Is acid-free or archival paper necessary for fountain pen and calligraphy work?

Yes, using acid‑free (or archival) paper is highly recommended—especially for cherished documents or artwork—because:

Longevity: Acid‑free paper is manufactured to have a neutral or slightly alkaline pH which slows down the deterioration process. This helps prevent yellowing or brittleness over time, keeping your work looking fresh and true‑to‑color for decades .

Preservation of Ink Quality: Archival paper is designed to maintain its structure and appearance, ensuring that inks remain vibrant and do not react adversely with the paper over long periods. This is important whether you’re producing a daily journal entry, a calligraphy piece, or preserving archival documents.

Professional Appeal: For art prints and high‑quality stationery, the stability offered by acid‑free paper contributes significantly to the overall aesthetic and durability—an essential factor if you intend to archive your work or present it professionally.

Thus, while you might use standard paper for drafts or everyday notes, investing in archival‑quality paper can make a big difference in the longevity and appearance of your finished work.
