Fixing Conditions (Heat Press)
The conditions under which you must fix the ink with a heat press differ between White ink and color ink.
Make sure that you meet these conditions for fixing the ink.
Optimum conditions vary depending on the type of heat press. Test and check the results in advance to
determine the correct pressure.

pre-treatment solution is dry.

Note: Due to the fabric characteristics, it may discolor from the high heat being applied during ink fixing.
If fixing is applied at too high of a temperature, and for too long, or under too much pressure, the printed
color may be too thin or traces of the heat press may remain on the fabric. Test and check the results in
advance to determine the right conditions.
