Understanding Printmaking

On more than one occasion I have had to dash the hopes of an eager
novice art collector with the news that the recently acquired artwork
they had inherited or found at a yard sale was not an original artwork
at all, or even an original print. What in fact they had acquired was
a reproduction – sometimes a high quality, signed reproduction, but
more often than not just a reproduction.
Printmaking is still one of the most difficult art media to
understand, partly because of the variety of techniques used and
partly because of an ever-expanding technology which enables new
printmaking techniques to emerge and be accepted. Mostly though, there
is confusion about what constitutes an original print. This confusion
is further exacerbated by galleries and artists who either
deliberately or through their own ignorance sell mechanical offset
lithographs (reproductions) under the guise of signed original prints
or signed limited edition prints.
Galleries and artists sometimes see an opportunity to make fast
money by photographically reproducing a popular painting. It may be a
good quality reproduction on high quality paper, but it is still a
mechanical reproduction. The artist will in turn sign and number a
quantity of these reproductions and they are sold as limited edition
prints. Eager buyers see what they perceive to be an ideal opportunity
to own an original piece of art by a well known artist, at a very
reasonable price. They purchase these reproductions only to find that
their value as an original artwork is non-existent.
What is an Original Print?
It is sometimes easier to explain what an original print is not. It
is not a reproduction where an original painting is photographed and
then mechanically printed en masse resulting in what is essentially a
poster. An original print is also not a copy that has been quickly
churned out at the press of a button. The whole process involves
artistic input from creation to completion. A number of carefully
honed skills are needed to produce an original piece of fine art at a
fraction of the cost of an original painting or drawing.
So what IS an original print? First there must be distinction made
between ‘original print’ and ‘limited edition print’. The two terms
are not synonymous. An original print is a limited edition print but a
limited edition print is not necessarily an original print. Let me
explain.
A mass-produced, photo mechanical reproduction, or a poster is also
a limited edition print. These are generally produced in the thousands
but every process has a maximum number, hence ‘limited’. The artist
may decide to sign and number some of these. This is also often in the
thousands and should be the first indication that this is not an
original print.
The traditional techniques in fine art printmaking only allow small
editions. By working closely with the materials and processes of the
medium, the artist creates a number of prints, usually less than 100
depending on the technique used, before the plate, stone or screen
starts to deteriorate. After the edition is run there are no further
prints made of this precise image. If a set of prints are identical,
they are known as a limited print edition. Editions of twenty prints
are each numbered in pencil in the margin 1/20, 2/20…along with the
artist’s signature and title. Care and skill is required to print a
consistent edition as each print is printed by hand, taking a great
deal of time. More colours will require more work!
There are four main printmaking media – Etching, Lithography,
Screen-printing and Relief printing. As a painter may choose between
oil paint or watercolour, the artist-printmaker chooses the medium
which offers the desired effects and working method. To better
understand the original print it is helpful to understand the process
used in each of the main printmaking techniques.
Relief Printmaking
This is the oldest and most basic of printmaking techniques. It
includes wood cuts, wood engraving, linocuts and the most basic of all
processes, stamped prints. Woodcuts can be made on planks of wood as
well as plywood. The artist draws a design on the wood and carves away
the wood in the areas that are not to be printed. The raised surfaces
are then inked with a roller or brush and paper is placed over the
inked surface. Pressure is applied by hand or press to transfer the
ink from the wood surface to the paper. Often the wood grain becomes
an element of the final print. For more than a couple of colours,
separate blocks must be carved for each, then lined up, or
‘registered’, for a precise image.
Wood engravings are created in a similar manner to woodcuts. They,
however, are carved from the end grain of a piece of boxwood. Boxwood
does not grow very large and therefore the prints are generally small.
Because of the smooth uniform surface of the end grain, a wood
engraving does not show the texture of the wood and the carving can be
very detailed. In the past this method of printmaking was used
extensively for book illustrations.
Linocuts are yet another method of relief printmaking. They are
carved on battleship linoleum, which is more easily cut than wood and
eliminates any grain.
The most simple of relief printmaking are stamp prints. They
include potato block prints, finger prints and rubberstamp prints.
These are created by simply applying ink or paint to something and
transferring it to the paper or any surface to be printed.
Intaglio Printmaking
This method of printmaking is the opposite of relief printmaking.
Instead of a raised surface being printed, the recessed areas hold the
thick printer’s ink and the rest of the plate or printing surface is
wiped clean. Intaglio printmaking includes the traditional methods of
dry point, engraving, etching, aquatint, and mezzotint. The basic
principles are the same. A plate, usually copper or zinc, is marked,
scratched, gouged, etched or otherwise indented. A thick printer’s ink
is rubbed into the plate and the plate is then wiped clean. This
requires considerable skill. The marked, or incised areas, will retain
the ink. A printing press is necessary to apply sufficient pressure to
transfer the ink from the plate to the dampened paper. As with relief
printing, each added colour requires an additional plate which has to
be carefully registered to insure a clear image.
Dry point engraving and mezzotint are intaglio methods where the
images are scratched (dry point), gouged (engraving), or in the case
of mezzotint, rocked directly into the plate surface. With etching or
aquatint the plate is marked by acid biting into the surface of the
plate. Here the plate is protected with acid resistant wax and the wax
is scratched in the areas. The deeper the mark, the more ink it will
hold and the resulting printed area will be darker.
Original Lithograph Printmaking
This technique was invented in 1798 and is the basis for today’s
commercial printmaking process. As a fine art medium it still holds a
great appeal to many artists. In this medium the artist draws directly
onto a specially prepared surface of limestone, aluminum or zinc
(traditionally limestone). The artist uses the surface just as he/she
would a paper, using a greased or waxed crayon or a greasy drawing ink
called tusche.
After the drawing is complete the artist treats the surface with a
mixture of gum Arabic and dilute phosphoric acid. This reacts with the
surface which will accept the oil-based inks used to print.
Lithography is again a demanding process. The stone used during the
printing must be kept damp and then rolled up with oil based inks used
to print. The image can be lost if the water is too acidic or basic,
or if the stone is allowed to dry. When the image is inked, the paper
is placed over the stone or plate. The plate, paper and a greased
plate are run through a press. This press is different from an
intaglio press as rollers are replaced by a scraper bar made of
plastic or wood. As with the other print media, each individual colour
requires a new stone or plate and must be carefully aligned to create
a clear image.
Silkscreen Printmaking (serigraphy)
This is the only printmaking medium where the image is worked on as
it will be seen. (In the other printing techniques the printed image
is the mirror image of the plate, stone or wood from which it was
taken.) Screen printing is a form of stencil printing created in the
early 1900s and gained popularity by the 1920s. A finely woven fabric,
often nylon, orlon or silk is stretched over a wooden frame. The areas
that are not to be printed are blocked out of the screen or fabric by
varnish or glue. Sometimes photo emulsion films are used to replace
the hand painted process. After all the areas to remain untouched by
the ink are covered, a paper is put under the screen and ink is
squeezed through the fabric using a rubber squeegee. Large editions
can be made using this process, but again, each colour requires a new
screen and multiple printing.
