Abstract

The presently disclosed concept is a method of producing Alpha-Numeric Raised Prints (ANRP) for the blind. Xerographic prints, character height of 1/2 inch, are produced in the normal manner and developed with as dense a toner layer as possible. The visible image is then partially vapor fused and cascaded with 100-125 micron diameter beads of a plastic having a low melting point. The beads are then remelted to provide a permanent fixed raised surface,
