Diluting the Pre-treatment Solution
Before applying the pre-treatment solution to a T-shirt, make sure you dilute it correctly with distilled or
purified water as described here.
Caution: If you do not dilute the pre-treatment solution, it leaves noticeable traces on the T-shirt or the
printed surface cracks after washing. If the pre-treatment solution is too weak, White ink does not adhere
to the fabric and the desired print quality may be poor.
When fixing ink with a heat press: Start with a 1:1 ratio of pre-treatment solution to water and test by
increasing the water up to a ratio of 1:3. If the printing area is letter-size or smaller, start with a 1:2 ratio.
If the printing area is larger than letter-size, start with a 1:3 ratio.
When fixing ink with a heat tunnel: Start with a 1:2 ratio of pre-treatment solution to water and test by
increasing the water up to a ratio of 1:3.
Before applying pre-treatment solution to the entire T-shirt, test it on a non-visible area.

Pre-treating a T-shirt with a Roller
To prevent colored T-shirt fibers on the roller from sticking to other T-shirts, use a different roller for each
color.
Note: Do not apply too much pre-treatment liquid; otherwise, the print quality may decline.
1. Fill the tray with diluted pre-treatment solution and dip the roller in it.
2. Spread out the T-shirt on a flat surface.
3. Squeeze the pre-treatment solution out of the roller by pressing it against the edge of the tray.
