Abstract: Objective To set up a method for fast identification of photocopy papers.Method Similar photocopy paper samples were analyzed by using FT-IR.The characters of the method were studied.Result Veracious and fast identification of similar photocopy papers with FT-IR in this method was feasible.Con- clusion This is a new,fast,sensitive,and veracious method of i- dentification of similar photocopy papers.It can be used to iden- tify the brand ,even the batch of similar photocopy papers,and is especially appliable to the identification of little fragments or a great many of photocopy papers.The results are repeatable.

Key words: FT-IR, photocopy paper, fast identification
