Abstract
A set of characters is provided wherein each character is formed by arranging a number of relatively small like characters in a pattern that presents a filled-in outline of the character. Each of the small like characters are printed by a thermographic process to provide a character which protrudes slightly from the media surface thus providing tactile feedback when the character is touched or traced with a finger.
