GB/T 34689-2017 in English

1. Background and significance of the standard

GB/T 34689-2017 "Determination of the mass per unit area of the oxide layer of computer-to-plate (CTP) plates for digital printing materials" was proposed by the China Petroleum and Chemical Industry Federation, managed by the National Technical Committee for Standardization of Digital Imaging Materials and Digital Printing Materials, and drafted by Lucky Huaguang Printing Technology Co., Ltd.

2. Scope of application of the standard

This standard is mainly applicable to:

• Determination of the mass per unit area of the oxide layer of computer-to-plate (CTP) plates for digital printing materials
• Detection and quality control in related fields

3. Comparison table of standard frameworks

4. Background analysis of standard formulation

With the rapid development of digital printing technology, CTP plates are increasingly widely used in the modern printing industry. However, the quality of the oxide layer on the surface of CTP plates directly affects the printing effect and service life. Therefore, it is particularly important to formulate a unified measurement standard.

5. Technology evolution and application cases

6. Implementation recommendations

1. Instrument calibration: Ensure that the sensitivity of the analytical balance reaches $0.1\mathrm{mg}$ and calibrate it regularly.
2. Reagent preparation:Prepare the treatment solution strictly in accordance with the standard requirements, and use analytical pure reagents to ensure the accuracy of the test.
3. Operation specification:When performing chemical treatment, protective equipment must be worn, and the experimental environment must comply with the provisions of Appendix A of GB/T17155-1997.
4. Data recording:Record the test conditions, instrument model and original data in detail for easy traceability and analysis.
5. Training and guidance:Provide standardized training for operators to ensure correct understanding and implementation of standard requirements.
