In the past, carbon copy is a copy of a document that was created when a carbon paper was placed between the original and the bottom copy during the creation of the document. Currently "carbon copy" is often used metaphorically to refer only to exact copies. This is not to be confused with the carbon print family of the photographic reproduction process.

Use
A sheet of carbon paper is placed between two or more sheets of paper. Pressure applied by the stationery (pen, pencil, typewriter or punch printer) to the top sheet causes the pigment from the carbon paper to make the same mark on the copy sheet (s). More than one copy can be made by stacking several sheets of carbon paper between each pair. Four or five copies are practical limits. The top sheet is original and each additional sheet is called carbon copy .
The use of carbon copy decreases with the emergence of photocopying and the manufacture of electronic documents and distribution (word processing). Copies of carbon are sometimes still used in special applications: for example, in manual receipt books that have multi-use carbon sheet sheets provided, so that the user can keep an exact copy of every published receipt, even if here the carbonless copier paper is often used for the same effect.
It's still common for business letters to include, in the end, a list of names preceded by the abbreviation "CC", indicating that the named person should receive a copy of the letter, even though the carbon paper is no longer used to make a copy.
An alternative etymology is that "c:" is used to copy and "cc:" denotes plural, just like "p." means page and "pp." means page. This alternative etymology describes the frequent use of "c:" when only one recipient is registered, while "cc:" is used for two or more recipients. This etymology may also explain why, even initially, "cc:" is used for a list of recipients who receive a typed copy and do not have carbon copy.
The term "carbon copy" can be used in reference to anything that is a duplicate of the original ("... and you want to turn it into a carbon copy of every fourth level conformist in this dreaded land!", Heinlein, Foreigner in the Land Strange ).
Use as a verb
Copies of carbon may be used as transitive verbs with the meaning described below emails related to the CC field of email messages. That is, to send a message to an additional recipient outside the primary recipient. It is a common practice to abbreviate the verb form, and many forms are acceptable, including cc and cc: . Past tense forms used are CCed , cc'd , cc'ed , cc-ed and cc: 'd . The present participle or the imperfect form used include cc'ing . Merriam-Webster uses cc , cc'd and cc'ing , respectively.
Maps Carbon copy
In an email, the abbreviation CC shows those receiving copies of messages directed primarily to others (CC stands for carbon copy). The list of recipients in the copy is visible to all other message recipients. Additional fields BCC (blind carbon copy) available for hidden notifications; registered recipients in the BCC field receive a copy of the message, but are not shown on the copy of other recipients (including other BCC recipients). It is considered good practice to show other recipients that new participants have been added to the list of recipients (eg by writing "I send a copy to John Doe" or "John Doe, who is reading in copy, [...]").
In common usage, the To field recipient is the main viewer of the message, the recipient of the CC field is the other person the author wants to send the message publicly, and BCC the recipient of the field is the other person to whom the message was sent.
Printers
Dot matrix and daisy wheel printers can also use carbon paper to produce multiple copies of documents in one pass, and most models have adjustable impact strength and head distance to accommodate up to three copies plus original prints. Typically, this feature is used in conjunction with pre-arranged punched paper and prehash carbon stocks for use with tractor feeders, rather than on one sheet of paper, for example, when printing commercial invoices or receipts.
