Once the
screen is dry you can now burn the image onto a silkscreen.

You
place your film positive face down on the back of the screen.
When doing a multi-color print you must have a screen for
each color you are printing. In this photo I am doing a three-color
print. To make sure the design lines up, I measured the same
distance from the top of the screen to the targets provided
(6") on all three screens. You then burn the image into
one screen at a time so make sure the other screens are not
in the same room while you are exposing one to the halogen
light. You can just cover them with a black cloth.

In
the following photos I will take you through the steps of
burning a one color print (you would do the same for a multi-color
print and measure the positives just like the photo at the
top of this page to ensure that the print could be registered).
In this photo you see a light attached to the wall; this is
a 500 watt halogen light. It is 12" from the light to
the black box right under it. Also in this photo is a screen
ready to burn an image into it.

You
place the screen under the light and over a black surface
(it is very important that it is black). The box I made fits
inside the screen and the mesh rest on it. This can be foam
or wood with black cloth so the light does not reflect up
from the bottom.

Place
the film positive over the screen (center is fine) face down,
but when you are doing multi-color, use targets to measure
from to ensure proper registration of all the colors. Note
the positive is reversed because this is the back of the silkscreen.
When you print the image will read correctly.
Then
you lay a piece of heavy glass over the positive (I use 1/4"
commercial glass approximately $10.00). The better the positive
is held tight against the screen the better the image. The
edges are crisp and clear and the image washes out easier.

Turn
the halogen light on for 5 minutes then turn off the light.
Make sure there is no other ultraviolet light in the same
room, or any other screens that have emulsion on that is ready
to be exposed. After you wash the image out you can bring
the screen out into the light and it will not matter.
Remove
glass and positive.

Now
you are ready to wash out the image by running water over
it until you see the image clearly.
Washing
the screen out takes about 5 minutes. First get both sides
wet and then just let the water run over the image until it
starts falling through were the image is. It will look white.
Again, do not do this in the sunlight or under ANY ultraviolet
light. Only when the image is clearly washed out can you bring
it into the sunlight.

When
the image is clear you can now take it out in the day light
and let dry.
Thoroughly
tape all the inside edges of the silkscreen with tape. You
can even tape the top part of the wood. You will see later
that this will make cleaning up very easy.
