Pre-treatment application procedure
This section describes an example of using Pre-Treatment for Color Ink.
• "Pre-Treatment for Color Ink" is used undiluted.
• Lay the garment down on a flat spray table. Ensure that the garment is even and flat.
• Apply the pre-treatment with the sprayer. Apply an adequate and even amount. Remember that you
only need to apply the pre-treatment to the areas that will be printed.
• The standard amount of pre-treatment liquid applied is about 0.0105g/cm
2
(ex : 13g for A3-size
(297x420mm) printing area ). However, the optimal amount may vary depending on the type of the
garment. Test the pre-treatment process on a few pieces of white polyester garment first to
determine the amount of pre-treatment.
• Going in only one direction, use a plastic squeegee to help spread the pre-treatment evenly after
spraying. This also flattens any fabric fibers that may have risen due to the application of the wet
pre-treatment.
• Dry the garment. You can use a heat press, a blow dryer, or a heat tunnel. Do not dry your
garments in a tumble dryer. These dryers are full of lint, and because the pre-treatment is wet and
somewhat sticky, you will end up with lint stuck to the pre-treatment.
• Do not overdry white polyester garment. Wash fastness may decrease if over-dried.
• If using a heat press to dry the garment, use the following steps.
Put a sheet of heat press paper on top of the shirt.
Press with very light pressure (= Lowest pressure that can be set on a heat press) for 20
seconds.
• When using heat press paper, the paper may wrinkle and the paper wrinkles may be transferred to
the white polyester garment. We recommend replacing the paper every time.
Press with very light pressure for 20 sec
