Pretreatment
What Pretreatment does.
Preteatment is a primer/bonding agent that is
only necessary when using white ink.
(MSDS Ingredients list available).

Required tools
A sprayer that can spray a fine mist, A
Wagner HVLP (High Volume Low Pressure)
sprayer is recommended, you can also use
a Hudson sprayer that will deliver a fine
mist.

Pretreatment

The AnaJet Pretreatment Booth will allow
you to move the pretreatment indoors,
away from wind, rain and cold. It keeps
the undesirable spray mists under control,
by venting outside with the provided
exhaust tubes, so the operator can
concentrate on spray operations.

The twin exhaust blowers force all your
mists through a multi-stage filter system
and then outside. Swing doors allow easy
loading of garments.

Pretreatment
Application Procedure
Mix the pretreatment with distilled water at a
1 to 1 ratio

Apply Pretreatment in slow EVEN passes.

Since the pretreatment has a white caste
when wet, look for an EVEN grayish wet sheen
across the garment.

If the pretreatment soaks through to the back
or begins to run or drip you are applying more
than you need.

Going in only one direction even out the pretreatment using a card
squeegee to assure EVEN coverage.

Pretreatment
Drying options
Line dry, Flash Dry, Conveyer dry, or heat press by hovering
the heating element above the garment.

*Note: When drying the pretreated garment with a heat
press, be sure to hover the heating element above. If you
clamp the press down, you may cause the pretreatment to
glaze as shown.

Storage
Once completely dry, shirts can be
folded and stored until needed.

Pretreatment
Effects of poor pretreatment:
In this case the pretreatment was applied unevenly with the lighter areas
allowing the white ink to soak into the fabric causing a mottled appearance.

White Ink Pigment Separation

Be sure to check the manufactured date
on your white ink cartridges. White ink
has an expiration date of 6 months from
the manufactured date.

Every few days remove the white ink
cartridges and give them a quick
shake.

10


Since the titanium dioxide pigment in
the white ink is so heavy, when the
white ink is not used for a few days the
pigment may begin to settle in the ink
Ink tubes.
Pigment

Before printing with white ink check the
white ink tubes where they enter into the
print carriage. If they appear milky or
bluish the pigment has settled and you will
need to advance past this settled ink.

11


If the pigment in your white ink has
settled, a good way to advance past
this settled ink is to print a square of
just white ink underbase. Use a
setting of Heavy Drop Size, Level 3. You
will see when the printing begins that
the white inks appear milky and grey
but as the print continues the white
ink will become stronger. When the
underbase is satisfactory press the
cancel key. This process will advance
just the white ink without wasting any
CMYK ink. You will then be able to
print with a strong white underbase.

Fabric Fibers

The image above shows a close up view of the fibers of a standard t-shirt. To
achieve the best results when printing it is necessary to flatten these fibers.

Fabric Fibers
The images below show the results of printing when the fabric fibers have
not been pressed down.

Fabric Fibers & Heat Press Settings
To flatten the fibers of a pretreated garment place it in the
heat press and clamp down for about 5 seconds. A higher
pressure setting may be necessary to flatten stubborn fibers.

After the garment is printed, place it on the heat press and
hover the heat element over the garment by approximately ½”
(15mm) for 15 seconds.
(This procedure allows the layers of ink to set up before
applying pressure, this keeps the white underbase layer from
pushing up through the color layer resulting in fading of the
image.)

Place parchment on the garment and clamp down the heat
press with medium pressure for 90 seconds at 330˚F, 165˚C.

15


White Ink and Polyester Fabrics
When printing on blends of cotton
and polyester keep the following in
mind. Since the ink will not adhere
to the polyester fibers in the
garment the underbase will not be
a vibrant and this will in turn lead
to the colors also appearing muted.
The higher the polyester content in
the fabric blend the greater this
effect will be.

This becomes even more
pronounced after heat pressing.
