Vellum (derived from the Latin word vitulinum meaning made from calf, leading to Old French vÃ©lin, calfskin) often refers to a parchment made from calf skin, as opposed to that from other animals. It is prepared for writing or printing on, to produce single pages, scrolls, codices or books.
Vellum used to refer only to a type of paper made from calfskin, but modern vellum is made from cotton and wood pulp.. Print on vellum. A laserjet printer is best for printing on vellum, but you can use an inkjet printer if you're able to let the vellum sheet sit for several hours afterward while the ink dries. You can also use a printing pouch that adds a binding agent to the vellum or lightly sand the paper before printing.
