20 lb. Xerographic Engineering Vellum
Modern technology has created our awesome engineering laser/LED vellum. Our 100% cotton fiber base is transparentized with environmentally friendly solvents, and surface treatment is applied to produce an extremely smooth faced sheet with excellent pickup and minimal solvent migration. Lines and graphics come out clear, sharp, and dense. 100% cotton means that our vellum will stand up to long term archiving needs.
