Introduction
Interpretation of the core content of the standard
DA/T 90-2022 is the first standard in the archives industry specifically for simulation and reproduction work. It has built a complete working system including key technical elements such as scanning equipment and color management software. The standard highlights three principles: original protection first, realistic restoration of form, and technical applicability.
Comparison of key technical indicators
| Technical links | Basic requirements | High-precision requirements | Detection methods |
|---|---|---|---|
| Image acquisition resolution | ≥300dpi | ≥600dpi | Spectrophotometer measurement |
| Number of color bits | 24 bits | 48 bits | ICC profile verification |
| Color difference tolerance | ΔE≤5 | ΔE≤3 | CIE Lab color space detection |
Analysis of implementation difficulties
Case: Simulation and reproduction of paper archives from the Republic of China
A certain archive needs special treatment when replicating brittle documents from the Republic of China:
1. Use a non-contact scanner (optical resolution 3200dpi)
2. Use special mounting paper to simulate the texture of the original
3. Restore faded handwriting through a 6-color pigment ink system
Analysis of standard evolution
Compared with traditional manual copying, the digital image technology system established by this standard has obvious advantages:
- Efficiency improvement: Batch processing capacity increased by 5-8 times
- Precision control: Change color difference ΔE from subjective judgment to quantitative indicators
- Traceability: Completely retain digital intermediate files
Implementation suggestions
- Establish a special team including composite talents in art, photography, and computer
- Regularly calibrate spectrophotometers and other testing equipment
- Implement a three-level backup of precious archives: "original-digital file-copy"
