Ink examination is an important forensic task conducted by question document examiner. It is interesting to know that the composition of different brands of ink are confidential but it is possible to examine the handwriting written by different brands of ink by using destructive and non-destructive methods. This study is mainly focused on the applicability of non-destructive methods to differentiate ball point pen ink made by different manufacturer in India. We have used only non-destructive methods in this study. In experimental work, we used VSC and FTIR both are the most attractive techniques as they maintain the integrity of document. Sample ink was applied on a blank paper and observation was made at different parameters. Most of the brands can be discriminated by VSC filtered light examination. IR analysis revealed that each brand is possible to differentiate by looking their spectra. At the end of the work we are able to differentiate among most of the brands by using non-destructive methods.
