- Title
A TEST PLATE FOR PROPORTIONAL SPACING TYPEWRITER EXAMINATION.
- Authors
Hilton, Ordway
- Abstract
This article addresses several issues pertaining to identifying typewriting in police investigation as of July 1956. The problem of identifying typewriting has become somewhat more complicated through the introduction by the International Business Machine Corp. of a proportional spacing typewriter. The machine, marketed as their Executive Model, prepares typewriting which closely resembles printing. In contrast to the conventional machine on which each letter occupies the same horizontal space, for example 1/10 of an inch for pica type, the proportional spacing machine's letters space in a similar way to printed type. For example, the i takes up less space than the a, and lower case letters are generally narrower than capitals. For identification questions involving proportional spacing typewriting there is a need for ruled test plates to handle two problems. One involves malalignment, that is letters printing too far to the right or left or above or below the base line. A trained examiner can often spot improperly aligned letters in pica typewriting without the aid of a test plate, but in proportional spacing typewriting with the tolerances much smaller, this is not so easy. The second problem concerns a document typewritten at two different times, for example one in which a paragraph has been added after execution.
