The resulting finished print, whether composed of several layers and in full color or having only a single monochrome layer, exhibits a very slight bas-relief effect and a variation of texture on its surface, both distinctive characteristics of a carbon print. The process is time-consuming and labor-intensive.
Agfacolor. Ap-41 process (pre-1978 Agfa color slides; 1978-1983 was a transition period when Agfa slowly changed their color slide films from AP-41 to E6); Anthotype; Autochrome Lumière, 1903
Essentially, a Woodburytype is a mold produced copy of an original photographic negative with a tonal range similar to a carbon print. The process was introduced by the English photographer Walter B. Woodbury and was in use during the final third of the 19th century, most commonly for illustrating fine books with photographic portraits.
Although the name "hecto-graph" implies production of 100 copies, in reality the gelatin process produced print runs of somewhere between 20 and 80 copies, depending upon the skill of the user and the quality of the original. At least eight different colors of hectographic ink were available at one time, but purple was the most popular because ...
Carbon tissue is a gelatin-based emulsion used as a photoresist in the chemical etching (photoengraving) of gravure cylinders [1] for printing. This was introduced by British physicist and chemist Joseph Swan [2] [3] in 1864. [4] It has been used in photographic reproduction since the early days of photography. [5]
To print a carborundum print, the surface is covered in ink, and then the surface is wiped clean with tarlatan cloth or newspaper, leaving ink only in the texture of the screen or carborundum. A damp piece of paper is placed on top, and the plate and paper are run through a printing press that, through pressure, transfers the ink from the ...

The printing cylinders are usually made from copper plated steel, which is subsequently chromed, and may be produced by diamond engraving; etching, or laser ablation. Gravure printing is known for its ability to produce high-quality, high-resolution images with accurate color reproduction and using viscosity control equipment during production.
