Abstract
A laminated web has a carrier sheet and a sign material sheet superimposed on it and a first layer of permanently tacky adhesive attaching the sign material sheet to the carrier. A second permanently tacky adhesive layer is provided on the side of the sign material sheet facing away from the base layer and is coated or is provided with a film which deadens the exposed tacky surface such that the web may be cut in an automated sign generated machine and the web weeded thereby leaving free standing characters on which the second permanently tacky adhesive can then be exposed for application onto a substrate surface.
