2. Lamination
Standard
Lamination
- Cut filrn slightly
larger then plate size
- Place degreased plate
(with alcohol) on clean glass slab, or any other hard
surface that does not absorb water.
- Spritz plate with
water
The film
consists of three layers: a transparant plastic
layer ("mylar") on both sides of the film, and
the actual photosensitive emulsion as a layer in
between. The film comes on a roll, the inner
layer is the one at the inside of the
"curl"
|
Remove
inside peel-back layer (inside of film curl)
from the ImagOn Ultra. This can be done by
prying off the inner layer, but the easiest way
is probably as shown in the image; a piece of
double-sides tape on a table corner. A corner of
the film sticks to the tape and with some
training the inner layer be relaesed from the
film.
|
- Place film (mylar on
top) flat on plate by gently laying it down from one end
of the plate. If bubbles appear under film lift one comer
of the film and lay it back down.
- Spritz top of film
generously with water
Gently and
quickly squeegee the film from the center
outwards, until the film is smooth. Repeat with
increasing pressure until all water and air
bubbles are no longer visible
|

|
- Sponge dry the surface
from the center out, rub harder where Imagon is not
sticking thoroughly, pay special attention to the
edges.
While still on
the glass slab trim the excess film from the
edges of the plate
|

|
Bond the film to
the plate using a drying cabinet (5 minutes at
appr. 50° C) or a hair dryer on the
backside of the plate, set on high for about one
minute per sq.ft area. (1 square foot =
30x30cm)
|

|
- The laminated plate is
now ready for image exposure with the UV exposure
unit
Plates targer than 9 +
12
- Do steps 1-4 of Standard
Lamination
- Spritz the plate and the
emulsion side of the ImagOn Ultra with water, thoroughly
saturate
- Place film on plate,
careful to avoid folds, if folds do appear lift film and
place down again, until it naturally lays flat, if it
sticks prematurely add a few drops of liquid soap to the
lamination water or follow instructions for Large
plates
- Finish as you would with
a standard lamination continuing from step #6
Bond the film to
the plate using a drying cabinet (5 minutes at
appr. 50°C) or a hair dryer, set on high
for about one minute per square foot

now ready for image exposure
WET LAMINATION for
Lamination Large Plates or more than TWO Layers of ImagOn
for the Layered Intaglio-Type Method
The Wet Lamination method
should always be used for applying more than one layer of
Imagon to a plate. Be careful to remove the Mylar layer, on
top of the Imagon film, between each layer
- Place plate in a
developing tray under 1/2 inch of plain water
Remove inside
peel-back layer (inside of film curl) from the
ImagOn Ultra. This can be done by prying off the
inner layer, but the easiest way is probably as
shown in the image; a piece of double-sides tape
on a table corner. A corner of the film sticks
to the tape and with some training the inner
layer be relaesed from the film.
|

|
Place film,
emulsion side down, in water above the plate;
The film will float on top of the
water
|

|
- Remove film and plate
together from water so that the film stays on top of the
plate. Grasp the edge and under the plate while bringing
the plate out of the water. Avoid grasping the plate and
Imagon film together when removing it from the water.
Wherever you do this the Imagon will stick prematurely
thus not allowing for re-positioning of the
film.
- Place the plate with
ImagOn floating on it on to a glass slab. There will be a
thin layer of water between the film and the
plate.
Quickly, gently
and carefully squeegee the film onto the plate
starting in the center and working out, being
careful not to push too hard and wrinkle the
film. It will want to stretch and wrinkle.
Slowly increase the pressure and repeat. Use a
6" squeegee with sharp medium neoprene rubber
blade. Repeat with increasing pressure until all
water and air bubbles are no longer
visible
|

|
Finish as you
would with a standard lamination. Bond the film
to the plate using a hair dryer, set on high, or
a drying cabinet. Drying time will be about 2
minutes per square foot or use a hot plate set
hot enough not to inflict a burn. Cover the
ImagOn plate with aluminum foil to avoid
exposing it to stray room light

The laminated plate is now
ready for image exposure
Lamination with an
etching press
Keith Howard described how
to use an etching press for lamination purposes in his book
"Non-toxic Intaglio Printmaking". Lamination can be done in
various ways. The right way to do it depends upon the sort
of film and for example the humidity. In dry area's it is
important to use much water during lamination. Try the
different techniques and choose the best one.
- Cut filrn slightly
larger then plate size
- Place degreased plate
(with alcohol) on clean glass slab, or any other hard
surface that does not absorb water.
- Spritz plate with
water

|
Spritz the plate
with water. Lay the film (mylar on top) gently
on top of the plate. Be careful not to wrinkle
the film. Use normal pressure for the press et
let the plate run through the press.
|

|
Put the plate on
the work table and trim the excess film from the
edges of the plate
|

|
Bond the film to
the plate using a drying cabinet (5 minutes at
appr. 50° C) or a hair dryer on the
backside of the plate, set on high for about one
minute per sq.ft area. (1 square foot =
