Prints are a form of artwork that can be created in a variety of ways. Repros, or reproductions, are copies of an original artwork that are made to look as close to the original as possible. MARKS are impressions left on a surface by a tool or object. Prints can be made using a variety of techniques, such as woodblock printing, etching, lithography, and screen printing. Repros are usually made using digital technology, while MARKS are made using tools such as pens, pencils, and brushes.
