The Influence of Variation on Typewriting Identification
Ordway Hilton · The Journal of Criminal Law Criminology and Police Science · 1959
Document Examiners. The work of every typewriter reveals some varia-tion when repeated impressions of the same letters are carefully compared. Despite the fact that type-writing identification experts are familiar with this phenomenon, variation has not, as a rule, been frankly acknowledged in discussion of type-writing identification. In many ways this seems strange. All readily recognize the presence of varia-tion in a person's handwriting, but when it comes to typewriting identification they tend to ignore it. As a preliminary step in this investigation the various texts and writings on typewriting identi-fication were reviewed. For the most part little or nothing is said about typewriting variation. Osborn
