Abstract

PURPOSE:To keep the viscosity of ink liquid at a constant value in a good accuracy without detecting the viscosity of ink directly by a method wherein the amount of ink consumed for printing and the standard level of the ink upon circulating (upon printing) are monitored. CONSTITUTION:New ink is poured into a measuring chamber 23 from an ink cartridge by opening a valve V1 and when a level sensor S1 has become ON the valve V1 is closed and a valve V2 is opened to pour the new ink into an ink tank 25. When a specified amount of the ink is poured and a sensor S2 has become OFF, the valve V2 is closed and a valve V3 is opened to pour a solvent medium. Next, sensors S4, S3 determine whether a solvent medium tank 24 is empty or not and whether the ink in the ink tank 25 has arrived at the standard level or not, and a viscosity control operation is finished if the tank 24 is not empty and the ink in the ink tank 25 has arrived at the standard level. Thus, the viscosity of the ink liquid may be kept at a constant value.
