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 specified 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 state expresses the ink tack.

This instrument is used for measuring viscosity of gravure printing ink, etc. The cup is immersed in the subject liquid. On pulling up the cup from the liquid, start the stopwatch to measure the time till the liquid is completely discharged from the cup.
Select a suitable cup so that the time length may be within 20 to 40 seconds.

The spread meter is one of methods for measuring fluidity of lithography and letterpress printing inks. This instrument is used to determine “spread” of ink. Test principle: a certain amount of ink is placed between two parallel plates, to deform the ink by dead weight of the plates. Along with time elapsed, the ink spreads in circular shape. With increase of the circular area, pressure applied on the ink decreases. After a certain length of time, the diameter of the spread ink is measured. Yield value is determined from the ink spreading speed.
