The work of preparing International Stan
13、dards 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 t
14、ake 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
15、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 possibil
16、ity 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
17、second edition cancels and replaces the first edition (ISO 6199:1991), which has been technically revised.

18、le a camera operator to produce microfilm of appropriate quality of presentation and legibility, capable of yielding scanned images of acceptable quality. This International Standard specifies methods for microfilming documents on 16 mm and 35 mm silver-gelatin microfilm, including orientation of im
19、ages on microfilm, use of non-image areas and information required to facilitate identification of the microfilm. This International Standard applies to microfilming using rotary and planetary cameras. This International Standard does not apply to the filming of technical drawings, maps and plans an
20、d newspapers, for which specific International Standards exist 1-3. 2 Normative references The following referenced documents are indispensable for the application of this document.

25、 and the leading edge of the following microimage 3.2 scanning microfilm microfilm intended to be used for scanner input 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
26、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 do
27、cuments 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 pl

31、tation of the text on the original page, and the image orientation of the opposite row (back) is controlled by the image orientation of the above mentioned row. NOTE 2 The duo duplex format is used primarily in banking applications. aFront and back of first document bAscending order cFirst (or last)

Where simplex format, vertical mode (cine) is used, the microimages should b
33、e 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
34、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 shal
35、l 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
36、 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
37、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 lead
38、ing 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 t
39、o 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 b
40、e microfilmed. Where possible, horizontal mode should be used. BS ISO 6199:20056 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. N
41、OTE 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
42、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
43、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.

Figure 2 Channels provided for document marks (blips) and optical code format BS ISO 6199:200575.9.3 Simplex format using planetary cameras Simplex format is also used with planetar
45、y 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 ac
46、tual 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. Table 3 Planeta
