Non-Exposure
Photocopy Transfer Method
Non-exposure negative plate making photocopy transfer method
plus image acquisition. ImagOn has great adhesive
qualities in addition to its photo sensitive qualities

Laminating the photocopy to the plate
- ImagOn layer is applied to a plate.
- Remove the top Mylar layer.
- take to the etching press for the
lamination of the photocopied image to the plate.
- ImagOn plate sprayed with the 50%
alcohol/water solution
- Position photocopy on top of the plate
with the photocopy toner facing in direct contact with the ImagOn
emulsion. Smooth out wrinkles in the photocopy with your hand or
a small hand squeegee.
- If photocopy does not completely cover
the ImagOn plate,
- For photocopies smaller than the plate,
save the top Mylar protection sheet for future use. This
prevents the ImagOn from sticking to the etching blankets. Plastic
kitchen wrap, clean sheet of polyester or bond paper could be also
used to protect the etching blankets.
- Position etching blankets.
- run through the press in the same manner in
which layers of ImagOn film are laminated to the plate.

Removing the
Laminated Photocopy
- After laminating the photocopy to the
ImagOn emulsion remove the top etching blanket protection layer and
then try to peel back as much of the photocopy paper that you
can. Because paper is made in layers quite a bit of paper that
can be removed before proceeding to the next step of submerging this
plate into a water bath. Remove this paper by pulling it away from the
plate with your fingertips. After removing as much paper with
your fingers place the plate in to a photo developing tray that is
half full of room temperature water. The remaining paper is vigorously
rubbed with your fingers to remove the rest of the paper. This can be
a lengthy procedure.
Developing the Plate
- Once all paper particles are removed
the plate is then submerged into the soda ash developing solution and
very carefully developed. Development in this instance is done without
friction by rocking the developing tray backwards and forwards until
all of the blue deposits of the ImagOn are removed. The aim is to
develop the plate without disturbing the photocopy toner that has
impregnated into the surface of the ImagOn.
- This developing procedure is extremely
sensitive to friction. The photocopy toner acts as a barrier in
preventing the soda ash developer from attacking the ImagOn emulsion
directly below the photocopy toner. After all traces of the
unprotected areas of ImagOn emulsion are removed the plate is then
dried and prepared for inking. At his point the plate could be etched
if a deeper relief area on the plate was needed.

Etching the Non-Exposure Photocopy Plate
- Etching the plate at this stage
accentuates the relief qualities of this method if a relief print is
what is wanted. The option exists to lay more than one layer of ImagOn
on to the plate to further accentuate the relief qualities of this
plate.
- Another option but less recommended
option to using the soda ash developing solution is to use the 1%
caustic soda or 4% soda ash solution. When using these solutions it is
not necessary to use any agitation as these liquids act more quickly
on removing the ImagOn emulsion.
- If there are open metal areas on the
plate and if an intaglio print is the intention then the plate can be
spray aquatinted with the Hunt Speedball Screen Filler method
previously mentioned and then etched. If a positive photo copy image
was used then this intaglio printing of the plate will yield a
negative image.
- If the plate is to be printed before
being etched some photocopy toners will cause the etching paper to
stick to the plate. To avoid this the plate should be light hardened
and then coated with a clear coat of Future acrylic floor finish.
After the floor finish has completely dried the plate can be inked in
relief or intaglio. An excellent relief ink for this purpose is the
Graphic Chemical water-soluble relief ink.

Using Transparent Photocopies
- Another method of transferring the
photocopy toner to the ImagOn emulsion is to make the photocopy on to
transparent film made for photocopies.
- Although this method can prove to be
frustrating, as it does not always release 100% of the photocopy toner
to the plate. It is however a technique that can be executed quickly.
- In this instance the transparent
photocopy is laminated to the ImagOn coated plate, as with the paper
photocopy, by running it through the etching press. Immediately after
lamination the edge of the transparent photocopy is lifted and quickly
pulled back on itself. The success of this technique relies on the
type of photocopy toner used, the pressure of the press, the
percentage of alcohol to water and the speed it which this procedure
is executed.
- If you stall halfway through this
removal procedure the point at which you stall will result in
photocopy toner not releasing to the plate. I have seen printmakers
creatively using this technique by reducing the pressure of the
etching press and then running the transparent photocopy through and
then abruptly stripping back this photocopy. This action resulted in
only about 50% of the photocopy transferring to the ImagOn plate. The
pressure of the press was then increased and the same photocopy
repositioned but slightly out of alignment and then run back through
the press. Again the transparent photocopy was pulled back resulting
in the rest of the image being transplanted to the plate. The effect
was similar to the photographic effect called bas-relief. The
plate was then treated, in one of the above ways, before it was
printed.

Rubber gloves RECOMMENDED for
the development procedure. Repeated use of developing solution can dry out
the skin and cause a dermatitis reaction on the hands.
Eye protection advised.
The developer is an alkaline solution. Do not
splash the developing solution into eyes.

Dry without heat

Reversal Techniques for the Non-Exposure
Photocopy Method
- Other techniques that can be used with
the Non Exposure Photocopy method involve exposing this plate to a
high UV light source. This is one technique that sunlight can provide
one of the most economical sources of light. After the photocopy toner
has been completely impregnated into the ImagOn film and all traces of
the photocopy paper are removed the plate can then be exposed to an UV
light source either through direct exposure to sunlight or through an
exposure unit.
- After exposure the photocopy toner must
be removed from the ImagOn plate to reveal the unexposed portions of
ImagOn emulsion. One way in which this can be done is to vigorously
scrub the surface of the plate with a mild nylon abrasive pot scourer
while it is in the soda ash developer. Once the photocopy toner is
removed then the ImagOn emulsion existing below the toner will develop
so that those areas of ImagOn emulsion should eventually be completely
removed from the plate.
|
Use dust mask and sand outside.
|
- Another alternative for removing this
photocopy toner is to sand the plate, after it has completely dried;
with an electric palm sander and 320 grit sandpaper. The aim is to
gradually sand the plate to remove most of the photocopy toner that
sits on the surface of the plate. As this technique does thin the
ImagOn emulsion two layers of ImagOn may be necessary at the outset if
the non-etch technique is to be employed.
The Non-Exposure Photocopy technique can be
useful in both the non-etch and etch methods. Once the Non-Exposure
Photocopy Method plate has fully developed, so that no residue of the
ImagOn emulsion exists on the developed portions of the plate, the
option exists to etch the plate in ferric chloride or to aquatint and
then etch the plate.

Clean Up of Printing Plate and Inking
Station
- Vegetable oil (canola) and a rag.
- Degrease with magnesium carbonate.
- Put up all paper, plates, inks on
personal or appropriate studio shelf and drawers.
Keep studio orderly
