DESIGN
5
Create design on computer.
For multicolored designs, separate
colors into different layers.
TIP: Not all designs need to be created
on the computer. Be creative by drawing
freehand on your transparency.
1. CREATE DESIGN
Print design in black on Yudu blank
transparencies. For multicolored designs,
print each layer separately.
Print on dull side of transparency. A
moist finger will stick to dull side of
transparency.
TIP: For multicolored designs, you may
find it helpful to create registration marks
on each layer in the exact same spot.
This will allow you to easily line up layer 1
and layer 2 later.

cotton blend, and similar fabrics. Yudu water-based inks are
water soluble and easy to clean up.
OTHER MATERIALS TO TRY
-Wood
-Paper
-Porous fabric
CAUTION
Printing on materials other than textile fabric may yield
different results.

2. PREPARE SCREEN
TIP: The back of your screen is completely
flush with the metal edge. The front is
slight lower than the edge.
TIP: You can use a spray bottle to wet screen.
TIP: Run squeegee up and down back and
front of screen to remove excess water.
Spray the screen with water. It should be
completely wet, but not dripping.
Remove the emulsion sheet from the
black plastic bag in a dimly lit area.
TIP: There are two sides to the sheet, one
shiny and one dull. If you can’t tell which
is which, wet your fingers and touch the
corner. The sticky side is the dull side.
TIP: Center the emulsion on the screen. Do
not allow mesh to touch anything while
applying emulsion.
Apply the dull/sticky side to the back of
the wet screen.
Make sure the screen is clean and free of
dust, lint, and oil.
All screen preparation MUST be done
on the back.

Adhere transparency, printed side up,
to the glass on the Yudu machine using
clear tape.
For single color designs, go to "Exposing
Screen" on page 8.
Tape second design layer to second registration
panel, stacking the images, and ensuring it is
registered with first layer. Repeat for each
design layer.
When design layers are secured to registration
panels, remove all but the first panel.
5. MULTICOLORED DESIGNS:
Press light table button.
4. SINGLE COLORED DESIGNS:
Place first registration panel on
registration posts.
Mount first design layer to registration
panel with clear tape.
Run squeegee over the shiny surface of
the emulsion.
TIP:Inspectfront ofthescreen for anybubbles ordry
areas. Dry areas will have a spiderweb pattern. Use spray
bottle with water to lightly mist any dry areas. Squeegee
both sides of screen to eliminate excess water prior to
drying. Dry edges of screen with a paper towel or cloth.
Place screen in drying rack of Yudu machine.
Press fan button to begin a 20 minute drying
cycle. The fan will stop and the machine will beep at the
close of the cycle. In drier climates the screen may dry
after as little as one cycle. In more humid climates the
drying process may require several cycles. For humid
climates you may blot moisture from the underside
of the screen with a dry cloth towel and/or squeegee
excess moisture from the screen to speed the drying
process. Test for dryness before moving on to the next
steps. After emulsion has dried, remove plastic film.
TIP: A hair dryer can be used to accelerate the
drying process.
TIP: Leaving door open while drying will speed up
the process. Repeat the drying process if necessary.

Add extra weight to top of platen to
ensure proper exposure (approximately
5 lbs). Using up and down buttons on
timer, set exposure time (approximately
8 minutes).
Press exposure button.
WARNING: Turn off machine for 1 minute
between exposures to allow unit to
cool down.
For multicolored designs, use new
screen and repeat exposure, wash, and
drying steps for each artwork layer.
When machine beeps and exposure light
turns off, remove weight, platen, and
screen from machine. Exposed emulsion
will turn from green to blue after
exposure. Design will remain green.
Wet both sides of screen with COOL
water and let it sit for a minute. Spray
screen with cool water to remove green
emulsion from design area. It may be
necessary to gently rub both sides of
screen by hand or use a soft sponge to
remove emulsion in detailed design areas.
Place screen front side up/emulsion side
down on registration posts. Place platen
on platen posts, foam side down, on top
of screen.
After emulsion has completely dried,
remove protective plastic sheet from
unexposed, emulsified screen.
Blot screen with lint-free towel. Place
screen in drying rack.
TIP: If plastic sheet does not remove
easily, the emulsion is not dry.
Press fan button.
It will take one drying cycle or more for
screen to dry. Touch screen with fingers to
make sure it is dry. A hair dryer or fan may
be used for additional drying.

TIP: Use Yudu Blockout (sold separately)
or small pieces of tape to fill any holes,
scratches, and registration marks in emulsion.
TIP: When adhesive sheet is no longer
sticky, peel off and replace. (Adhesive
sheets sold separately. )
TIP: For large open areas of design,
you may find it necessary to be more
generous with ink.
TIP: Hold lid up at a slight angle while
flooding screen. Make sure material is not
touching the screen before you flood image.
TIP: Material should be completely
adhered to platen with platen adhesive
sheets to keep material from shifting.

For multicolored designs, change
screens and repeat flooding and printing
steps for each color. Design must be
dry to the touch before printing next
layer. Do not remove article from platen
between printing different colors or you
will lose registration.
Allow ink to dry on article.
TIP: To keep ink from drying in screen
while in use, lightly spritz with water.
9. HEAT SET INK

excess ink from screen and rinse screen
thoroughly with water. Do not allow ink
to dry on screen.
TIP: Ink can be reused by scraping
excess back into container.
TIP: When using light ink on a darker
material, pull ink across screen multiple
times before lifting lid.
TIP: When using the same screen design
for multiple objects, flood the design on
the screen with ink to prevent drying out
until next use on same project.
WARNING: Do not allow ink to dry
in screen. This may damage screen.
Remove dried ink from screen by using
