Abstract

A method is described to maintain the width of vertical lines in a character constant when the horizontal resolution of a character is changed electronically. This method relates to printers that print characters based on character raster patterns. More specifically, this method deals with the processing that is performed to reduce the horizontal resolution of the character raster patterns without significantly reducing the print quality of the modified characters. The term "stroke" is used to describe the imaginary brush stroke that is used to "paint" the lines that make up a character when the artwork for the character is created. The pel (print element) pattern for the character is based on this original artwork.
