Printing Ink Scraper Bar

The printing water-oil coating rod is a coating tool that evenly spreads a mixture of water and oil on the substrate surface using a metal rod to form a thin layer. It is used in pre-press treatment to enhance ink adhesion or adjust surface properties, commonly found in packaging printing and label production.
Selection
When selecting, consider the substrate type and printing requirements. Metal materials require corrosion resistance, and the rod diameter affects the coating thickness. The surface finish determines the uniformity of coating application, and the length should match the printing width. Choose the appropriate hardness based on the characteristics of the water-based or oil-based formulations.
