ABSTRACT:
Apparatus and method for determining the viscosity of printer ink is disclosed. The apparatus includes a vertically mounted rod supported by a base. A strain gauge or load cell measures strain or pulling force existing between the base and the rod. A collar having a diameter slightly greater than the diameter of the rod and suitable for receiving a sample of ink at the gap between the rod and the collar is moved at a precise velocity. The viscosity of the ink sample is then calculated from the known physical parameters of the apparatus, the rate of shear, temperature, and the shear stress or pulling load exerted on the rod by the movement of the collar and ink sample as they travel along the length of the rod.
