ISO 732:2000 pdf download – Photography — 120-size and 220-size films — Dimensions.
1 Scope This International Standard provides specifications for ? dimensions of 1 20-size and 220-size films and of the spools common to both, ? dimensions of the backing paper for 1 20-size film and the leader and trailer paper for 220-size film, as well as the placement of the paster tape used for attaching these papers to the films, ? minimum length of film required in front of the leading edge of the first image and behind the trailing edge of the last image, and ? markings on the backing paper and the trailer-paper for identification of the intended photofinishing process. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC maintain registers of currently valid International Standards.

6 Identification of exposed rolls 6.1 General A uniform and distinctive contrasting standard pattern shall appear along both edges of the trailing (exposed) end of the backing paper (1 20-size) or the trailer paper (220-size) of colour roll films in order to identify the intended photofinishing process. This shall be of sufficient length to cover at least the entire outer lap of the paper. Films for a black-and-white process shall not have these standard patterns along the trailing edges. The pattern shall be additional to any other identifying printing included by the manufacturer. The manufacturer’s own marking shall be so arranged as not to obscure the identifying patterns. 6.2 Colour negative process The pattern for the colour negative process shall be a series of rectangles located along each slit edge. It is intended that there be sufficient rectangles to allow photofinishing personnel to distinguish them easily before film processing. A manufacturer may remove some of the rectangles in order to substitute additional information such as the type of processing chemistry intended. Information regarding the appearance of these symbols is given in A.3 of annex A (see Figure A.1 ).
