Test inks offer a quick and easy way to assess the surface energy of solids and are particularly suitable for quality assurance in industrial practice.

Principle of the method


The test ink is applied to the surface to be tested using an applicator, such as a cotton swab or brush. Depending on whether the ink spreads into a uniform film or contracts into drops within approximately 2 seconds, it can be determined whether the surface energy of the substrate is greater or less than the surface tension of the ink.


By successively testing with inks of different settings, the threshold value at which wetting still occurs can be determined.

The prerequisite for this is that the surface is clean, dry and free of grease.
