Relief Printing Methods
Woodcut techniques were
used as early as the 5th century in
Around the middle of the sixteenth century
the woodcut began to fall out of favour as artists explored, then preferred,
other more exacting graphic techniques. Thanks largely to early
twentieth century expressionists— who found the technique perfectly suited to
their needs—the woodcut once again prevailed.
To create a woodcut print, the artist
sketches an image on a soft wood plank, then chisels away—along the grain of
the wood— those parts of the design which are not to be printed. The
resulting surface of the design, or relief, is then inked, covered with a sheet
of paper, and pressed, creating the woodcut print.
Wood Engraving, a variation of
the woodcut was invented in the late eighteenth century, the difference being
that the design is created on the end grain of the wood rather than the flat
face. Using a harder wood, such as boxwood, a graver or burin
is used to create much finer lines than is possible with woodcut. Due to the thin, strong blocks the wood engraving can be
printed with high pressure and was once used worldwide as a method of
illustrating books and periodicals. By the
early twentieth century, as with woodcut, wood engraving re-emerged as a
favoured medium of artistic expression.
Linocut, invented in the
twentieth century, is created in the same manner as a woodcut. Being
soft and without grain, it is easier to cut in any direction, thus greater
detail may be achieved. Many modern
masters—notably Picasso—favoured this medium.
Intaglio Printing Methods
The first etching on record was done by
To create an etching, a metal (often
copper) plate is covered with an acid-resistant substance (etching ground or
varnish—hard ground) and then a design is drawn with a needle or other
sharp tool. The plate is then bathed in acid, which attacks only the
exposed lines. The longer the plate is
exposed to the acid, the coarser the lines. After
removing the ground, the plate is inked and its surface wiped clean, then
covered with damp paper and passed under a cylindrical press. The ink captured in the etched lines is then transferred
to the paper, resulting in an etching.
When creating a soft
ground etching, a special acid resistant substance is applied to the plate
into which different materials or objects can be pressed. The
amount of pressure applied results in how much soft ground is lifted from the
plate. The more that is removed the more
exposed the plate will be to the acid bath and vice versa. This technique allows unlimited possibilities for the
creation of tonal range and texture.
To create an aquatint, the artist uses a
porous ground or series of ground such as sand or resin, instead of covering
the plate with hard ground. This allows for the creation of granular
and tonal effects on the plate when exposed to the acid, and is often used in
combination with etching for its richness of tone. Goya is considered the greatest master of this technique.
Drypoint is another method
often used in conjunction with etching. In this method, lines are
scratched or gouged onto the plate with a sharp tool, leaving a burr in the
metal. When printed, the burr leaves
distinctive velvety lines. Due to the
gradual breaking down of the burr, relatively few impressions can be
successfully printed using this method.
Planographic Printing
Accidentally discovered in 1798 by
Based on the principal that oil and water are
repellents, the method requires the drawing of a design onto a heavy limestone
slab or litho plate with a grease pencil. The surface is moistened
with water and then rolled over with an oil based ink. This ink is attracted to the grease-penciled design,
whereas where the surface is damp and clean, the ink is repelled. The stone is then covered with a sheet of paper and run
through a lithographic press, resulting in the image being transferred to the
paper.
Chromolithography simply means
lithography in colours.
To achieve this, a series of carefully registered
stones are used with an individual printing for each colour, sometimes
numbering more than thirty. Toulouse-Lautrec,
Edvard Munch and Gaugin are a few artists noted for their exceptional skill
with this method.
The technique used in lithography permits
an artist to produce an astounding number of prints, though the stone is
traditionally re-polished in order to limit the edition size. Lithography
should not be confused with offset lithography, a publishing method based on
photographic processes.
Serigraph
or
Silkscreen
Not considered a fine art form until the
1930s, the stencil based technique of silkscreen actually originated
in
Silkscreen involves stretching porous fabric
(such as silk) tightly over a frame and painting areas of the fabric with a
substance such as glue, creating a type of stencil. Ink
is then pressed with a squeegee through the unglued, remaining portions of
fabric onto paper beneath the screen. Several
screens can be used to achieve multi-coloured prints.
Collograph
The term collograph is derived from
the Greek word collo, meaning glue,
and graph meaning the occupation of
drawing. Collography is a printmaking process in which materials
are glued to a rigid surface such as cardboard or wood. The materials used are as varied as the imagination
allows.
Different tonal effects and vibrant colours
can be achieved through the depth of relief and the highly textured surface. When
the glued collage has dried it is ready to be inked using the artist’s choice
of method. Printing is accomplished with a
press or by hand burnishing.
Monotype
Monotype is a one-off
printmaking method in which a flat surface, such as glass, copper, or zinc is
painted with oil colours or ink and then passed through an etching press. The
technique allows for only one copy, or monotype. A wide variety of materials from cardboard to perspex are used in the
creation of modern monotypes allowing artists to create veritable collages on
the surface, then printing with interesting and often surprising results.
