The Royal Library of Denmark holds collections of handwritten letters and records from the former Danish colonies in Tranquebar, India (1620-1845) and St. Croix, the West Indies (1672-1917). Many of these documents are faded and decayed by age, moisture, and bugs.
In 2017 samples from the collections were captured using Multispectral Imaging and the results included the recovery of readability and the appearance of watermarks in the paper.
