“…sample preparation is known as destructive technique. The major reason behind this limitation in the field of questioned document is the limitation in use of analytical techniques preferred as non-destructive techniques 4,5 Examples of destructive technique used for examination of sequence of stroke may include application of certain chemicals which may be required for sample preparation i.e. the chemicals required for pre lifting of the sample.…”

The sequence in which the writing strokes have been executed on a paper is known as sequence of strokes. Examining the sequence of strokes can help in determining the relative age of ink which is required in various cases related to document examination including examination of wills, cheques, statements, receipts, agreements etc. The current study is focused on examining the sequence of strokes executed with a ball point pen. Video Spectral Comparator 8000 (VSC8000) has been used for the current examination. The test samples and the actual questioned documents were examined under VSC8000. It was observed that depending on the pressure through which the strokes have been executed, identification of sequence of two or more intersecting writing strokes was possible.
