Foreword
ISO (the International Organization for Standardization) is a worldwide
federation of national Standards bodies (ISO member bodies). The work
of preparing International Standards is normally carried out through ISO
technical committees. Esch member body interested in a subject for
which a technical committee has been established has the right to be
represented on that committee. International organizations, governmental
and non-governmental, in liaison with ISO, also take part in the work. ISO
collaborates closely with the International Electrotechnical Commission
(IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the member bodies casting
a vote.
International Standard ISO 6038 was prepared by Technical Committee
lSO/TC 36, Cinema tography.
This second edition cancels and replaces the first edition
(ISO 6038:1985), of which it constitutes a technical revision.
Annex A of this International Standard is for information only.

1) In Single negative printing, dimension C should be 7,53 mm + 0,05 mm (0,296 in & 0,002 in) to minimize the possibility
of printing of a white line. Dimension A becomes 0,70 mm (0,028 in).

1) Dimension A should not be greater than 1,02 mm (0,040 in) in the anamorphic negative in Order to minimize intrusion
of the splice in the projected image area.
2) It should be noted that Type 3 splices on anamorphic film will fall within the projected area and extra care should be
taken in making a clean splice.
