- When applying pretreatment to the garment, make sure to apply it as evenly as possible
- A good starting point is 15-18 grams per 14″x14″ area.
- NOTE: 18-26 grams may provide you with better wash ability and white optical brightness.
- Test to find your best laydown for the garment you are pretreating.
- Application amounts will vary based on the weight and quality of the garment being printed.
- The heavier the garment, the higher the amount of pretreatment needed.
- The darker the color, the more pretreatment is required.
- The lighter the weight of the shirt, you can usually reduce the amount of fluid applied to the garment.
- The lighter the color of the shirt, less pretreatment is usually required.
- DO NOT USE on white or natural colored shirts.
- Always use a high-quality garment that is ring-spun with a tight knit weave.
- The smoother and tighter the weave, the better your final DTG print.
- Set your heat press to 330F
- Cure time: 30 seconds or until dry. You might try two 20 second presses.
- Use brown KRAFT paper for best results. Teflon can result in a glossy sheen. Kraft paper should be easily removed and not stick to the shirt when peeling. Sticking will result in fibers sticking up resulting in non-smooth white prints.
- Pressure setting: Heavier pressure can be used and will help press/mat down fibers during the drying process.
- DO NOT allow cover sheet to remain on garment after pressing or crystallization can occur as pretreatment vapors cool.
STORAGE OF GARMENTS
- Pre-pretreated shirts can be done ahead of time. Try to use them as soon as possible. It is not recommended to go more than two weeks after pretreating before using.
- Always re-press the garment for 5-10 seconds with light pressure if they’ve been stored for more than a day.
- The shirts will collect moisture, and moisture is the enemy of good pretreated shirts.
- ALWAYS MAKE SURE YOUR SHIRTS ARE MOISTURE FREE BEFORE PRINTING.
- DO NOT OVERHANDLE the shirts. Touching, bending, folding, throwing shirts around will damage and break the pretreatment down on the shirt. For the best results, try not to “manhandle” the garments prior to printing.
