Kern

A few types have a portion of the face letter projecting over the body, as in the letter f ; this projection is called the kern, and in combination with other letters the projecting part generally extends over the next letter, as in fe. In those combinations, wherein the kern would come in contact with another letter, compound types are cast, as in the case of ff, fi, fl, ffi, ffl.

If you need to kern anything beyond the most commonly used pairs, you can use applications software such as Adobe PageMaker to customize pairs.

Especially consider kerning if you are printing on a relatively high-resolution printer, such as a 600-dpi (dots per inch) laser printer.

Remember, the goal of kerning is to make letter pairs look natural, not necessarily to minimize letterspaces.

You should kern letter pairs when spacing between characters is too wide or too narrow.
