Instrumentation Test: Inkometer Tack Test

Register to read the introduction… However, when the results were compared, tack values were affected more by the temperature than by speed (friction) itself. In the results portrayed above, when the Inkometer was set at 90 degrees Fahrenheit, 800 RPM, the initial tack value measured at 1 minute was 8.2, as opposed to 10.4 when the speed increased to 1200 RPM. Furthermore, when the same results were compared to that of 100 degrees Fahrenheit, both 800 RPM and 1200 RPM, tack values taken at 1 minute had marginal differences, 7.0 and 8.2, respectively. This shows that as the temperature increases, the tack of an ink in a press decreases. The heat liquefies the ink, which makes the ink less viscous (thick), allowing it to become less tacky when placed on top of paper through the rollers.
The ending results between the similar rpm tests were similar in values. After 10 minutes the higher rpm’s tack value was closer to what research suggests should be standard. Research indicates that a tack value for web offset
