Han's Laser Plasma Cleaning Equipment - Demonstration of Surface Treatment Before Screen Printing Plasma surface treatment is a technology that uses plasma to treat the surface of a substrate, which can improve the adhesion, wettability, and chemical activity of the surface, thereby enhancing the adhesion and uniformity of printing ink or transfer ink on the surface. At the same time, plasma treatment can also form a layer of oxide film or functional base film on the surface, improve the activit
