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 6199 was prepared by Technical Committee ISO/TC 171, Document management applications,
Subcommittee SC 2, Application issues.
This second edition cancels and replaces the first edition (ISO 6199:1991), which has been technically revised.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 6196 and the following apply.
3.1
inter-image gap
inter-frame gap
distance, measured along the long edge of a roll microfilm, between the trailing edge of one microimage and
the leading edge of the following microimage
3.2

4 Preparation of documents
Documents to be microfilmed shall be examined carefully, defects remedied where appropriate, foreign bodies
(e.g. fasteners) removed and pages arranged in the required order.
Documents to be microfilmed shall be examined to ensure that their dimensions are within those acceptable to
the microfilming system.
Appropriate targets shall be added to each batch of documents during the preparation stage.
Annex A gives more details on the preparation of documents prior to microfilming.
5 Conditions of microfilming
5.1 Raw-stock microfilm
Raw-stock microfilm shall comply with the requirements of ISO 6148 and ISO 18906.
5.2 Formats and orientation
5.2.1 Formats
The formats commonly used in roll microfilm are shown in Figure 1.
The dimensions for the placement of the microimages on the film are listed in Table 1.

5.2.2 Orientation
Where microimages are recorded in simplex format, horizontal mode (comic), orientations 1B and 2B of
Figure 1 shall be used. Where simplex format, vertical mode (cine) is used, the microimages should be
oriented as shown in 1A and 2A of Figure 1.
The orientation of microimages for filming in duplex, duo and combination duo-duplex formats is also shown in
Figure 1.
5.3 Roll film coding
Microimages may be coded so that individual microimages or series of microimages can be easily located.
Examples of coding systems are specified in ISO 11962.
5.4 Frame numbering
Where frame numbers are used, they shall not appear within the microimage frame area. They may appear
towards either edge of the microfilm, or within the inter-image gap, offset towards the top or bottom of the gap.
Frame numbers shall not exceed 2 mm in height, measured on the microfilm.
The positioning of the frame numbers shall remain consistent within a roll of microfilm.
See also 8.2.
5.5 Placement
Microimages shall be centrally placed across the width of the frame area, with at least 30 % of each
microimage in each half of the useable width of the microfilm.
See also 8.3.
5.6 Inter-image gap
The inter-image gap shall be as specified in Table 1.
NOTE When using scanning microfilm, this inter-image gap is crucial to the detection of the image edge (see 8.4).
5.7 Edge marker
This subclause applies to microfilming using planetary cameras only.
Where the leading edge of a document to be microfilmed is so irregular that there is no segment of this edge
that can be said to define the position of the edge unambiguously, a matt white bar of minimum width 3 mm
shall be placed on the camera baseboard, parallel to the leading edge of the microimage area, and just
touching the leading edge of the document. The length of the bar shall be sufficient to extend across the
whole width of the microimage area.
5.8 Reduction ratio
The reduction ratio and orientation selected should allow the smallest alphanumeric characters to be legible in
a distribution copy projected on a reader screen and on a hard copy made from a distribution copy.
The reduction ratio to be used shall be determined by the size of the characters, the quality of the originals,
the quality of the camera-film system, and the size of the documents to be microfilmed. Where possible,
horizontal mode should be used.

5.9 Document dimensions
5.9.1 General
The maximum height or width of a microimage that can be recorded on the usable width of the film is indicated
in Table 1 and Figure 1 for uncoded film and Figure 2 for coded film.
NOTE The maximum height or width of the document depends on the film format, the reduction ratio and the type of
camera (rotary or planetary) to be used.
5.9.2 Simplex format using rotary cameras
The side of a microimage which is parallel to the length of the film may be of any length.
Table 2 lists two of the most commonly used reduction ratios for the simplex format of uncoded film from
16 mm rotary cameras. If a microimage is close to the indicated recordable size, a higher reduction ratio shall
be used to reduce the possibility of information loss caused by skewing of the document while it is being
filmed.
NOTE The maximum dimensions of a document that can be filmed are determined by the width of the throat of the
document feeder.

5.9.3 Simplex format using planetary cameras
Simplex format is also used with planetary cameras that can have variable (or a set of fixed) reductions and a
variable frame pitch. Table 3 lists the maximum dimensions of documents usable with various reduction ratios.
For microfilming using fixed frame-pitch cameras, see Table 4 and Figure 3.
NOTE To allow for positioning errors, the actual dimensions of the documents should be less than those indicated.
For 35 mm film intended for insertion in A6 jackets as strips of three frames, the maximum frame pitch shall be
47,5 mm. Appropriate reduction ratio changes may be required to accommodate the shorter frame advance.

Caution, actual reduction ratios used in practice may be different to those indicated in this table. Relevant
measurements can be calculated by applying the reduction ratio to the image frame dimensions.

5.9.4 Simplex format coding
Simplex format is also used with microfilm that is coded along the edge with a document mark or a photo-
optical code. Coded microfilm is produced in both planetary and rotary cameras at a fixed reduction ratio. The
manufacturer of the camera will provide the maximum dimensions for documents that can be microfilmed with
the camera. To allow for positioning
