Apparatus for marking the edge of a film particularly for identifying head and tail sections of film strips joined by a splice comprising a holder with a channel-like film guide in which the film may be inserted for longitudinal movement and a hole for a pen-type applicator positioned so that as the film is moved lengthwise through the guide one edge of the film is wiped across the tip of the applicator so that a continuous ink or dye mark is applied to the film edge which appears as a ring on the side of the film when it is wound onto a reel.
