ABSTRACT:
A laminated web is used for etching characters, symbols or other shapes initially scribed in a layer of stencil sheet material including one of the layers of the web and the scribed stencil sheet is subsequently separated from the remaining web and used in an electrochemical etching process. The web is adapted to be used in an automatic sign maker wherein it is scribed on automatically as a result of instructions issued from a controller and the scribed markings are then used as a negative image in the etching process of an article surface.
