For most screen printers, liquid emulsion is the preferred tool for coating screens to make stencils. There is an alternative that’s often overlooked and undervalued: capillary film. Capillary films are sheets of hardened emulsion on a polyester backing. The emulsion side of the film is applied directly to a wetted mesh screen. The emulsion forms a firm bond with the mesh as it dries, and the backing is peeled away. From there, the printer can expose a stencil much as they would a screen coated with liquid emulsion.
