On the possibility of determining the writing tools used in handwritten items, by their electronic images submitted for examination

The issues of identifying diagnostic features characterizing materials and writing tools used for making manuscripts, images of which are submitted in electronic form for examination are considered in the article. The authors present a summary of the results of the experiment aimed at examining digitized records produced by the use of traditional handwriting tools, as well as manuscripts produced using handwriting tools and standard brush sets simulating traditional writing materials. A subsequent comparison which revealed features presented in this article allow the differentiation of these items.
