Operation
Carbon paper is placed between the original and a second sheet to be copied onto. As the user writes or types on the original, the pressure from the pen or typeface deposits the ink on the blank sheet, thus creating a "carbon copy" of the original document. This technique is generally limited to four or five copies.
As the ink is transferred from the carbon paper to the underlying paper, an impression of the corresponding text is left on the "carbon" where the ink was removed. A single piece of carbon paper can be repeatedly reused until the impression grows too light.

Famous quotes containing the word operation:
“An absolute can only be given in an intuition, while all the rest has to do with analysis. We call intuition here the sympathy by which one is transported into the interior of an object in order to coincide with what there is unique and consequently inexpressible in it. Analysis, on the contrary, is the operation which reduces the object to elements already known.”
—Henri Bergson (1859–1941)
“Human knowledge and human power meet in one; for where the cause is not known the effect cannot be produced. Nature to be commanded must be obeyed; and that which in contemplation is as the cause is in operation as the rule.”
—Francis Bacon (1560–1626)
