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]
The process was called mimeography, and a copy made by the process was a mimeograph. Mimeographs, along with spirit duplicators and hectographs, were common technologies for printing small quantities of a document, as in office work, classroom materials, and church bulletins.
A copying clerk would begin by counting the number of master letters to be written during the next few hours and by preparing the copying book. Suppose the clerk wanted to copy 20 one-page letters. In that case, he would insert a sheet of oiled paper into the copying book in front of the first tissue on which he wanted to make a copy of a letter.
A sheet of carbon paper, with the coating side down Handwriting duplicated through carbon paper. Carbon paper (originally carbonic paper) consists of sheets of paper that create one or more copies simultaneously with the creation of an original document when inscribed by a typewriter or ballpoint pen. The email term cc which means ‘carbon ...
Copying is the duplication of information or an artifact based on an instance of that information or artifact, and not using the process that originally generated it. With analog forms of information, copying is only possible to a limited degree of accuracy , which depends on the quality of the equipment used and the skill of the operator.
This has to do with the negatives (separations) being right- or wrong-reading and the image "flopping" during the transfer process. Because the carbon printing process uses pigments instead of dyes, it is capable of producing a far more archivally stable (permanent) print than any of the other color processes. Good examples of the color ...
Chester Floyd Carlson (February 8, 1906 – September 19, 1968) was an American physicist, inventor, and patent attorney born in Seattle, Washington.. Carlson invented electrophotography (now xerography, meaning "dry writing"), producing a dry copy in contrast to the wet copies then produced by the Photostat process; it is now used by millions of photocopiers worldwide.
