Definitions Kozo Paper Kozo papers are made from the fibers of mulberry trees. The fibers are long and extremely strong, and can be used to make especially lightweight papers.   Lithography A planographic printing process developed by Alois Senefelder in 1798. Flat limestones, or aluminum plates are marked using a greasy crayon or paint (lithographic tusche). The stone or plate is then etched using (usually) tannic acid. When the printing surface is wiped with a damp sponge, water is repelled on the drawn image, but pools on the etched areas. This allows oil based ink, applied by a rubber roller, to adhere to the drawing, but not to the area holding water. When fully inked, the stone or plate is covered with a sheet of paper, and sent through a lithographic press, where the impression is transferred to the paper under pressure.   Mezzotint An Intaglio process employing a tool called a ‘rocker’ that has spikes on its surface designed to make linear indentations on the surface of a metal plate. The pattern produces an overall velvety black texture when printed. In this process the artist works from black to white scraping and burnishing areas smooth in order to produce shapes or patterns from gray to white.   Mixed Media A term used to describe works of art that incorporats multiple techniques. For example, a mixed media print may have layers of screen printing, lithography, and a collage element. Mixed media works may be an edition, or one-of-a-kind.   Mold-made Paper Paper that was made in a cylindrical mold machine. The machine forms a continuous sheet, sometimes 100 yards long. Fine mold-made papers such as Arches or BFK are available in sheets or rolls.
