Ink Four-Sided Drawdown Bar

The four-sided ink applicator forms four different thicknesses of ink coatings on the test surface by adjusting the angle between the blade and the substrate. It is used to simulate printing conditions and evaluate ink properties such as hiding power and leveling. It is suitable for quality control of printed materials and ink formulation development.
Selection
Consider substrate compatibility when selecting to ensure the Coater matches commonly used substrates. The coating thickness range must meet industry standard requirements. The blade material should be wear-resistant, with a structural design that ensures uniform coating. Ease of operation affects testing efficiency, and maintenance costs should be taken into account.
