  • Patent number: 4544430
    Abstract: Legends are built up from dry transfers in the usual way but on an intermediate carrier. Water or other liquid is applied to the rear surface of the intermediate carrier and an adhesive tape or sheet applied over the letters. The adhesive tape is then peeled away from the intermediate carrier bearing the letters which can then be adhered where desired, e.g. on a background scene or in a frame, using their own adhesive, whereafter the adhesive tape or sheet is peeled away to leave the letters looking as though they had been transferred there in the usual way.
