Zusammenfassung:A method and apparatus for providing erasable relief images including providing a face surface formed of a temperature sensitive shape memory material. The face surface may be selectively heated to cause the shape memory material to displace and form a predetermined relief image. Alternatively, the shape memory material may be selectively engaged with die elements to form a predetermined relief image. The relief image may be erased by heating the face surface to thereby cause the shape memory material to return to a uniform surface contour, or to soften the shape material sufficiently for it to be engaged and compressed to a predetermined uniform configuration by an erasing element.
