Pretreat solution quantity will vary based on thickness of the garment. Use the chart below as a guideline.
1:1 Mixed
Pretreat
Solution
> Proper pretreat volume for a garment should be determined by a garment's absorbency rate in
conjunction with using the Highlight-Mask Check Pattern to help determine driver ink settings.
> Don't forget that you have to define a surface of 14 X 16 inches [35 X 40 cm] with your pretreatment ma-
chine to weight the amount of spray, with a scale, after applying the pretreat on a T-shirt.
> For example, on a Schulze pretreat machine, you should enter a length of 13 inches and the full width
of 4 nozzles will be 17 inches. And then, calibrate the pretreat machine to spray 30 g on the garment.

HEAT PRESS SETTINGS FOR PRETREAT CURING

Pretreat
Solution
> Placing silicone based parchment paper over the pretreated garment while heat pressing can mitigate dried
pretreat buildup on the non-stick covers. Clean the non-stick covers on the heat press with a scrap t-shirt or
cloth after every 5 t-shirts if not using silicone based parchment paper.
