Printing
Etchings on Claybord and Aquabord
Printing a zinc or
copper plate etching (or drypoint) onto the clay surface of Claybord or Aquabord has three distinct advantages over printing on paper.
• The permanence
of the print: Claybord is an archival surface
• The ability to
rework prints with mistakes or add finishing details and colors
• Glass free presentation
A matte acrylic varnish
or spray fixative like Krylon® UV Resistant Clear Coating #1309 (Matte) or #1305 (Gloss) sprayed on the Claybord works well and seems to bring out the relief caused
by the clay pressing into the etched lines of the plate. The following
exercise is a great place to start.
1. Etch a zinc or
copper plate as you would for printing on paper except for: a. Avoid deep
wide lines as the clay pressing into the line cannot "reach" the ink in
the bottom of the etched lines. b. Use as thin a metal plate as will take
your depth of etching and bevel the edges. The thicker plates seem to
be pushed by the press, digging into the clay surface.
2. Choose an appropriate
Claybord size and determine the placement of the image. Sand the edges
to prevent damage to the press blankets. If Aquabord is used, the surface should be lightly sanded.
3. Using matboard
or thick paper (should be same or slightly thinner than the metal plate),
cut a template with outside dimensions the same as the Claybord, with
an opening the size of the plate cut into it for consistent positioning
of the image during the edition. This also keeps the plate from moving
on the clay surface.
4. Ink and wipe the
plate as you would for a paper print.
5. Thoroughly wet
and sponge dry each piece of Claybord before printing, removing all excess
water with the sponge.
6. Place the damp
Claybord, clay side up, on the bed of the press. Position the template
on top and carefully drop the metal plate into the opening image side
down.
7. Print with moderately-heavy
pressure to force the softened clay into the etched lines to pick up the
ink. Allow to dry thoroughly.
8. Any ink smudges
around the image can be cleaned off with fine oil-free steel wool (0000).
The image itself can be redefined or manipulated with scratching tools.
9. Varnish with spray fixative like Krylon® UV Resistant Clear Coating #1309 (Matte) or #1305 (Gloss) and frame without glass and matting if desired.
Relief Printing
on Claybord and Aquabord
Relief printmaking
is one of the earliest methods used for printmaking. It is a direct and
a quick method for creating images. Whether you have a graphic style like
Picasso's linocuts, or finely detailed work like Albrecht Durer, Claybord
can be used successfully. Both Claybord and Aquabord can be used as relief plates. The thick clay coating allows the wood-cut
artist exceptional control and ease of cutting in all directions to achieve
uniquely detailed prints. To preserve the clarity of the cut edges, seal
withspray fixative like Krylon® UV Resistant Clear Coating #1309 (Matte) or #1305 (Gloss) or an acrylic varnish. There are many ways to prepare Claybord for relief
printmaking. The method below is a good exercise with which to start.
1. Cover the Claybord
with a thin even coat of a dark colored ink or watercolor. Use either
an airbrush, brayer(roller), or brush. Let dry. The paints or inks will
dry very quickly.
2. Cut the image you
want into the Claybord. Because cutting into the Claybord is so easy,
many tools can be used to create an image. They include woodcarving tools,
lino-tools, etching needles, scratchboard tools, craft knives, and engraving
tools. Where the white of the board shows through, it is not going to
print. Run a fingernail across the cut lines in the board. If the nail
catches in the lines, the cuts are deep enough. When printing relief,
the image will be in reverse. To see what the printed image will look
like hold it up to a mirror
3. When ready, prepare
the ink. If using oil-based inks, add about 15-20% plate oil to the ink
and mix well because Claybord will absorb the moisture from the ink. Roll
the ink with a brayer onto the palette/plexiglas until it looks like velvet
. Make sure the ink leaves an even coat on the brayer. Roll the ink on
the board until you have an even coat making sure the ink is not filling
the cut grooves. Have the paper ready to place on top of print.
4. Use a press to
print or hand rub the image onto the paper. When hand rubbing the image,
oriental paper should be used because it is more flexible and thinner.
Using a flat smooth piece of wood, rub over the back of the paper until
the image is transferred. Lift just a corner of the paper and look at
the image to determine if it is dark enough. If it is too light, roll
more ink onto the Claybord before printing.
Intaglio
Printing on Claybord and Aquabord
With intaglio prints,
the etched lines on the plate are printed using an etching press. Try
using Claybord as an intaglio plate because you can etch lines into the board without
having to use acid. The printing process then becomes less toxic when
using Claybord.
This exercise will help get you started.
1. Draw the image
you would like on the Claybord in pencil. Hold it up to a mirror to see
what the printed image will look like. Erase and correct until you get
the image desired.
2. Use the pencil
drawing as a guide and scratch over the lines using an etching needle,
burin or scratchboard tool.
3. After scratching
the lines, make a trial proof. When getting ready to print the image,
use ink that is thinner than usual or thin with an appropriate medium.
If using the normal ink thickness, it will be very difficult to wipe.
Apply the ink. Wipe off excess leaving the ink inside the cut grooves.
Then begin your printing process.
Tips on Printing
Serigraphs on Claybord
Claybord enables
exceptional registration and overall superior reproduction, making the
serigraph look like an original painting. A serigraph on Claybord can
be framed without glass, giving the viewer the same intimacy of an original
painting. They also command 40% more in the marketplace that those on
paper framed under glass! Warping, tearing, and shrinking are virtually
eliminated from the printing process, enabling improved reproduction performance.
Claybord's unique coating allows the artist the handwork each serigraph
if desired. Also, the luminosity of the panel provides a richness and
depth to the serigraph, similar to the oil and egg tempera masterpieces
of the Renaissance.
