Randomized trial characterizes paper qualities in historical Buddhist scriptures, suggesting advancements in printing technologies.

The aim is to scientifically characterize printing papers from 13th-century Goryeo Buddhist scriptures using non-destructive methods.
Used non-destructive Fourier transform-infrared (FT-IR) spectroscopy to analyze woodblock-printed papers.
Measured thickness, basis weight, and apparent density of nine scripture pieces.
Examined surface-treatment methods via imaging and FT-IR analysis.
Most papers were made from paper mulberry bast fiber (Hanji).
Identified both untreated and treated surfaces, such as animal-glue sizing and paper calendering by pounding.
Certain scriptures demonstrated enhanced printability due to surface treatments.

Lee et al. (2026) studied this question.
