Is a printing technique that involves passing the ink through a template or also

called mesh serving masking frame attached to a tensioned in a frame. Employed in the method

reproduction of documents and images on any material and consists of transferring ink through

gauze stretched on a frame, the ink passage is blocked in areas where there is no image using a

emulsion or varnish, leaving free the area where the ink will. The printing system is repetitive, that is,

once the first model has been achieved, printing may be repeated hundreds and even thousands of times without

losing definition. Printing technique widely used in advertising...

Screen printing is a printing technique that uses a woven mesh to support an ink-blocking stencil to receive a desired image. The attached stencil forms open areas of mesh that transfer ink or other printable materials which can be pressed through the mesh as a sharp-edged image onto a substrate. A fill blade or squeegee is moved across the screen stencil, forcing or pumping ink through the mesh openings to wet the substrate during the squeegee stroke. Basically, it is the process of using a mesh-based stencil to apply ink onto a substrate, whether it be T-shirts, posters, stickers, vinyl, wood, or other material.

Screen printing is also a stencil method of print making in which a design is imposed on a screen of polyester or other fine mesh, with blank areas coated with an impermeable substance. Ink is forced into the mesh openings by the fill blade or squeegee and onto the printing surface during the squeegee stroke. As the screen rebounds away from the substrate the ink remains on the substrate. It is also known as silk-screen,screen, serigraphy, and serigraph printing. One color is printed at a time, so several screens can be used to produce a multicoloured image or design.
