Kertanäytteen
Kertanäytteen, often translated as "sample of paper" or "paper sample," refers to a physical specimen of paper used for various analytical and testing purposes. These samples are crucial for understanding the properties, composition, and historical context of a particular paper material. In archival and conservation settings, kertanäytteen are taken to document the condition of a document, to test for acidity, lignin content, ink bleed-through, or to analyze fiber composition. The process of taking a kertanäytteen is usually done with minimal invasiveness, often from inconspicuous areas of a document to preserve its integrity.
Beyond preservation, kertanäytteen are also used in research and development within the paper industry. Manufacturers might
