Jodskanning

Jodskanning is a method used in various fields, particularly in historical research and genealogical studies, to analyze and preserve documents that have been affected by ink degradation. The term itself is a compound, with "jod" referring to iodine, a chemical that was a common component in older inks. Over time, inks containing iodine can fade, become brittle, or even eat through the paper they are written on, making the text difficult or impossible to read.

Jodskanning involves using specialized imaging techniques to capture the faint traces of ink that remain. This often utilizes infrared or ultraviolet light, which can reveal pigments or chemical residues that are invisible to the naked eye. By carefully adjusting the light spectrum and exposure, it's possible to make the faded or damaged text legible again. The process is non-destructive, meaning it preserves the original document while creating a readable digital or photographic copy.

The primary goal of jodskanning is to make historical records accessible for study and to prevent the loss of valuable information. This technique has proven invaluable for deciphering wills, letters, land deeds, and other documents that are crucial for understanding past events and family histories. Researchers can then use these enhanced images to transcribe texts, verify facts, and build a more complete picture of the past without risking further damage to the fragile originals.
