12、dization) 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
13、 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 Stan
14、dards 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 Int
15、ernational 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.

This second edition cancels and replaces the first edition (ISO 6199:1991), which has been technically revised. BS ISO 6199:2005 1 Micrographics Microfilming of documents on 16 mm
17、 and 35 mm silver-gelatin type microfilm Operating procedures 1 Scope This International Standard specifies procedures that enable a camera operator to produce microfilm of appropriate quality of presentation and legibility, capable of yielding scanned images of acceptable quality. This Internationa
18、l Standard specifies methods for microfilming documents on 16 mm and 35 mm silver-gelatin microfilm, including orientation of images on microfilm, use of non-image areas and information required to facilitate identification of the microfilm. This International Standard applies to microfilming using
19、rotary and planetary cameras. This International Standard does not apply to the filming of technical drawings, maps and plans and newspapers, for which specific International Standards exist 1-3. 2 Normative references The following referenced documents are indispensable for the application of this

24、-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 scanning microfilm microfilm intended to be used for scanner input 4 Preparation of documents Documents to be microf
25、ilmed 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 t
26、argets 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
27、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.

29、applications, this figure may change in accordance with the relevant International Standard. bFor all formats except simplex.

30、icrofilm formats BS ISO 6199:20054 NOTE 1 On the duplex format, the image orientation of one row (front) is controlled by the orientation 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 T
31、he duo duplex format is used primarily in banking applications. aFront and back of first document bAscending order cFirst (or last) document dAscending (or descending) order Figure 1 (continued) BS ISO 6199:2005 5 5.2.2 Orientation Where microimages are recorded in simplex format, horizontal mode (c
32、omic), 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
33、.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
34、 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 Plac
35、ement 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 i
36、nter-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 pos
37、ition 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
38、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 b
39、y 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. BS ISO 6199:20056 5.9 Document dimensions 5.9.1 General The maximum height or width of a microimage that
40、 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
41、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 s
42、ize, 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. Table 2 16 mm rotary mi

Table 3 lists the maximum dimensions of documents usable with various red
45、uction 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 fram
46、e pitch shall be 47,5 mm. Appropriate reduction ratio changes may be required to accommodate the shorter frame advance.
