Graphology is used as a forensic science tool. A forensic handwriting analyst will use measuring devices, regardless of the script (whether cursive or print), to compare handwriting in terms of size, width, height and angles. The documents are enlarged using stereo microscopes and magnification equipment giving a depth of field that is helpful in studying indentations of writing.
Forensic document examination services include:-
- Identification of handwriting
- Authentication of signatures
- Comparison of typescript
- Investigation of altered documents
- Forged cheques and financial documents
- Blackmail and poison letters
- Disputed wills
- Typewriter identification
The forensic aspect of graphology skills are eenhance by ESDA (Electrostatic Development of Indented Writing Impressions) which develops indented writing impressions that are not seen with the naked eye, for example evidence of altered records, names and addresses, fingerprints etc.
