Ink Film Coating Rod

The ink coating rod uses a metal rod with fixed-depth grooves on its surface. During the scraping process, excess ink is removed, forming a uniform wet film of consistent thickness on the substrate. It is used in laboratories to simulate the printing process and test ink properties such as hiding power and leveling ability.
Selection
When selecting, consider the substrate roughness to match the groove depth, with common specifications ranging from 10–200 μm; choose round or square coating rods based on ink viscosity; stainless steel material resists solvent corrosion; verify the straightness of the rod body and the accuracy of the scale markings.
