Full title and description

ISO 1785:1983 — Cinematography — Printed 8 mm, Type S, image area on 16 mm motion‑picture film perforated 8 mm, Type S — Position and dimensions.
Русский вариант наименование: «Стандарт ISO 1785-1983 — Кинематография — Печатная область изображения 8 мм, тип S, на 16 мм киноплёнке с перфорацией 8 мм, тип S — Положение и размеры».

Abstract

This standard specifies the position and dimensional requirements for a printed 8 mm (Type S) image area when incorporated on 16 mm motion‑picture film that uses 8 mm Type S perforation. It defines the reference lines, co‑ordinates, tolerances and illustrative drawings needed to ensure consistent placement and size of the 8 mm printed image on 16 mm stock for production, printing and projection interoperability.

General information

• Status: Published (original publication: 1983).
• Publication date: 1983.
• Publisher: International Organization for Standardization (ISO); Russian text edition typically issued as Ст ISO 1785‑1983 for Russian readers.
• ICS / categories: 37.060.10 — Cinematography / Motion‑picture film formats and equipment.
• Edition / version: First edition (1983).
• Number of pages: Typically a short technical specification (small‑format ISO cinematography standards — approximately 3–8 pages). (Exact page count may vary by publisher copy/translation.)

Scope

The standard applies to the geometric layout of a printed 8 mm Type S image area when that image is printed onto 16 mm film stock which is perforated with 8 mm Type S perforations. It covers reference lines, image‑area co‑ordinates, dimensioning conventions and permissible tolerances necessary for manufacture, printing, optical sound and projection compatibility. It does not cover photographic emulsion characteristics, exposure, processing chemistry or projection equipment specifications beyond positional/dimensional compatibility.

Key topics and requirements

• Definition of the printed 8 mm (Type S) image area and its nominal dimensions when placed on 16 mm film.
• Reference lines and datum used to locate the image area relative to 8 mm Type S perforations.
• Dimensional tolerances for lateral and longitudinal placement to ensure consistent framing and to avoid interference with perforations and optical‑sound tracks.
• Illustrative drawings showing position, orientation and measurement points for quality control.
• Requirements for marking and labelling conventions where applicable (e.g., frame numbering and edge codes relevant to positioning).
• Guidance for printers, laboratories and equipment manufacturers on maintaining interoperability between 8 mm printed material and 16 mm carriers.

Typical use and users

Users include film laboratories (printing and duplication), motion‑picture equipment manufacturers, archivists, restoration specialists, film‑processing facilities, standards bodies and technical librarians. Typical applications are preparation of printed 8 mm material on 16 mm carriers for distribution or projection, ensuring consistent framing in mixed‑format productions, and specifying tolerances for manufacturing and quality control of printed film stock.

Related standards

This standard belongs to the family of ISO cinematography standards and is commonly used alongside related standards that define film formats, projection and camera usage. Closely related items include ISO standards that cover 8 mm Type S projector usage, camera specifications and other printed image‑area definitions for various film formats and perforation types.

FAQ

Q: What is this standard?

A: ISO 1785:1983 specifies the position and dimensions of a printed 8 mm (Type S) image area when placed on 16 mm motion‑picture film with 8 mm Type S perforations. A Russian published edition is commonly referenced as Ст ISO 1785‑1983.

Q: What does it cover?

A: It covers geometric layout, reference datums, co‑ordinates, drawing illustrations and dimensional tolerances needed to place and control the printed 8 mm image area on 16 mm film stock. It does not address emulsion chemistry, exposure or projector mechanical design beyond placement compatibility.

Q: Who typically uses it?

A: Film laboratories, printing houses, projection and camera equipment manufacturers, archivists and restoration professionals use it to ensure consistent image placement and interoperability between film formats and printing processes.

Q: Is it current or superseded?

A: The document is the 1983 ISO publication. Some historical cinematography standards have been confirmed, revised or withdrawn since the 1980s; availability of a more recent revision or withdrawal should be checked with ISO or the relevant national standards body. For procurement or compliance, always verify the current status with the issuing body.

Q: Is it part of a series?

A: Yes — it is part of a set of ISO standards addressing film formats, projector and camera usage and printed image areas (other nearby ISO numbers from the same subject group address related 8 mm/16 mm projector and camera specifications and image‑area definitions).

Q: What are the key keywords?

A: Key keywords are: 8 mm Type S, 16 mm film, printed image area, perforation Type S, image position, dimensional tolerances, cinematography, film printing, Ст ISO 1785‑1983.
