Etching:
Hard-Ground using FUTURE acrylic floor finish |
Materials:
- Future Acrylic Floor Wax
- Photo Processing tray
- Colorant for the Future Floor Wax
(Food coloring, batik dye, or water-soluble India ink
- Disposable Latex Gloves
- Plate drainage rack
- Copper plate
- Degreasing mechanism / material
for copper plate
- Etching needle
|
Since FUTURE
comes as a clear liquid you may want to add a small amount of blue food
color, Batik dye, or watersoluble India Ink so that it is easier to see
the hard-ground drawing on the copper plate. An alternative to adding a
dye to this hard-ground would be to ink the plate up with Graphic Chemical
water soluble relief ink after the FUTURE had dried on the
plate. |

If you are making a test plate,
proceed with this and the following steps for both plates:
Prepare Copper Plate
(for more complete info see Basic Plate
Preparation Handout)
- The metal (preferably roofing copper) plate is
thoroughly sanded with an electric finishing sander and 320 grit
wet-and-dry sandpaper and the sanding residue removed with a clean
rag.

Apply Acrylic Hard Ground
- Wear disposable latex or rubber gloves
- Pour Future Floor wax over degreased plate, hold
over photo tray
- Prop plate near vertically in the photo
tray. Support the plate with one hand against the plate while
pouring Future directly from the bottle with the other hand.
Pour from the top of the plate so that the Future cascades down the
plate surface. This action helps to break down the surface
tension and allow for a more even coating.
- The FUTURE is poured over the entire plate from
the upper most portion so that a veil of acrylic FUTURE covers the
entire plate.
- Avoid air bubbles on the plate. If air
bubbles occur "push" them off with another flow of the
acrylic.
- After the plate is coated, remove it from the
tray carrying it between the palms of your hands.
- Prop the plate up on newsprint to allow the
Future to run off the bosom of the plate onto the newsprint.
Reposition plate backward several times to allow more Future to run
off and not build up as a thick layer at the bottom.
- When the run off ceases, Set plate in vertical
plate rack
- Pour any Future residue from the photo tray back
into bottle and wash the tray in the sink with water. Excess dry
acrylic residue can be removes by first soaking it in a mild ammonia
solution (5:1 ammonia).
- Let plate dry. (Apx. 20 minutes - 1 hour)

Hard Ground Drawing
Techniques
- Make your drawing with the etching needle.
Remember to reverse the image, so that it will appear correctly when
printed.
- Any drawing implement that can cut thorough the
ground can be used as a drawing tool.
- The tool should glide freely through the ground
exposing the metal. If the instrument grabs or sticks you are
pressing too hard.
- Other drawing tools:
....mezzotint rockers
....roulettes
....burins
....star wheels used to mark fabric
....DremelTM
tools (grinding attachments)

Prepare plate for the
Etch
Protect Back of Plate
- Seal the back of the plate with packing tape,
contact paper, or a couple of coats of acrylic floor finish.
When the plate is dry, cover the back with contact paper or
overlapping strips of plastic, self-adhesive (Scotch brand) wrapping
tape to prevent the ferric chloride from biting the back of the
plate.
- When finished with the drawing stage and ready to
etch the plate, make a vertical tape hanger by sticking the tape
across the back, and creating a tail of apx 18" to suspend the
tape in the etching solution.
- Write name on tape, can take notes on
tape..

Etch in Ferric Chloride
- Lines will print light or dark depending on how
long the plate is in the ferric - not the pressure int he
drawing.Immerse the plate in the tank of ferric chloride to etch it.
You will probably want to make a small test plate the first few times
that you do this to see how different times affect the width and
darkness of the lines you make.
- To create areas with more delicate lines,
"stop out" lines before they have etched as deeply as lines
which you want to be darker and richer. The deeper and wider the
groove in the metal, the more ink it will hold and print, creating
darker areas. Many different line weights can be obtained in your
image by successive stopping out.
- The etching bath will bite into the surface of
the copper which has been exposed by your drawing.
- Ferric Rated at 42-49 Baume (45)
- The length of the bite to achieve desired results
is based on experience with the etch. I deep line etch can be achieved
in 30 minutes - 1 hour.
- To keep some lines lighter that others it
is necessary to "Block-out" areas.

Blockout technique(s)
Clean plate after removal from Ferric
- Remove plate from Ferric.
- Rinse with cool water
- De-oxidize with white vinegar and table salt
solution (3 T salt to 1 cup water). Rinse. Dry plate. (copper oxidizes
- in the ferric chloride and needs to be cleaned )
- Rinse with water
- Blot dry and then with hair dryer
- Use acrylic hard ground as a stop out by painting
out the lines that need to be blocked out. It is important to
use two coats for this making sure that the first coat is dry.
Two thin coats are better than one thick coat. Thick coats can
crack when they dry.

| . |
Progressive tonality
- Begin by drawing your dark lines.
- Etch.
- Remove from ferric. Rinse. De-oxidize with white
vinegar and table salt solution.
- Rinse with water
- Blot dry and then with hair dryer
- Add lines.
- REPEAT
Hard-ground washes
Disturb the hard ground surface while it is
wet.
- Impress with textures.
- Paint with brush charged with water to create
wash like tonalities.
Disturb the hard ground surface while it is dry.
- Tusche like washes
- Re-dissolve the ground and open up areas of the
plate using a mild ammonia and water solution and Q-Tips.. The
stronger the solution the quicker ground is removed.
|
| . |
Cleaning the ground
off the plate:
- If the plate is etched within the first day the
Future can be removed with a soda ash solution consisting of 1
teaspoon of soda ash in 1 litre of water (Same as the ImagOn
developer).
- As the acrylic goes through an extended
hardening/curing process over a 24 hour period the soda ash solution
will not work after the Future has been on the plate for more than 12
hours. After this time a 10% solution of ammonia and water, Mr. Clean,
or Comet cleanser is needed to remove the Future.
- There are non-ammonia smelling floor strippers
that are also available for removing FUTURE. But caution should be
exercised with these products.
Proofing the plate
- The plate can be proofed at any point without the
need to remove the Future. The final edition can be printed without
removing the Future. The Future provides a glass like surface to the
copper plate which makes it extremely easy to wipe not only
facilitates wiping but also is a great way to selectively add or
subtract plate tone.
- Cotton buds dipped into a mild ammonia solution
can be used to selective remove the FUTURE to allow plate tone to
infiltrate the printed image. This presents an image manipulation
opportunity that should not be ignored.and avoids unwanted plate tone.

Using the FUTURE as a
stop-out varnish:
- FUTURE can also be used to "stop out"
areas that you do not wish to etch while other, adjacent areas of the
plate remain in the Ferric Chloride solution.
- Use two thin coats of FUTURE rather than one
thick coat. A thick coat has a tendency to crack (which may be of
great interest to some printmakers). If you feel that the actual store
bought FUTURE is too liquid, leave it out for a few hours in an open
photo developing tray to allow the water particles to evaporate from
the acrylic. Monitor this evaporation until it reaches the desired
viscosity.
- After rinsing your plate with water, check the
depth of the etch with your fingernail, and look at it through your
magnifying glass. You can prook it without removing the FUTURE, and if
it is too pale, you can etch it further.

the Etched Plate

Etched Plate Handout |

Colored ink tips
- When working with colored ink, a solution of 50%
Future and 50% water can be used to coat the entire plate. This thin
coating does not block up even very fine marks yet serves as an
effective barrier for the inks from contamination by the metal
Print
Clean Up of Printing Plate and Inking Station
- Vegetable oil (canola) , degrease with magnesium
carbonate
