Overview
ISO 3026:1992 specifies the position and dimensions of the printed 8 mm Type S image area when produced by optical or contact printing onto 35 mm motion‑picture film perforated 8 mm Type S (pitch variants 2R-4.227 (1664) or 5R-4.234 (1667)). The standard defines how the image area is located relative to a row of perforations that is discarded after slitting; this discarded row contains a wider perforation customarily used for lateral registration. Annex A gives informative guidance on using a registration (stop) device for prints made with step printers.
Key topics and technical requirements
- Scope: Applies to negative, intermediate or positive prints produced on 35 mm film perforated 8 mm Type S.
- Image referencing: Image dimensions and positions are referenced to the row of perforations removed after slitting; this ensures consistent lateral registration.
- Registration spacing: A reference lateral registration dimension of 7.9 mm (0.311 in) is used, measured between the positioning perforation and the horizontal axis of the produced 8 mm image.
- Dimension set: The standard provides a table (Table 1) and figure defining dimensional callouts (A–L and R) in both metric and inch units for accurate printing and verification.
- Projector alignment: The vertical reference (cote H) is tied to “perforation minus 2” because that perforation aligns with the projector positioning used for direct front projection (see ISO 1781).
- Informative annexes: Annex A - use of stop devices on alternative printers; Annex B - bibliographic references.
Practical applications and users
ISO 3026:1992 is intended for professionals and organizations involved in film production, printing and archiving, including:
- Film laboratories performing optical contact or step printing of 8 mm Type S images onto 35 mm stock
- Post‑production and finishing houses ensuring printed frames meet positional tolerances
- Equipment designers (tireuses, step printers, registration devices) and projector manufacturers needing compatibility with projector positioning standards
- Film restorers and archives validating historic prints and remastering workflows
- Quality assurance and standards compliance teams implementing consistent image registration across prints
Using ISO 3026 helps ensure consistent image placement, reliable lateral registration, and projector compatibility - essential for projection, duplication and long‑term preservation of 8 mm Type S material.

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, govern-
mental and non-governmental, in liaison with ISO, also take patt 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 Inter-
national Standard requires approval by at least 75 % of the member
bodies casting a vote.
International Standard ISO 3026 was prepared by Technical Committee
ISO/TC 36, Cinematography.
This second edition cancels and replaces the fit-st edition
(ISO 3026:1975), of which it constitutes a minor revision.

Avant-propos
L’ISO (Organisation internationale de normalisation) est une fédération
mondiale d’organismes nationaux de normalisation (comités membres
de I’ISO). L’élaboration des Normes internationales est en général
confiée aux comités techniques de I’ISO. Chaque comité membre inté-
ressé par une étude a le droit de faire partie du comité technique créé
à cet effet. Les organisations internationales, gouvernementales et non
gouvernementales, en liaison avec I’ISO participent également aux tra-
vaux. L’ISO collabore étroitement avec la Commission électrotechnique
internationale (CEI) en ce qui concerne la normalisation électrotech-
nique.
Les projets de Normes internationales adoptés par les comités techni-
ques sont soumis aux comités membres pour vote. Leur publication
comme Normes internationales requiert l’approbation de 75 % au moins
des comités membres votants.
La Norme internationale ISO 3026 a été élaborée par le comité techni-
que ISO/TC 36, Cinématographie.
Cette deuxième édition annule et remplace la première édition
