ABSTRACT:
A method is provided for maintaining the viscosity of a consumable water-containing ink supply at a constant value by measuring water vapor content of the vapor in equilibrium with the ink supply and adding a sufficient amount of water to restore the water vapor content to a predetermined value. The method has particular application for controlling the viscosity of ink used in jet ink printers.
