COLLAGRAPH

Part of the intaglio family. A constructive process in which objects (cardboard, fibers, fabrics, organic materials etc) and sand or carborandum are added to the surface of the plate, usually heavy cardboard, until a low relief is achieved. Front, back and sides of the plate are then sealed with several coats of acrylic mat medium. Once the plate is dry it can be inked, wiped and printed in the same manner as a etched metal plate. Collagraphs can also be printed as relief images, without any ink as a blind embossing. Because the various levels on the plate are so easily achieved, it lends itself beautifully to multicolored and viscosity printing.

ETCHING

In this technique the plate is covered with an acid resistant ground, then worked with an etching needle to create an image. The thus exposed metal is then "eaten" in an acid bath or etchant, creating depressed lines that are inked and printed. The etched line does not have the smooth, crisp quality of the engraved line. It is usually sharply defined, but slightly irregular due to the action of the etchant biting into the metal plate. Etching was developed during the 16th century, and started to replace engraving by the 17th century.

MONOTYPE

Monotypes, described simply, are printed paintings or drawings. These unique works of art, executed in ink or oil paint, prior to transferring to paper via a printing press, record clearly the artist's painterly and adventurous manipulations of pigment on a surface of metal or Plexiglas while creating an image.

In terms of technique, the monotype is the simplest form of printmaking, requiring only pigments, a surface on winch to apply them, paper and some form of press. Traditional forms of printmaking like woodcut, etching, engraving or lithography involve much more complex processes of physically or chemically cutting or fixing an image in wood, metal or stone so that it may be inked and printed repeatedly.

Monotypes, as we are familiar with them, became relatively common late in the nineteenth century but the technical knowledge to create them has existed about as long as the intaglio process which dates from the fifteenth century. Although the means to create the monotype existed, the potential of its practice awaited the artists and artistic conditions necessary for it to emerge. The first known reference to the monotype was early in the nineteenth century.

Although certainly not the first artist to use the monotype, the greatest innovator and practitioner of the medium in the nineteenth century was Edgar Degas. Degas did more than any other artist to make the monotype an important and viable medium for artistic expression. In only a little over fifteen years of exploration of the medium, Degas created over four hundred and fifty monotypes. His perception and sense of experimentation gave to artists and the world insights into color, light and spontaneity unique to the monotype.

Other qualities which make the monotype unique as a medium are its freed flexibility and organic spontaneity of application. These characteristics, blended with the special transparent nature of oil based inks or paint, that may be brushed, rolled, blotted, wiped and smeared into an artistic semblance, comes alive when transferred on to paper. Once the image is printed the potential for further enhancement exists through the addition of more detail and hand-coloring. The extent to which a printed image is altered, since it is a unique, is entirely up to artistic preference.

Monotypes, because of their innate uniqueness as a printed painting of which there is only one, are an important addition to any fine art collection.

PHOTOGRAVURE

This process has become revived recently with the introduction of safer, light-sensitive polymer films and plates adapted from the circuit board industry. The image is generated by exposing a photo positive to a photo polymer plate via a high powered light. Usually, artists need to do extensive testing to determine the exact exposing time for each image. The exposed plate is developed in water and can be printed almost immediately. It is important to understand that photo etchings are not a means of reproducing existing photographs or drawings. Photographs that will become the base for the photo etching usually need to be shot and developed differently than for photographic prints. Equally, for drawing-based photo etchings artists need to create a new drawing on mylar which will become the photo positive. For this drawing, artists need to keep in mind the specifics of the photo etching process (gain of contrast, loss of light grays, etc) just as lithographers who create drawings on plates or stones need to keep in mind the specifics of the lithography process.

The advantage of photo etching is it’s flexibility, which allows artists from varied backgrounds such as photography, computer graphics, and drawing to create hand printed limited editions.

RELIEF

A technique in which the image is printed from a raised surface, usually produced by cutting away
non-image areas.
