Arkivblekk

Arkivblekk, also known as archival ink or permanent ink, refers to ink formulations designed for long-term document preservation. Unlike standard writing inks that can fade, degrade, or become soluble over time, archival inks are engineered to resist these detrimental effects. They are typically made with pigments rather than dyes, as pigments are insoluble particles that are more stable and less prone to fading when exposed to light or air.

The primary characteristic of archival ink is its permanence. This means it is intended to remain legible and stable for centuries, if not millennia, making it ideal for important historical documents, legal records, and artwork. Key properties include lightfastness, meaning it does not fade when exposed to UV light, and water resistance, ensuring that documents remain legible even if they come into contact with moisture. Archival inks are also resistant to chemical degradation and smudging once dry.

The development of archival ink has been crucial for the preservation of cultural heritage and the reliability of official records. While often more expensive than regular inks, their longevity justifies the cost for applications where enduring legibility is paramount. Many modern pens, particularly those used by artists and for official documentation, are now manufactured with archival-quality ink. The term "archival" can also be applied to other materials like paper and photographic prints, all with the shared goal of creating items that can withstand the passage of time.
