to produce one or more copies of paper document
Carbon paper and "no carbon required" paper - otherwise known as "action paper".
Carbon paper was used inbetween sheets of paper to make duplicates either by typing on them or writing on them. The pressure of pressing on it deposited carbon on the sheets below creating the duplicates.
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.

Ordinary carbon paper is not to be used for tattoo transfer. Carbon paper will smear, distorting the image. In addition, carbon is not a good substance to put under the ski which will happen during the creation of the tatoo.
Carbon itself is not reactive with litmus paper as it is a non-metal element. Litmus paper is typically used to test for the presence of acids or bases. Carbon does not have acidic or basic properties, so it does not cause a visible change in litmus paper.
Carbon paper was widely used.
Actually, carbon paper is NOT used in sewing, because the carbon would stain fabrics. Special sewing copy paper can be used to transfer pattern marks onto fabric and these marks can be easily washed out of the finished garment. However, that is an outdated technique that is rarely used in modern home sewing.
No. Paper is cellulose, a carbohydrate usually derived from plant material. Carbon nanotubes are a variant of pure carbon that are used in a variety of high-strength materials.
Carbon paper is a second piece of paper, that is covered in a waxy substance and pigments. It is typically used to take a second copy of application forms and receipts.
The first inventor of carbon paper is thought to be Ralph Wedgwood, who patented his invention in 1806. Carbon paper was used for making multiple copies of handwritten documents before the advent of photocopiers and printers.
Triplicate. You don't hear it used to often anymore with the invention of the copy machine and electronic documents but they used to consist of a piece of paper usually white, carbon paper, yellow paper, carbon paper, pink paper. Or three white pieces with carbon paper in between them. Used for official documents. Something made in quadruplicate is an original and three copies. Triplicate is original and two copies.
