A method of enhancing an image (11) provided by a thermoplastic marking material on a substrate (4) which material can be thermally activated to take on adhesive properties. The method comprises bringing a transfer medium (7) into contact with the substrate (4) carrying the marking material, the transfer medium including a carrier (3) and a transferrable layer (15, 16), the transferrable layer being positioned in use between the carrier and the substrate; thermally activating the adhesive property of the marking material; and separating the carrier (13) and substrate (4) whereby areas of the transferrable layer containing the activated marking material remain on the marking material, characterised in that the transferrable layer exhibits or generates a visible pattern. |
