A copy made with carbon paper. Before the development of photographic copiers, a carbon copy was the under-copy of a typed or written document placed over carbon paper and the under-copy sheet itself (not to be confused with the carbon print family of photographic reproduction processes). [1]

A substance known as "carbon paper" is also used in fuel cell applications. However, this carbon paper has nothing to do with the carbon paper used for copying texts. It consists of carbon microfibers manufactured into flat sheets. It is used to help as an electrode that facilitates diffusion of reagents across the catalyst layered membrane ...
The carbon process, initially a black-and-white process using lampblack (carbon black), was invented by Alphonse Poitevin in 1855. The process was later adapted to color, through the use of pigments, by Louis Ducos du Hauron in 1868. Carbon printing remained commercially popular through the first half of the 20th century.
Carbonless copy paper was first produced by the NCR Corporation, applying for a patent on June 30, 1953. [2] Formerly, the options were to write documents more than once or use carbon paper, which was inserted between the sheet being written upon and the copy. Carbonless paper was used as business stationery requiring one or more copies of the ...
[2] [3] It was a form of thermographic printing and an example of a dry silver process. [4] It was a significant advance as no chemicals were required, other than those contained in the copy paper itself. A thin sheet of heat sensitive copy paper was placed on the original document to be copied, and exposed to infrared energy. Wherever the ...
The special aniline dyes for making the master image came in the form of ink or in pens, pencils, carbon paper and even typewriter ribbon. Hectograph pencils and pens are sometimes still available. Various other inks have been found usable to varying degrees in the process; master sheets for spirit duplicators have also been pressed into ...
Water transfer printing, also known as immersion printing, water transfer imaging, hydro dipping, watermarbling, cubic printing, Hydrographics, or HydroGraphics, is a method of applying printed designs to three-dimensional surfaces. The resulting combinations may be considered decorative art or applied art. The hydrographic process can be used ...
