Introduction
GB/T 33713—2017 Standard Overview
This standard specifies the terms and definitions, material requirements, technical requirements, test methods and environmental conditions for process control of heat-set rotary offset printing, and is applicable to the whole process management of heat-set rotary offset printing.
Comparative Analysis of Standard Frameworks
| Standard Dimensions | GB/T 33713—2017 | ISO 12647-2:2004 | SWOP (USA) |
|---|---|---|---|
| Technical Requirements | Comprehensively specifies the process parameters and technical indicators of heat-set rotary offset printing | Focuses on the commonality of offset printing, but does not highlight the heat-set characteristics | Focuses on commercial publishing applications |
| Test Methods | Specifies in detail the measurement standards for color difference, overprint error, etc. | Provides general test methods | Emphasis on quality control processes |
| Environmental conditions | Strictly control the temperature and humidity range (23±5℃, 60±15%RH) | No specific requirements are specified | Recommended standard workshop environment |
Interpretation of material requirements
Paper technical parameter comparison table:
| Type | Basis weight (g/m²) | CIE whiteness | Glossiness (%) |
| Glossy coated paper | 60~128 | 105～135 | 55～80 |
| Matt coated paper | 60~128 | 110～135 | 20~35 |
Implementation suggestions section
Technical parameter calibration suggestions:
- Regularly calibrate the screen line number and screen angle of the printing equipment to ensure that they meet the standard requirements (the screen angle difference between the cyan, magenta and black plates should be 30°)
- It is recommended to use the PDF/X file format for data exchange to avoid color deviation caused by file format problems
- It is recommended to use the CY/T 128 method to adjust the data before printing to ensure that it is consistent with the printing conditions specified in the standard
Quality control optimization:
- Establish a regular inspection mechanism, focusing on key parameters such as color difference (△Eab), overprint error and tone value increase
- It is recommended to use ISO 13655 M0 and M1 conditions for CIELAB value measurement to ensure data accuracy
- For complex images, it is recommended to use an online measurement and control system to monitor the printing process in real time
