Using letter copying presses, copies could be made up to twenty-four hours after a letter was written, though copies made within a few hours were best. 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.

A photocopier (also called copier or copy machine, and formerly Xerox machine, the generic trademark) is a machine that makes copies of documents and other visual images onto paper or plastic film quickly and cheaply.
A Polygraph is a duplicating device that produces a copy of a piece of writing simultaneously with the creation of the original, using pens and ink. Patented by John Isaac Hawkins on May 17, 1803, it was most famously used by the third U.S. president, Thomas Jefferson , who acquired his first polygraph in 1804 and later suggested improvements ...
1917 press room, using a line shaft power system. At right are several small platen jobbing presses, at left, a cylinder press.. With the advent of the Industrial Revolution and industrial mechanisation, inking was carried out by rollers that passed over the face of the type, then moved out of the way onto an ink plate to pick up a fresh film of ink for the next sheet.
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.
The so-called 'copy press' technology in this machine differed from the true xerographic reproduction in that it did not use a developer, utilized fewer electro-static charges in the printing engine (hence supposedly minimizing ozone emissions), and maintained a lower fusing temperature. Soon after, the company also developed an application for ...
In visual art, copying the works of the masters is a standard way that students learn to paint and sculpt. [1] Often, artists will use the term after to credit the original artist in the title of the copy (regardless of how similar the two works appear) such as in Vincent van Gogh's "First Steps (after Millet)" and Pablo Picasso's "Luncheon on the Grass, after Manet" (based on Manet's well ...
