Diluting the Pre-treatment Solution

If you are applying a pre-treatment solution to a T-shirt, you may need to dilute it with distilled or purified
water. Dilution and the necessary dilution ratio depend on the pre-treatment solution, the ink used, and
the device you are using to fix the ink.
Cotton pre-treatment
Caution: If you do not dilute the cotton pre-treatment solution, or it is not diluted enough, 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 standing fibers may not be adequately flattened,
resulting in uneven print results.
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.
Polyester pre-treatment
When printing with White ink: Use the solution as-is without diluting.
When printing without White ink: Dilute the solution using a 1:6 ratio of pre-treatment solution to
water.
