Carbon paper and "no carbon required" paper - otherwise known as "action paper".

A carbon copy is made by using carbon paper. Carbon paper is a very thin sheet of paper coated on one side with a film of carbon in suspension. The carbon paper is placed between two sheets of paper when intending to write or type (with a typewriter) on one of the sheets and to produce a duplicate of the writing on the second sheet of paper. It is important to have the carbon side of the carbon paper resting on the paper that will be the duplicate. The term "carbon copy" (abbreviated cc) is used to indicate the duplicate. Now, when it is possible to create duplicate copies by other means, the term "carbon copy" continues to be used to refer to the duplicate copies.
