Screen printing is a printing technique that uses a woven mesh (screen mesh)  to support an ink-blocking stencil. The attached stencil forms open areas of mesh that transfer ink as a sharp-edged image onto a substrate. A roller or squeegee is moved across the screen stencil, forcing or pumping ink past the threads of the woven mesh in the open areas.

Screen printing is also a stencil method of print making in which a design is imposed on a screen of silk or other fine mesh, with blank areas coated with an impermeable substance, and ink is forced through the mesh onto the printing surface. It is also known as silk screening or serigraphy.

Printing Material (Fiber Characteristics Chart)

Traditionally silk mesh was used for screen-printing, hence the name silk screening. Currently synthetic threads are commonly used in the screen printing process the most popular mesh in general use is made of polyester. There are special use mesh materials of nylon and stainless steel available to the screen printer 


Printing Meshes (Screen Meshes) Provided by Share Filtration 

Share Filtration provides most-commonly used printing mesh for most of printing applications, printing meshes from Share Filtration include: polyester monofilament printing mesh, polyester multifilament printing mesh, nylon monofilament printing mesh, nylon multifilament printing mesh, stainless steel printing mesh. For polyester printing mesh, white, yellow and black colors are available, usually polyester printing mesh in yellow are over 200 threads per inch.

Fabric Construction

Fiber Type---is an important factor when choosing a fabric suitable for your application. Common considerations are working temperature, abrasion and chemical compability, which may include the PH range of your application.

Mesh Count---is the numbder of threads per inch in the direction of warp and weft of the fabric. The mesh count is identical in both warp and weft direction for Share Filtration's woven mesh.

Thread Diameter---is specified as the diameter of the thread in microns; Yarn sizes in both warp and weft directions are the same.

Mesh Opening---is the size or space between threads. The mesh opening is the result of the combination of the mesh count and yarn size. Mesh opening will determine the size or amount of material that will pass through the fabric
