Electronic Ink-O Meter

This machine is used for measuring viscosity and misting of ink on the printing press. It measures the torque required for shearing the ink between metal roller and rubber roller. This Inkometer is composed of metal roller rotating at a circumferential speed, top roller driven on it, and swing frame supporting the top roller shaft. At first, the metal roller is rotated without ink on it, which makes the top roller in contact with the metal roller, rotate by frictional force acting on the contact surface, producing initial torque on the swing frame. It is the torque in idle operation without ink. Then, the roll is rotated with ink on it. The frame receives additional force due to ink tacking. Torque in this Slate expresses the ink tack.
