Principal edition
The most important information and edition of the newspaper to be identified. 3.2
Target
The document containing the bibliographic and technical information of the newspaper to be photographed, including the test chart. 4 Microfilm
For long-term preservation, black and white silver salt-gelatin ester film base films that comply with ISO 6148:2001 and ISO 18906:2000 should be used.
5 Reduction ratio and image arrangement
5.1 Overview
The reduction ratio should comply with the provisions of GB/T16573--2008. Note: The reduction ratio of newspapers is usually 1:14 to 1124. 5.2 Reduction ratios for small pages and sub-frames
Pages smaller than the normal page of the newspaper, such as newspaper inserts and folds, should be photographed at the same reduction ratio as the rest of the newspaper, or at a lower reduction ratio for better clarity. If the insert or fold is so large that a higher reduction ratio would affect the clarity of the image arrangement 1A (see Figure 2), it should be photographed in sub-frames. The order of sub-frames should be from left to right and from top to bottom, as shown in Figure 1 (except for Oriental languages ​​written from right to left), and adjacent parts should overlap by at least 25 mm. The reduction ratio used should ensure the appropriate number of sub-frames and the amount of overlap. When changing the reduction ratio and restoring the original reduction ratio, the reduction ratio plate with a scale should be photographed in the previous frame. I
Figure 1 Order of sub-frames
5.3 Image arrangement
Figure 2 shows four recommended image arrangements for 35 mm microfilm. 2
Usually, dimension b is limited by the image area of ​​the newspaper being photographed, and dimension a should not exceed 31.75mm. The minimum dimension c between image information should be 2mm.
The image should be located in the center of the frame.
Changeable
1A and 1B arrangements are single-page shots.
2A and 2B arrangements are double-page shots,
Changeable

Changeable
GB/T25072—2010
1A and 2A arrangements, for text read from left to right, the text lines are perpendicular to the long axis of the film; for text read from right to left, the text lines are parallel to the long axis of the film. For 1B and 2B, the text lines are parallel to the long axis of the film when the text is read from left to right; for text read from right to left, the text lines are perpendicular to the long axis of the film. Figure 2 Image arrangement on microfilm
5.4 Page order
For newspapers with text read from right to left and other newspapers that are different from the usual Western text arrangement order, the page arrangement order should conform to the reading order. The image on the film can be easily made to reflect the text order by rotating and positioning the camera head. The text lines are parallel to the long axis of the film for 1B and 2B arrangement or perpendicular to the long axis of the film for 1A and 2A, see Figure 3. Text read from left to right

6.1 Transparencies
Except for the film runout, each 35mm microfilm reel should have 500+mm of unexposed film at the head and tail.
Note: Repeated information labels at the tail are arranged in reverse order to allow the film to wrap around to the short end of the tail. This process saves work time and reduces copy damage. GB/T25072—2010
Archive test area
If the archived microfilm needs to be tested for thiosulfate residue, a minimum density (transparent) microfilm of not less than 300 mm should be left outside the header and trailer of each disc as specified in 6.1. >
Photography requirements
7.1 Transparent treatment
The photographing of transparent newspapers should be done in an appropriate manner to minimize the backside transparency. 2 Lighting
Newspapers should be placed on a uniformly illuminated manuscript table, even for bound newspapers. Bound newspapers should use an adjustable book support table. Check and adjust the lighting uniformity according to the equipment manufacturer's instructions. 7.3 Background plate
To facilitate the digital scanning of microfilms, it is advisable to use a matte black background plate when photographing, see GB/T16573-2008.8
Document arrangement
8.1 Chronological order
Photographs should be taken in the order of the year, month and day of the newspaper. Divide the microfilms if there are plans and conditions that allow the catalog. The microfilms of a unit of a newspaper should not be divided into two reels of film. Usually, the microfilms are divided according to the following publication cycles: ten days, half a month or a whole month;
: two, three, four or six months;
one year or several years.
Examples of sub-disks are as follows,
-·-March 1-March (10) 15; ----September 1--October 31;
:-January 1, 1956-December 31, 1957 (if several years are photographed together). 8.2 Photographing of originals and copies
Originals include all the main issues and supplements. Or special issues should be considered for microfilming in their entirety, and when microfilming other attachments are attached, they should be photographed directly after the original of each day or in its own chronological order. Numbered or lettered sections should be photographed in order, followed by unnumbered sections and copies. Copy pages forming a complete part of the newspaper should be photographed in their original position.
