In addition to the content of 1S03272-1:1S83, it also contains more requirements that meet the current situation in my country. This standard has made the following logical modifications::!

) the decimal point "" is used as an escape sign for the decimal point. This standard is made for the purpose of making maps. This standard supplements G15311954.13T3911S03272-3:1975. Select a few standards that are not only applicable to "technical grids:" but also to: maps. However, due to the average medical front line and the continued approval of the technology, the reduction rate of the technical map group is not suitable for the scope of application: the six standards were issued by the National Document Imaging Technology Standardization Technical Committee (TSC) from the beginning of the year, and the National Archives Science and Technology Research Institute. The main drafters of this standard are: Ling Zhuhuo, Li Jian, and Youhui. This standard is the last published.

A map with geographical features printed on a non-color medium on a white background. 4 Basic requirements
4.1 The roll-type microfilm
should be 35mm box-type film in accordance with the requirements of GB/89391958. 4.2 The quality
of the film should be in accordance with the requirements of GB/38980"1998: 4.3 The card bottom should be in accordance with the specifications of S032731075. 5 Microfilming
5. 1 Reduction ratio
The frame rate should be 124, 1:1.2, 7:15, 1:10 or 1.7.5. The passband should be selected to fit the entire map in one frame of 35mm film. When you use the ratio, in order to ensure the image clarity, the optical level of the original material described in GB/165-3-1996 should be deducted.
5.2 Resolution
When testing in accordance with the GB/18989 regulations, in order to ensure that all information is recorded, for an appropriate generation and reduction ratio, all the frequency products should be tested according to the requirements of the "special test" shown in Table 1 or the detailed requirements of the No. 2 test. Table 1 Interpretation requirements
6 Test standard plate
No. 1 National Trial
No. 2 Figure
Issued film
Should be made on the first batch of Hong Kong-style film, with a low shrinkage ratio (for example, in the case of 35mm film, a shrinkage ratio of 1:13> is used to shoot the test standard (see Figure 1). In the film winding path, the standard plate should be connected to each shrinkage ratio used, or 4 The test standard plate should be shot every time the shrinkage ratio is changed.
The test standard plate should include the following shooting characteristics and be arranged according to the format shown in Figure 1. If there are ten similar common test images:
The centering symbol and format cutting symbol for one shrinkage ratio are: KAN KAca
GE/T 1873C--2002
The reflectivity rating should be no less than 15cm×150mm, no gloss, the reflectivity is neutral, the reflectivity is 5c%, the reflectivity is neutral, the reflectivity is 5c%, the reflectivity is neutral.The test strip should be compared with the scene, and the shadow length on the blackboard should be expanded into a measurement image. The test strip should be placed on the test card, and the image should be taken at the beginning of the film: each type of emissivity can be measured with a test mark, or several groups of staggered test marks can be cut together to form a test mark. The symmetrical and orthogonal cross grid is used to divide the length of the film into ten squares. The center of the cross is the most accurate positioning point, and the distance error between two adjacent positioning points is not more than 1%. In addition, the error of the length of any sentence along the grid and the nominal size is not more than .5%. The density of the light test mark is set at 1.0-1.2 after 20%. The resolution test library on the entire bill should be checked under the microscope, the currency number test chart is GR18t05---2351), the magnification of the microscope should be between 50, 1~60:1, and the No. 2 special test is used (see G/T6161.1991). The microscope magnification should be between 5~1 times to be able to distinguish the logarithmic value of each waterline! The mark of the center symbol can be recorded in the figure: the test standard board
