Abstract

Improved readability of low resolution character displays and printers is achieved by displaying or printing from a family of stored models from which the appearance of a word is derived. Character form and intercharacter spacing are defined by the models that consider various aspects such as adjacent characters, line leading and justification. The resulting patterns are functions of words, not of individual characters. A word model, any sequence of characters delimited by spaces, is subject to stress derived from the requirements of justification. Simple models that are a single image are invariant to justification and are transferred from storage in a single copy operation. Another model has linear springs between successive characters that permit certain character spacing to be either expanded or compressed.
