- Use 300 DPI scans to preserve the fine details within Hangul syllable blocks
- For documents with Hanja, verify Chinese character recognition alongside Hangul text
- Check for correct spacing — Korean uses spaces between words and OCR may merge or split them incorrectly
- Review similar-looking jamo pairs like ㄱ/ㅋ, ㄷ/ㅌ, ㅂ/ㅍ which are common OCR confusion points
- Straighten skewed scans to avoid misalignment of the square Hangul character grid
