Determines the tack of offset litho ink

Determines the tack of an offset litho ink. Available with measuring and distribution roller suitable for either conventional dried offset ink or UV cured ink. Complete with cooling unit. Complies with ASTM D4361. Manufactured by Thwing Albert.

By simulating the dynamic conditions that occur in the printing process, the Electronic Inkometer provides rapid and reliable data on the tack and length of ink. It measures the integrated forces involved in ink film splitting and the effects of speed, film thickness, temperature and solvent evaporation.

Advanced microprocessor control ensures the highest accuracy and efficiency for the confident comparison of new and different inks in research and development, quality control and process evaluation.

The test results are numerical values, in gram metres, for the torque required to “work” the ink film at known rates with predetermined film thickness and temperature. These torque readings are actual measurements of the tack of the ink. The length of the ink is calculated by analysing the difference between readings at different roller speeds.

Operation
Consists of three rollers: upper composition covered roller; vibrator composition covered roller; temperature-controlled roller.

The pressure between the two composition covered rollers, their speed of rotation and the temperature of the ink film reproduce on-press conditions. These rollers are suitable for testing all types of printing inks, having definite plastic properties and containing no volatile thinners.

Temperature is controlled by circulating water from a control unit, composed of a refrigerated bath circulator with a stainless steel reservoir that is separate from the tester and may be placed wherever convenient.

Water temperature settings are 32 °C or variable. Heat adjust control 100 – 1000 W. Reservoir capacity 9.5 litres. Power consumption 5.5 A at steady rate.
