Standard insertable legend modules are an
economical way to create your own keyboard

any legend, and replace the snap-on cap.
The typestyle chart shows the style and the
approximate limitations of Grayhill's standard
type. However, limitations differ with the surface
to be printed and the actual characters to be
used. If your legend exceeds the chart limits,
contact Grayhill for more information. Unless
specified, black legends are printed on white
