Use of typewriter characters for forms design
If the form will be duplicated the type faces available can be used to give varying degrees of emphasis.
Varityping
Special typewriters are manufactured which have a range of interchangeable type faces. If one of these is available a number of other typewriter characters can be introduced. Examples (from the Varityper range), with series numbers, are:
(a) Suitable for stencil-typing or photolitho reproduction
(b) Suitable for photolitho reproduction only
