MODELING OF PRESSURE IN WRITING AND THE POSSIBILITY OF EVALUATING THE PRESSURE CHARACTERISTICS OF HANDWRITING

Abstract

The article considers a physical-and-mechanical model of the writing process using a writing device with a ball element. The purpose of developing this model is to develop the theory of pressure in judicial handwriting, as well as to evaluate the pressure characteristics of handwriting, which are manifested primarily in the width and depth of handwritten strokes. At the same time, it is concluded that it is necessary to study handwriting objects from the perspective of their three-dimensionality, since it is the pressing characteristics of handwriting in this three-dimensionality that manifest themselves and allow for the further development of three-dimensional models of the writing process and the use of appropriate tools (technologies) to increase the reliability and objectivity of expert conclusions in the production of forensic handwriting examinations. The development of a physical-and-mechanical model reflecting the writing process is a very urgent task in judicial handwriting, since writing devices with a ball element (ballpoint pens, gel pens, roller pens) are currently used in writing much more often than others. The author offers a new definition of the concept of "pressure when writing", which takes into account both the physics of the writing process and its result according to the theory of trace formation adopted in traceology. He also demonstrated examples of calculating the pressure parameters manifested in the relief of handwritten strokes, outlined new approaches to the analysis and evaluation of the pressure characteristics of handwriting.
