    Abstract: PURPOSE: To manufacture a desired anti-copy film easily and precisely by separating a film web into individual copy films and folding each of the copy films into anti-copy film layers along a partition line. CONSTITUTION: When each of the opposite side surfaces of a section I corresponding to a first layer is printed with opaque or reflective, elongate coatings S1, S2 and layers are successively stacked one on another, a coating S3 is applied only onto a side surface of a section II of a second layer oppositely oriented to the first layer. When layers are successively superposed one on another, coatings S1, S2, S3 are arranged regularly and repeatedly so as to provide correct coatings. After application of coatings, a film web 6 is separated into individual anti-copy films, following which each of the anti-copy film is folded along a partition line 7, whereby a copy film ready for use can be obtained.
