Etching technique:
In pure etching, a metal (usually copper, zinc or steel) plate is covered with a waxy ground which is resistant to acid. The artist then scratches off the ground with a pointed etching needle where he or she wants a line to appear in the finished piece, so exposing the bare metal. The échoppe, a tool with a slanted oval section, is also used for "swelling" lines. The plate is then dipped in a bath of acid, technically called the mordant (French for "biting") or etchant, or has acid washed over it. The acid "bites" into the metal (it dissolves part of the metal) where it is exposed, leaving behind lines sunk into the plate. The remaining ground is then cleaned off the plate. The plate is inked all over, and then the ink wiped off the surface, leaving only the ink in the etched lines.
The plate is then put through a high-pressure printing press together with a sheet of paper (often moistened to soften it). The paper picks up the ink from the etched lines, making a print. The process can be repeated many times; typically several hundred impressions (copies) could be printed before the plate shows much sign of wear. The work on the plate can also be added to by repeating the whole process; this creates an etching which exists in more than one state.
Etching has often been combined with other intaglio techniques such as engraving (e.g. Rembrandt) or aquatint (e.g. Goya). (Wikipedia information)

Printmaking technique:
Printmaking is the process of making artworks by printing, normally on paper. Printmaking normally covers only the process of creating prints that have an element of originality, rather than just being a photographic reproduction of a painting. Except in the case of monotyping, the process is capable of producing multiples of a same piece, which is called a print. Each print produced is not considered a "copy" but rather is considered an "original". This is because typically each print varies to an extent due to variables intrinsic to the printmaking process, and also because the imagery of a print is typically not simply a reproduction of another work but rather is often a unique image designed from the start to be expressed in a particular printmaking technique. A print may be known as an impression. Printmaking (other than monotyping) is not chosen only for its ability to produce multiple impressions, but rather for the unique qualities that each of the printmaking processes lends itself to.

Prints are created by transferring ink from a matrix or through a prepared screen to a sheet of paper or other material. Common types of matrices include: metal plates, usually copper or zinc, or polymer plates for engraving or etching; stone, aluminum, or polymer for lithography; blocks of wood for woodcuts and wood engravings; and linoleum for linocuts. Screens made of silk or synthetic fabrics are used for the screenprinting process. Other types of matrix substrates and related processes are discussed below.
Multiple impressions printed from the same matrix form an edition. Since the late 19th century, artists have generally signed individual impressions from an edition and often number the impressions to form a limited edition; the matrix is then destroyed so that no more prints can be produced. Prints may also be printed in book form, such as illustrated books or artist's books.

Archival Print
"Archival-Prints" are Museum-quality Fine-Art reproductions. Sometimes called "Giclee Prints", these artworks are made with an ultra-high-resolution fine-art printer, using the very finest archival inks and papers. Independant testing by Wilhelm Imaging Research Inc. (a world-leader in image-longevity testing) has established that these "Archival-Prints" will last more than 200 years before any noticable shift in color integrity occurs. They are truly "Museum-quality Fine-Art reproductions".
Archival-Prints are made with 2 different kinds of paper. The satin finish of the "Semi-Gloss" paper is the ideal surface for reproducing oil paintings. There is enough coating to provide the richest and most accurate colors, but not so much coating that reflective gloss makes the image difficult to see. Drawings and watercolor images are reproduced on "Archival-Matte" paper, an uncoated stock which gives the reproduction the look and feel of the original. The "251 gsm" weight of the paper (corresponding approximately to 100 Lb. cover paper) is also ideal. These art prints have not only the look, but also the heavyweight "feel" of fine-art prints: they are both sturdy and tear-resistant. (http://www.jonathonart.com/digital.html information)
