STAMP (Selective Transfer Adhesive Magnetic Process) is proposed to be used to produce raised print for tactile reading. The raised print can be produced in two steps: making a regular copy on, for example, a xerographic machine and subsequently over-coating the toned area with a coating which provides sufficient elevation and a tactily sensitive surface. Donor tape used in the STAMP process can be modified for this application. The modifications include thicker layer of coating, and incorporating additives, such as blowing agents and rigid mineral materials.
