Carbon copy
From open-dictionary.com - the free dictionary.
Noun
- Copy produced in an alternated stack of ordinary sheets of paper and carbon papers. The pression applied on the top sheet (by a pen or typewriter) causes every carbon paper to release its carbon cover, thus reproducing the writing on the subjacent layers of paper.
