What is the significance of archival paper in art?

Archival paper is significant in the realm of art primarily because it prevents deterioration and discoloration over time. This type of paper is crafted using specific materials and processes that ensure longevity, making it ideal for artists who want to preserve their work for future generations. This preservation quality is due to the use of acid-free materials which resist yellowing and degradation, maintaining the integrity of the artwork without damage from environmental factors.

In contrast, while some forms of archival paper may be used for sketching or watercolor painting, these are not the defining features of archival paper itself. Sketching papers or watercolor papers may prioritize texture and absorbency over long-term preservation. Additionally, the use of archival paper extends beyond just illustration boards—it serves a wide range of artistic applications, but its key characteristic remains its archival quality that safeguards the artwork's condition.
