ABSTRACT:
A system for controlling the viscosity of flexographic and gravure printing ink. The system includes a variable weight hydrometer which monitors the density of circulating printing ink. The hydrometer is in cooperative relationship with a supply of solvent. When the density goes above a predetermined level solvent is fed to the ink until the predetermined level is reached.
