférieur (24) au compartiment supérieur (26) par l'intermédiaire d'un conduit (40), que l'encre concentrée soit diluée et que de l'encre neuve qui est envoyée au système d'impression soit produite.
