ISO 10594:2006

Micrographics - Rotary camera systems - Test target for checking performance

ISO 10594:2006 specifies a test target and a method for checking the optical and mechanical performances of rotary cameras used for producing 16 mm microfilm. This test target and method can be used for evaluating the performance of cameras (e.g. before purchase to establish initial reference), acceptance tests (e.g. confirming purchase specifications after maintenance), and routine checking (e.g. weekly or monthly). NOTE The characteristics of a rotary camera are also indicated.

Overview

ISO 10594:2006 - Micrographics - Rotary camera systems - Test target for checking performance - defines a standardized test target and method to check the optical and mechanical performance of rotary cameras used to produce 16 mm microfilm. The standard is intended for initial evaluation (e.g., before purchase), acceptance testing after maintenance, and routine checks (weekly/monthly). Annex A describes characteristic issues specific to rotary cameras (synchronization, focus sensitivity, maintenance needs).

Key topics and technical requirements

• Test target construction
  • Positive-appearing on a white opaque base (visual diffuse reflection density ≤ 0.08; opacity > 85%).
  • Minimum contrast (visual diffuse density difference) between base and printed features: 1.3.
  • Identification text: “rotary camera test target” and certifying agent/source.
• Test target layout
  • Three double columns of ISO test-chart characters or patterns, character/pattern ranges specified.
  • Frequency ladders (examples: 1.8, 2.0, 2.5, 3.2 line pairs/mm), reference scale in millimetres, feed direction arrow, and two perpendicular lines (220 mm and 200 mm) for orthogonality and reduction-ratio checks.
• Microfilming procedure
  • Exposure setting to achieve microimage background density 1.0–1.3 (measured per ISO 5-2/5-3).
  • Feed the target in the arrow direction; film multiple passes or cut into strips if needed to cover aperture.
  • Minimum of 10 exposures for initial setup/after major repairs; fewer for routine checks.
• Evaluation and measurements
  • Use a microscope (50:1–150:1) with image-size measurement.
  • Check mechanical performance (transport synchronization, intermittent blurring).
  • Determine optical resolving power per ISO 446/ISO 3334.
  • Verify reduction ratio comparing reference line lengths on original vs. microimage.
  • Perform legibility tests on character lines.
• Record keeping
  • Use the standard data sheet to log camera, film type, reduction ratios, background density, test results and comments.

Practical applications and users

• Microfilming service providers and micrographics labs performing quality control.
• Procurement teams evaluating rotary camera performance before purchase.
• Maintenance technicians and service engineers validating repairs and acceptance tests.
• Archives, records managers, and document management professionals ensuring long-term legibility and preservation of microfilm records.
• Organizations operating high-throughput rotary microfilming lines that require routine verification of synchronization, focus, and reduction accuracy.

Related standards

• ISO 446, ISO 3334 (micrographics test charts and resolving power)
• ISO 5-2, ISO 5-3, ISO 5-4 (density measurement methods)
• ISO 2471 (opacity)
• ISO 6196 series (micrographics vocabulary)
• ISO 10550 (planetary camera test target - complementary standard)

Keywords: ISO 10594:2006, rotary camera test target, micrographics, 16 mm microfilm, resolving power, reduction ratio, legibility, mechanical performance, test procedure.

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. Each 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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. 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.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 10594 was prepared by Technical Committee ISO/TC 171, Document management applications,
Subcommittee SC 1, Quality.
This second edition cancels and replaces the first edition (ISO 10594:1997), which has been technically
revised.

Introduction
This International Standard has been prepared to provide a means of checking the quality of output of rotary
camera systems. Rotary cameras have certain characteristics that require a different form of test target from
that specified for checking planetary cameras in ISO 10550.
The processes of microfilming may result in the production of an image that is in some way inferior to that of
the original document. In order to keep such deterioration within acceptable limits, the output of the camera
needs to be checked regularly so that faults can be corrected and any necessary adjustments made.
