Drawdown Rod

The color development metering rod forms a uniform wet film on the substrate through the principle of gravure printing, used for laboratory proofing and color evaluation of coatings and inks. The precise grooves on the surface of the metal rod control the coating thickness, enabling rapid color development when used with a palette knife, making it suitable for quality control in the printing and papermaking industries.
Selection
When selecting, consider matching the substrate type with the rod material. Determine the groove depth based on the coating thickness requirements, with a common range of 1–200 micrometers. Pay attention to the straightness of the rod body and the precision of the grooves. Stainless steel material is suitable for conventional samples, while the hard chrome-plated version offers better wear resistance. Verify the consistency between the rod serial number and the calibration certificate.
