Viscosity is the measurement of an ink or coating's actual performance on the press. It is the measurement of a fluid's internal friction, or its resistance to flow, under varying degrees of stress, stress rates and temperatures. A change of viscosity indicates variations in pigment concentration or percentages of solids, and can show the degree of polymerization of UV-cured ink or coating.
Viscosity measurement is the most sensitive control method of printing variables which affect the quality of your finished product, and is a determining factor in final print consistency.
The PORTABLE AND DISPOSABLE VISCOMETER is a simple to use, highly affordable, and accurate viscosity measuring device. This instrument consists of a support stand, calibrated weight, controlled needle and guide, and a disposable sample tube. Viscosity of the sample is determined by measuring the falling time of the needle through a predetermined distance of the sample. The falling time is measured automatically (N002-017) or manually by a stopwatch (N002-016). For Newtonian fluid, a table or graph will be supplied with the instrument. For non-Newtonian fluid, data reduction computer software is available.
