While contact angle goniometry has been around for many years, we have recently developed a way to account for the underlying surface’s micro-scale roughness.
Surface tension of inkjet inks and the wettability of the printing substrate are important factors influencing the final printing quality.
Surface roughness and wettability in paper and board
Wettability of a paper or board depends on the coatings and treatments done to it. By measuring the wettability, deviations in coatings and treatments can be observed
