Weba dyne level lower than the material’s surface energy, then the liquid will spread out over its entire surface in a uniform wet layer. If the ink’s dyne level is equal to or higher than a material’s dyne level, the liquid will become cohesive and tend to remain in droplets. Surface test fluids were introduced to give an accurate measurement

WebTest the surface energy (dyne level) of film and other nonabsorbent surfaces before printing, coating, or laminating. Also known as dyne pens, these work like a felt-tip marker. A continuous line will appear if the material meets the tester's surface energy level, while insufficiently treated material results in air bubbles and a disappearing mark.
