Coloured signs are produced by imaging a sign legend on to a temporary carrier sheet using xerographic toner, the temporary sheet being fed through the normal paper feed of a xerographic photocopying machine. The toner image is coloured using a heat transfer foil. The coloured toner image is then adhered to a thermoplastic coating on the rear surface of a transparent or translucent sign sheet and the carrier sheet stripped away. The legend may be provided with an appropriate background, e.g. by spray painting subsequently. |
