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:
“It requires a surgical operation to get a joke well into a Scotch understanding. The only idea of wit, or rather that inferior variety of the electric talent which prevails occasionally in the North, and which, under the name of “Wut,” is so infinitely distressing to people of good taste, is laughing immoderately at stated intervals.”
—Sydney Smith (1771–1845)
“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)
“You may read any quantity of books, and you may almost as ignorant as you were at starting, if you don’t have, at the back of your minds, the change for words in definite images which can only be acquired through the operation of your observing faculties on the phenomena of nature.”
—Thomas Henry Huxley (1825–95)
