What Is An Aquatint?
An etching technique that produces an unlimited number of gradations of
tone from black to a very pale gray. It usually will have a granular
appearance. The name is not from the actual technique, but in its visual
similarity to that of a watercolor. The technique is usually used in
conjunction with other processes such as engraving or drypoint. The
majority of Goya's prints are done in a combination of aquatint and
etched lines.

Bon a Tirer:
This is a french term which translates as "good pull". It denotes that
the print that has just been pulled can be used as a guide to match up
the remainder of the prints that are pulled in the edition.

Collage:
The term Collage is from the French verb Coller meaning "to glue." In
English it means to attach objects to a surface. It can be used as
either a noun or a verb. The first collage in art was by Picasso, Still
Life with Chair Caning, produced in 1912. After World War I, the Dada
artists used found objects to make political statements. Since this
time, collage has been used by many artists to make statements about our
society. Since it uses real objects it has a particularly strong impact
in the form of social statement. Other artists involved in collage have
been Jasper Johns, Robert Rauschenberg, Richard Hamilton, and David
Hockney.

Collotype:
A photographic printing process in which a glass plate whose surface has
been coated with gelatin carries the image to be reproduced.

Etching:
Etching (derived from the Latin radere, to scratch, to scrape) is a
printing method in which the ink-receptive indentations are not produced
mechanically but chemically (etchings). In this method a polished metal
plate (copper or zinc) is covered by an acid-resistant layer (wax,
mastic or asphalt) and is blackened with a fumigating candle, in order
to render the design, which is to be applied, more visible.
Then, the artist draws or scores the etch resisting layer with an
etching needle, without penetrating the material. In the etching bath
the acid then soaks into the lines created by the artist. Short or long
etching times can influence etching depth. In many cases the work is
additionally treated by dry point technique afterwards. Then, the plate
is cleaned, steel-plated for the printing process and inked. The ink
then gets into the etching indentations.
Afterwards the plate is cleaned so that the ink remains only inside the
indentations. Then the artist presses a wettened print sheet onto the
plate. Depending on the colordesired, this process is repeated several
times. For the Carborundum-Etching (a method developed by Antoni Tapies)
the metal plate is covered, in the same way as is described above, by a
mixture of polyester, gypsum, and other materials chosen by the artists,
creating a thickly coated surface (the way it is done in a collage).
Additional printing inks can be applied, too. Then, in another printing
process, the wettened paper is pressed onto these reliefs. In this way
the sheets are given relief-like structures, an additional artistic
feature.

Giclee (Pronounced - Gee-Clay):
The word giclee is French for "to spray" and was given to the method of
plate-less fine art printing developed in 1989. It is also the
registered trade name for the Iris Printer. Images are scanned and
stored digitally by computer then sent to a high resolution printer. The
ink is then sprayed onto paper or canvas mounted onto a drum which
rotates as the inks are applied. Very high resolution reproductions can
be obtained using this method of printing.

Gouache:
Opaque watercolor paint. Most commonly used for commercial illustration.
Can be mixed with transparent watercolors to make less opaque. These
paints are made by adding chalk to the pigments to make them opaque. The
use of gouache goes back to medieval manuscript illumination and was
used in 16th - 18th century minature painting. Many painters combine
gouache, pastel watercolors and India ink in the same painting.

Intaglio:
Any print or printing process that uses the idea of the ink being in
recessed grooves in the plate. The plates are inked and then wiped. The
print is made by pressing a damp print paper in the plate and the ink is
drawn up out of the grooves and onto the paper. Some of the processes
included in this category are etching, engraving, drypoint, and
photogravure.

Limited Edition:
An edition is a set of identical prints numbered and signed by the
artist. Two numbers are often written at the lower edge of a print; the
first indicates the print place in the order of all prints in the
edition; the second number indicates the total number of prints for that
type of numbering in the edition.
There can be several different types of numbering systems used to number
an edition. Examples are: Arabic, Artists Proof, Roman Numerals, HC
(Hors d'Commerce), M (Museum Edition), PP (Printers Proofs), EP
(Exhibition Proofs), TP (Trial Proofs) and others.
To get the "total" edition size of your print you must add up all the
ways the edition has been numbered, for example:
Print "X" has been numbered the following way:
200 Arabic - 1/200 through 200/200
25 Artist Proofs - AP 1/25 through AP 25/25
30 HC (Hors d'Commerce) - HC 1/30 through HC 30/30
5 M (Museum Edition) - M 1/5 through M 5/5
3 PP (Printers Proofs) - PP 1/3 through PP 3/3
Total Edition Size for print "X" is 263
Example of Limited Edition Numbers:
ARABIC NUMBERS - Arabic numbers refer to our own system of numbers 0 -
9. An arabic numbered piece would be a fraction such as 1/150 - the top
number denoting the sequence in the edition, the bottom number denoting
the total number of prints in the arabic edition.
ROMAN NUMERALS - Roman numbers would also be shown as a fraction when
numbered on the artwork such as: II/C the top number denoting the
sequence in the edition, the bottom number denoting the total number of
prints in the roman numeral edition.
ARTIST PROOF - ADDITIONAL PROOFS FROM A PRINT RUN THAT CAN EITHER BE
INCLUDED IN THE REGULAR EDITION OR PULLED FOR THE ARTISTS APPROVAL AND
RETAINED FOR HIS PERSONAL USE. Artists proofs can be marked AP either
with or without a number that denotes how many were run. Example AP or
AP 1/50 OR AP I/L.
HORS D' COMMERCE This French term means "before business". Originally
Hors Commerce prints were used as the color key and printing guide for
the printer to insure consistency of the run. In modern serigraphy that
are usually used to extend the numbering of the run. The letters HC can
be used either with or without a number that denotes how many were run.
EXAMPLE HC OR HC 1/100 OR HC I/C.
TRIAL PROOF - A Trial Proof originally was used in a similar fashion as
the Hors Commerce - as a guide to the printer before printing the
edition. Trial proofs can also be different colored prints than those
used in the regular edition. Andy Warhol frequently added Trial proofs
in addition to his regular pieces where varied colors were used in the
body of the image and the background. The letters TP can be used either
with or without a number that denotes how many were run. Example TP or
TP 1/50 OR TP I/L. Pieces numbered TRIAL PROOF can be used as an
extension of the regular run or they can be entirely different colors
from the regular run.

What Is Lithography?
Lithography is a planographic method of printing, which was invented in
1798. The name derives from the Greek words for litho (= stone) and
graphein (= to write). The litho stone, a fine pored limestone, is water
and grease friendly. With the aid of grindstones of different grains the
wet stone is cut completely plane. Afterwards the design is put or
sprayed on with lithocrayon and lithographic drawing ink. Then, the
stone is etched. The aim of etching is to make those parts of the stone,
which are covered by design, able to absorb grease, whereas those parts
which are not covered by design are prepared to absorb water and to
repel grease. In order to protect the design it is then covered with
talcum. Afterwards, a mixture of dissolved gum Arabic and nitric acid is
applied, which has to dry up. In this way the pores in the stone close
at those parts which are not covered by the design, whereas at those
parts which are covered by design, the acid saponifies with the
lithocrayon. Thus, crayon and ink become insoluble in water.
Then the etching is washed off and the design is again supplied with
grease by applying a washing-out solution, consisting of asphalt,
dissoved in oil of turpentine, virgin wax, wood tar and lavender wax.
Now the design is perfectly visable on the stone.
Onto the stone, which is always kept wet, the desired printing ink is
now applied with a rough leather or rubber roller. Printing is carried
out with the stone press. The strong pressure exerted by the scraper
transmits the printing ink from the stone onto the paper. For every new
ink a new stone is prepared. The number of inks to be used is unlimited,
still, it is also a question of cost.

Monoprint:
One of a series of prints in which each has some differences of color,
design, texture, etc applied to an underlying common image.
-back to top-
Monotype:
One of a kind print made by painting on a smooth metal, glass or stone
plate and then printing on paper - the pressure of printing creates a
texture not possible when painting directly on paper (not to be confused
with a mono-print).
-back to top-
Plate Signed:
Prints in which the artist's signature is put onto the plate itself and
then transferred to the print through the same process as the rest of
the design.

Remarque:
A sketch made by the artist on the margin of the print - sometimes in
black or colored pencil or watercolor.

Silk-Screen "Serigraph" Printing:
Silk-screen "serigraph" printing has been used only since the early 20th
century. It's name derives from the Serian people to whom Europe owes
the discovery of silk. In the beginning, raw silk gauze was used for the
screens, today a fine-meshed polyester fabric has replaced silk. In
silk-screen "serigraph" printing a metal frame, which has a polyester
screen stretched across one side, serves as printing form. The artist
inks this screen (with pencils, a brush or a sprayer) with gum Arabic,
glue or cellulose varnish. For the printing process the artist covers
all those parts on to which the ink is supposed not to penetrate. We
can, thus, compare the screen to a stencil, which is partially covered.
For the printing process the paper is put underneath the screen, leaving
a gap of about 3 millimeters between the paper and the screen. The
screen is covered with a little ink, which is spread by means of a
squeegee, a handle with a rubberedge. The pressure exerted by the
squeegee forces the ink to flow through the open parts in the screen and
is then homogeneously spread on the paper underneath. As is the case in
all printing methods, in silk-screen printing, too, the artist needs a
new printing form, i.e. a new screen, for every new ink he applies.

Woodcut:
A relief printing technique in which the printing surface is carved with
special tools in a solid block of wood. The wood is cut longitudinally
from the tree so the grain runs the length of the block. The block is
cut and then inked with a brayer or dabber. The paper is then placed in
the block and the whole thing is run through a press or rubbed over by a
baren or the bowl of a large spoon. This art form was developed in
Europe in the 14th century. The oldest prints from wood blocks are
playing cards. It reached its height in skill with the work of skilled
artisans carrying out the designs of such great artists as Albrecht
Dürer. The use of etchings and line engravings pushed woodcuts out of
the center of attention for fine art in the 17th century. It was revived
as an artistic medium in the 19th century by such artists as Gauguin and
Millet. Edvard Munch designed, cut, and printed his own woodcuts adding
to the revival.
