If you are using a heat tunnel to fix the ink, you must use a
heat press before printing to remove creases from the T-shirt and
to fix the pre-treatment solution. Always place a heat-resistant
release sheet, such as parchment (silicone) paper, between the
T-shirt and the heat press.
Note: Do not wet
the T-shirt or leave it in a humid location for a long time after
fixing the pre-treatment solution, or White ink may absorb into the
wet sections and cause poor print quality. If the T-shirt is left
for an extended period of time in a humid location, press it for 10
to 25 seconds with parchment (silicone) paper just before
printing.
The fixing conditions vary depending on the amount of
pre-treatment solution used. The following guidelines are
approximate.
Note: If the
pre-treatment solution is not completely dry after the suggested
amount of time, extend the duration while carefully checking if the
pre-treatment solution is dry. Make sure the T-shirt is completely
dry before loading it for printing; otherwise, the print quality
may decline.
