arkistolaatu

Arkistolaatu refers to the durability and longevity of materials used for archiving and preservation. It encompasses the physical and chemical properties of paper, ink, photographic media, and other storage formats that ensure their stability over extended periods, typically hundreds of years. Materials of arkistolaatu are designed to resist degradation caused by factors such as light, humidity, temperature fluctuations, and atmospheric pollutants.

Key characteristics of arkistolaatu materials include permanence, chemical stability, and resistance to physical damage. For paper, this means using acid-free, lignin-free pulp with a high rag content, and employing neutral or alkaline sizing agents. Inks should be fade-resistant and insoluble in water. Photographic materials must be processed to remove residual chemicals that can cause staining or deterioration over time.

The concept of arkistolaatu is crucial for cultural heritage institutions like libraries, archives, and museums. By selecting and using materials that meet these standards, these organizations can ensure that historical documents, photographs, and other records remain accessible and legible for future generations. Adherence to arkistolaatu principles is a fundamental aspect of modern archival and preservation practices, safeguarding our collective memory and historical record.
