Some standard content:
GB/T17155—1997 This standard is equivalent to the international standard IS012635:1996 Printing technology - offset printing plate: - size>. In the process of formulating this standard, according to the actual situation of my country and taking into account the connection with the aluminum plate base standard of my country, the allowable error was appropriately adjusted. The test conditions in IS12635.1996 require the standard environment for inspection and/or testing in accordance with 150) 554:76. For the convenience of use, in the process of compiling this standard, it is placed at the end of the standard as an appendix. Appendix A of this standard Appendix to this standard This standard was proposed and approved by the National Technical Committee for Printing Standardization. The drafting unit of this standard: China Institute of Printing Science and Technology. The drafters of this standard are Yue Demao and Zhang Hong. GB/T 17155—1997 ISO Foreword ISO (International Organization for Standardization) is a worldwide specialized organization for standardization composed of national standardization bodies (ISO member bodies). The work of formulating international standards is usually completed by ISO technical committees. Each member body has the right to participate in the work of the committee if it is interested in the standard items confirmed by the ISO technical committee. International organizations (official or unofficial) that maintain contact with ISO () can also participate in the relevant work. ISO maintains a close cooperative relationship with the International Electrotechnical Commission (IEC) in the field of electrotechnical standardization. The international standard draft proposed by the technical committee is submitted to each member body for voting. The international standard can only be formally passed after obtaining the consent of at least 75% of the member bodies who have signed and voted. International Standard IS012635 was formulated by ISO/TC130 Printing Technical Committee. B/T17155-1997 This standard is the first step in the national regulation of offset printing plate parameters. Not all current plate sizes are included in this standard. This standard only contains provisions on plate sizes and three recommended hole models. Its purpose is to limit the width range of plates, unify plate production, printing press manufacturing, and product specifications and communication between printing presses. 1 Scope National Standard of the People's Republic of China bzxZ.net Offset Printing Plate Dimensions Plates for offset Printing-DimensionsGB/T 17155 egv IS0 12635:1996(E) This standard specifies the definition of width, length and dimensions of offset printing plates (hereinafter referred to as "printing plates") and the hole shape, nomenclature and designation of the plates: This standard is applicable to metal plates. Plates made of other materials may also be implemented by reference. This standard is not applicable to plates provided in roll form. 2 Definitions This standard recommends the following definitions. 2.1 Plate width (us) Dimension of the plate side parallel to the axis of the roller (fastening). 2.2 Plate length (1) Dimension of the side perpendicular to the plate width (side along the roller periphery). 2.3 Plate thickness (s) Nominal thickness of the coated plate 3 Technical conditions 3.1 Test piece The measured value shall be measured under the test environment specified in Appendix A. 3.2 Dimensions 3.2.1 Plate dimensions When measuring the plate under the conditions specified in Section 3.1, the plate width, plate length and plate thickness shall be as shown in Table 1. According to the provisions of Table 2, the size limit deviations of the length and width of the printing plate given in Table 1 are based on a perfect shaped printing plate. Figure 1 shows the standard size of a printing plate (solid line) and the rectangle (deer line) that meets the positive and negative limit deviations. The actual shape of the printing plate with vertical deviation should completely cover the smaller rectangle in Figure 1 and cannot exceed the larger rectangle.

This section only applies to small offset printing plates with a size of less than 0.15mm and 1mm. Its size and limit deviation should comply with the provisions of Figures 2 and 3. Figure 3 shows an optional structure. Figure 2 is a schematic diagram of a printing plate with a round hole with a diameter of 4.5mm. The × part in Figure 2 is enlarged as follows (1) Long hole (5.5mm×11mm) (2) Round hole (4, 5rmm) (3) Round hole (4mm) J0. 21: = 0. 75 GB/F 17155 Figure 3 Position and shape of the holes in the printing plate The center distance of each hole shall not deviate from its designated position by more than 0.50mm. 1.:c.21 The two rows of holes punched must be parallel to each other and parallel to the bottom of the printing plate: the holes in the two rows must be aligned in pairs, and the position error of each pair of holes must be less than 0.50mm (see Figure 4). The distance between the printing plate and the roller axis and the hole edge must meet the specifications of the manufacturer's products, with an error of ±0.50mm. The position of the last hole in each row shall comply with this regulation, and the position of the hole end in the other row shall meet the vertical requirements.
