films, or Autotype Capillex films are direct photostencil films.
This is an easy, quick, and fool-proof method of preparing your
stencil. It is excellent for T-shirts with fine detail, as well
- In safe light
or in subdued artificial light, cut the film size required
(larger than artwork) for the job. Return remaining film immediately
to the original tube or box and seal in plastic.
- Thoroughly wet
both sides of the prepared mesh.
- Check to be sure
the film is dust-free, and apply the dull side of the film
to the underside or print side of the screen.
- With a light spray
(a window cleaner bottle is ideal) soak all "white" spots
with water. These spots indicate where the film has not adhered.
- Using a clean
squeegee, gently scrape off (Do Not Rub) excess water using
a light even stroke, from the SQUEEGEE SIDE OF THE SCREEN.
Blot (Do Not Rub) excess water on the underside of the screen
with unprinted newsprint.
- Allow screen to
dry horizontally in safe-light area with underside (print
side) of screen facing up. A fan will speed up drying time.
Do not use heat to dry the film. It will cause damage and
be impossible to expose.
- When completely
dry, remove polyester (clear) backing sheet before exposing.
The clear backing sheet is easy to remove from dry film. If
it seems difficult, increase the drying time.
or print side
Resistal, Autosol Fast, and Autosol Plus Clear are direct emulsions.
This method is quite a bit cheaper than using the capillex film,
but is not as fast and easy. All emulsions are supplied as two-piece
lit consisting of an emulsion base (large container) and a diazo
sensitizer (small container).
MIXING THE EMULSION
- Fill the sensitizer
bottle 4/5 full with warm water and shake until the sensitizer
is fully and completely dissolved.
- Pour the sensitizer
solution into the emulsion base and stir in thoroughly with
a plastic or wooden stirrer until you see no more streaks.
The emulsion is now light sensitive.
- Allow it to sit,
tightly covered in a dark place, for at least 1/2 hour once
sensitized, to allow air bubbles to escape.
- The emulsion is
now ready for coating onto a screen. Once mixed it will last
about 3 months, longer in the fridge, but keep it tightly
covered and out of light.
COATING THE EMULSION ONTO A SCREEN:
- Pour a
quantity for emulsion into the scoop coater, enough
so that the emulsion is easily distributed across
the width of the scoop coater. Any leftovers can be
poured back into the original container and stored
in a dark place.
the screen on edge tilted slightly away from you and
starting on the squeegee side, coat the screen with
a thin edge of the emulsion. Hold the coater consistently
and move in a smooth motion, being careful not to
nick the edges.
the same procedure and coat the print side of the
with a final coat on the squeegee side. If emulsion
coating seems uneven, then use a "dry scrap" on the
squeegee side and reapply. Always finish with a coat
on the squeegee side. 5) The screen should be dried
HORIZONTALLY and stored in safe-light or yellow light
conditions. Dry at a maximum temperature of 30¼C (86¼F)
Never use a blow dryer or other heat source to speed
- The scoop
coater must be washed with warm water immediately
after coating screens. Screen Strip will remove any
emulsion that has dried on. Care should always be
taken not to nick or gouge the blade of the coater.
AND HANDLING OF STENCIL MATERIALS
stencil materials should be kept at a temperature of 15
to 20¼C (59-69¼F) and a relative humidity of 55-65%.
should be handled under low wattage yellow light or subdued
artificial light only for short periods of time. The roll
or box of film should be kept closed and sealed after
use. Capillary films can be kept at room temperature in
their own container with the lid sealed. Shelf life is
12 to 18 months from the date of manufacture. Screens
coated with capillary film and stored in a safe light
area will have a shelf life of up to three months.
never be exposed to a temperature of 0¼C, or the freezing
point. Unsensitized emulsions have a shelf life of 36
months from date of manufacture. Sensitized emulsions
can be stored in their own containers for three months.
If stored in a domestic refrigerator, this time can be
doubled. Screens coated with direct emulsions and stored
in a safe light area will last six weeks to three months.
