Effects of Writing Instruments on Handwriting Details
Ordway Hilton · Journal of Forensic Sciences · 1984
Abstract A study was made of handwriting specimens prepared with different classes of common, modern day writing instruments. It was found that the basic characteristics of some types of pens can suppress certain writing details. It is not true of every class of writing instrument, however, since some different classes of pens produce comparable writing strokes. These latter specimens can be easily compared but in the former case the examiner must recognize the kind of variables that can be introduced by the pen in order to avert erroneous opinions.
