This chapter discusses some of the standard categories essential to the understanding and identification of printing and prints. The Three Types of Printing: Relief, Intaglio and Planographic All traditional printing belongs to one of three general types: relief, intaglio or planographic. The difference between these types is in a combination of the form of the printing plate and how the ink lays on or in the plate. These differences show up in the final print. A relief print is made by cutting away part of the surface of the printing plate, adding ink to the raised surface that is left and pressing the plate surface to the paper. The area that was cut away will not appear on the paper, while the area that was left will. If you take a block of wood, carve your initials into it, ink it up and press it on a piece of paper, you have made a relief print. Everything but your initials will appear on the paper. If you had instead cut away everything except your initials, it would print just your initials. Examples of relief printing includes woodcut, wood-engraving and linoleum cut. Intaglio printing also involves cutting away part of the surface of a printing plate. The difference from relief is that the ink is placed in the lower parts, or recesses, of the plate. During the printing process it takes great pressure to get the ink from the recesses onto the paper. Examples of intaglio printing include engraving, etching and dry point. Planographic printing involves a flat printing plate with the ink lying on the surface. As detailed later on, special substances placed on the plate surface isolate the ink into the desired image. The most common form of this printing is lithography. Miscellaneous. There are a number of processes that are not traditional. Some are barely prints at all. These include the monoprint and cliche-verre. These are, however, popularly included in the genre of prints. cycleback.com................conceits main (c) david rudd cycleback, cyclback.com all rights reserved
