Areas other than handwriting and hand printing identification are also considered in the examination of questioned documents. Ink differentiation is used to detect alterations, erasures, and material changes in documents. The physical and chemical properties of two different inks will cause differing results when examined using the alternative light sources and filtering techniques available with the VSC.

DETECTING SEQUENCE OF STROKES USING STEREOMICROSCOPE

A stereomicroscope is used by our examiner to check whether the document was signed after the text was added to the sheet of paper or whether the document was signed before the text was added to the sheet of paper. The establishment of a sequence of two crossing strokes can be done which can disclose fraud in an altered and built-up document.
