Vellum - Paper Vellum

Paper Vellum

Modern imitation or "paper vellum" is made from plasticized cotton. Usually translucent, paper vellum in various sizes is often used in applications where tracing is required, such as architectural plans. Like natural vellum, the synthetic is more dimensionally stable than a linen or paper sheet, which is frequently critical in the development of large scaled drawings and plans such as blueprints. It was also extremely important in that reproduction technology for dissemination of the plans as, like a high quality natural vellum, it could be produced in a thin enough sheet to be virtually transparent to strong light enabling a source drawing to be used directly in the reproduction of field-used drawings.
