Abstract
A practical kerning method and electronic typo-graphic/editing apparatus which is capable of arranging characters such that two characters do not come too close to each other across a small character or sign included in a character string. In positioning an object character with a space reduction relative to an immediately preceding character, a space (character space) between the first character and the third character of three characters, for example, is determined after the three characters are arranged with successive space reductions. This first to third character facing space is checked to see if it is smaller than a reference space. When the first to third character facing space is smaller than the reference space, a correction is made to at least one of a space reduction amount for the second character and a space reduction amount for the third character. An excessive closeness between the first and third characters is prevented by slightly diminishing the space reduction amount for at least one character.
