Screen printing is a printing technique that uses a woven mesh to support an ink-blocking stencil to receive a desired image. Ink is forced into the mesh openings by the squeegee and onto the printing surface during the squeegee stroke. One colour is printed at a time, so several screens can be used to produce a multicoloured image or design.
Is a dry printing method of lithography in which foils are transferred to a surface at high temperatures. In a hot stamping machine, a die is mounted and heated, with the product to be stamped placed beneath it. A metalized roll-leaf carrier is inserted between the two, and the die presses down through it. The foil used is impressed into the surface of the plastic. The dye-stamping process itself is non-polluting because the materials involved are dry. Widely used on plastic where it is a common technique in security printing.
