Documents feature in the financial, legal, business, social and personal affairs. Due to spreading of use of documents, very often spurious documents are produced for perpetuating crime like cheating, fraud misappropriation, criminal misconduct, forgery anonymous communication and violation of copyright Act. In one case, a good number of science books of class ten standards were printed and circulated for sale. Taking the advantage of huge sale, the similar books were clandestinely printed by unscrupulous trader and sold at lower rate than actual printed price. The sale of original books was thus affected and on verification the original publisher could know about the fraudulent printing of same book and selling at lower price. Subsequently the original publisher lodged a complaint to the police and both original and disputed books were seized and sent to forensic laboratory for examination. This paper deals with the examination/comparison of both types of books using FTIR and video spectral comparator (VSC) to differentiate the original and disputed one.
