Discrimination and Identification of Handwriting
Handwriting examiners are frequently involved in the examination of writing in other languages and alphabets in which there is remarkable variety, not confined simply to the formation of characters, but variation also in the number of characters employed. Similar to fingerprint identification, handwriting identification presupposes that handwriting is unique to the individual. Roy Huber and A. M. Headrick chose the term discriminating elements as the most appropriate expression to use in reference to the aspects of writings that are involved in their identification or differentiation. Elements of execution are the aspects of writing that are the less obvious, more subtle elements that frequently require the microscope or other technical assistance to fully assess. Handwritten interlineations in typewritten text usually eliminate consideration of the consistency of the inks involved, unless there are other handwritten materials or signatures on the document with which a comparison may be made.
