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