Microscopic Analysis of Atypical Features of Typewritten Originals
Microscopic Analysis of Atypical Features of Typewritten Originals

Summary/Abstract: The article presents the possibilities of using microscopic examinations at high magnifications to assess whether the original records were drawn by hand or using an appropriately configured CNC machine controlled by a computer program processing data in 3D technology. Appropriate programming of the device allows for faithful reproduction of the recording, with variable pressure, which allows for forgery with extremely high precision. Records by these devices are made based on a quasi-handwritten entry made using a writing tool mounted in the machine's handle, set at an angle to the ground. The record created in this way, as an imitation of handwriting, is difficult to recognise using traditional technologies for handwriting examination. This is confirmed by the results of the above-mentioned studies. The study indicates the features of the graphic line that are visible in microscopic examination, and which may differ between handwriting and machine reproduction. Unfortunately, these are not always features specific to the analysed writing techniques, which means it is necessary to conduct further analyses using more advanced technologies. They are conducted as part of the research project codenamed “Rękopis” ["Manuscript"] financed by the National Centre for Research and Development, and this article describes one of the stages of this research
