Introduction
GB/T 33244-2016 Standard Overview
This standard specifies the quality requirements and inspection methods for digital hard proofing systems in detail, and is applicable to digital hard proofing systems based on electrostatic imaging and inkjet imaging technologies. The standard specifies various indicators from substrate characteristics to output effects, and provides detailed test methods.
Key technologies of digital hard proofing system
| Technical dimensions | Requirements for electrostatic imaging system | Requirements for inkjet imaging system |
|---|---|---|
| Color reproduction accuracy | Average color difference in CIELAB color space ≤4.0 | Average color difference in CIELAB color space ≤2.0 |
| Output resolution | The line pairs that can be clearly distinguished in the test sample are not less than 6.3l/mm | Same as above |
| Stability requirements | CIELAB color difference within 24 hours ≤2.0 | CIELAB color difference ≤1.0 within 24 hours |
Explanation of professional terms and practical application cases
Digital hard proofing system:A system that uses prepress data and digital hard copy technology to simulate the visual effects of printed products. For example, in packaging printing, digital hard proofing can verify whether the ink overprinting effect meets expectations.
Background of standard formulation
With the popularization of digital technology in the printing field, digital hard proofing systems have become an important tool for evaluating printing quality. The formulation of this standard aims to unify industry technical requirements and ensure that the output of equipment from different manufacturers is comparable and consistent.
Implementation recommendations
- Hardware selection:Select electrostatic imaging or inkjet imaging equipment that meets the requirements of the standard to ensure that its resolution and color accuracy meet the requirements.
- Environmental control:Set the operating environment according to the temperature and humidity conditions required by the standard (23±5℃, 50±10% RH) to avoid external interference factors affecting the test results.
- Regular calibration:It is recommended to perform a comprehensive calibration of the equipment every three months to ensure that the long-term stability meets the requirements.
