Fix the pre-treatment liquid with the heat press.

Note:
You need to press the fibers flat to produce even
whiteness. Use a heat press to fix the pre-treatment
liquid since the fibers are not pressed flat in the
oven.
Fixing the Pre-treatment
Liquid (Heat Press)
Use the heat press to remove creases from the T-shirt
and to fix the pre-treatment liquid. Because the oven
does not press the fibers down, the printed surface
does not become even which causes creases and
unevenness in color. When fixing the pre-treatment
liquid by using a heat press, place a heat-resistant
release sheet, such as silicone paper, between the
T-shirt and the surface of the press to prevent the pre-
treatment liquid from sticking to the surface of the
press.
Fixing conditions
As the optimum conditions vary depending on the
amount of pre-treatment liquid, the following values
are only a guide.
Temperature Time
130 ˚C 60 seconds
*1 The optimum conditions vary depending on the type of
heat press such as the manual adjustment type. Be sure
to test the ink fixing result in advance to find the right
pressure.
*2 If the application area for the pre-treatment liquid is
larger than A4, it may not dry even after 60 seconds. Try
extending the time up to 90 seconds while checking if the
pre-treatment liquid is dry.

Important:
O Make sure you dry the pre-treatment liquid
thoroughly. Insufficient drying time may cause the
print quality to decline.
O Do not wet the T-shirt or leave it in a humid
location for a long time after fixing the pre-
treatment liquid. White ink may sink in the wet
sections and cause unevenness in color.
If the T-shirt is left for an extended period of time
in such conditions, press for 5 to 10 seconds to dry it
just before printing.
Note:
If traces of the pre-treatment liquid are visible, try
washing in water; however, the effects depend on the
material of the T-shirt.
Uneven print results
Due to the nature of this type of fabric, you may notice
uneven colors when printing on polyester (see below).
Using a higher temperature setting when fixing the
pre-treatment liquid may solve this problem.
