Offset printing is a common printing technique in which the inked image is transferred from a plate to a rubber blanket and then to the printing surface. When used in combination with the lithographic process, which is based on the repulsion of oil and water, the offset technique employs a flat image carrier.

Are offset lithographs valuable?

Are Offset Lithographs Valuable? An offset lithograph print is usually much less valuable than original art created by a well-known artist or a hand-printed lithograph, but offset lithographs can still have the potential of being valuable.
