A practical guide to digitising parchment, vellum and other historic membrane documents with minimal handling risk.
What is parchment digitisation?
Parchment digitisation is the controlled imaging of documents made from animal skin, including parchment and vellum. These materials can be highly significant and physically complex, requiring a workflow designed around the object.
Why is parchment different from paper?
Parchment is a skin-based material and can display cockling, distortion, translucency, surface variation and sensitivity to environmental conditions. Its structure can therefore affect how it should be supported and imaged.
Stage 1 — Condition and structure
The document should be examined for folds, tears, holes, seals, attachments, surface media and distortion. Handling should be planned before imaging begins.
Stage 2 — Support without force
The aim is to support the parchment without pressing or flattening it aggressively. Any seals, cords or attachments must be accommodated within the imaging setup.
Stage 3 — Controlled imaging
High-quality capture should preserve writing, pigment, colour and other significant features. Lighting and positioning should be controlled to avoid unnecessary exposure and reflections.
Stage 4 — Quality assurance
The images should be checked for complete edges, legibility, focus, colour and any details obscured during capture. Where necessary, alternative views can document features that do not appear clearly in a single standard image.
Stage 5 — Preservation files
A project can create high-resolution master images alongside access derivatives. The physical parchment remains the primary object and should return to appropriate storage after digitisation.
A conservation-led approach
Where an item is too unstable for routine handling, conservators may need to stabilise it before imaging. Digitisation should not be allowed to become the cause of further damage.
Frequently Asked Questions
Can medieval parchment be digitised?
Many parchment documents can be digitised, but their condition and construction should be assessed before handling.
Can seals be included?
Yes, seals and attachments can be documented where the imaging setup can accommodate them safely.
Should parchment be flattened?
It should not be forcibly flattened simply to simplify scanning; appropriate support and imaging methods are preferable.
