Below is a list of the Frequently Asked Questions (FAQs) for the DTG Pre-Treat™ Paper. Please review this list before sending a question.
Q. Where can someone get an SDS (MSDS) Sheet on the DTG Pre-Treat™ Paper?
A. Click here to download the SDS (MSDS) Sheet.
Q. How should the paper be stored?
A. Best suggestion is in the area where you keep your Brother DTG printer. But it can be exposed to high and low heat without adverse effects. The most important factor is to keep the sheets tightly sealed in the original foil package.
Q. How long will it last once the package is opened?
A. After opening, keep the foil bag sealed. Keeping the bag closed to prevent evaporation of the liquid should allow the bag to be used for at least 60 days or longer. If the sheets are thoroughly wet they will perform as expected. They cannot be re-wet with water or even the solution you would use for spraying.
NOTE: It is best to flip the bag over regularly to prevent the fluid on the sheets on the top from drying out.
Q. If a piece is cut for a small section, how long before the left over section must be used?
A. Place the leftover piece back in the package immediately, seal, and it should be fine for at least 60 days. It will not re-wet if you let it dry and it should not be replaced in the package if dried or left exposed for more than a few minutes.
NOTE: If you are using metal tools (i.e. scissors) to cut the sheet, the metal pieces should be cleaned off to help prevent rusting.
Q. What is the storage time for unopened packages?
A. Unopened packages should least for about 6 months. The packages have a manufacture date, use the oldest inventory first.
Q. Is there an expiration date on the package?
A. There is a date of manufacture on the packages. Please rotate inventory.
Q. What materials can this DTG Pre-Treat™ Paper be applied to?
A. The product performs on the same fabrics as the spray pretreatment. Preferably 100% cotton to maintain a strong print. White ink will not work on 100% polyester or synthetics. When using white ink to print on blend garments you need to know the following. The percentage of cotton must be higher than that of the polyester or synthetic material, for example 80% cotton/ 20% polyester. This is because Brother™ GT inks are waterbase. When printing from a rage of 90/10 to 80/20 or less of a blend the white ink will retain its vibrancy and wash-ability will be very well. A blend of 50/50 will print and look good when wet prior to curing the GT inks but the quality and wash-ability will be poor. We don’t recommend 50/50 or higher when printing with white ink.
Q: Should the garment be pre-pressed before placing the pretreat sheet on it?
A. The fibers of the garments can absorb the moisture in the air if stored in an area with humidity. For locations like this, a short 5 second pre-press using a hot press (set at 356 degrees F) will help to remove the moisture from the fibers of the garment.
Q: Are there washability or vibrancy differences between different materials?
A. The appearance and wash durability is the same with a spray treatment or the DTG Pre-Treat™ Paper sheets. There will always be vibrancy issues with polyesters and white ink due to dye gas migration, but along as you stick to the “guidelines” above the wash ability/vibrancy should hold.
Q: Are there different types of paper for different colored garments or garment types?
A. Yes, there area DTG Pre-Treat™ Paper for dark garments (blacks, browns, dark green, dark blue,…) and for lighter garments (pastels and lighter shades). The dark garment sheets come in a package with a red label. The light garment sheets come in a package with a yellow label.
Q. What will be the issues if pressure or temperature or a cold press isn’t used? Will some cause vibrancy issues and others cause washability issues? Which will cause specific problems?
A. The pressure at each step is important to controlling distribution of the liquid, even drying and the ink curing quality.
The temperature has a range around it, but variations from targeted temperatures could have an impact on appearance and wash durability.
The cold press is used to get the liquid in the sheet evenly transferred to the fabric without drying out the liquid before it is transferred to the garment evenly.
A clean, flat and level platen on the heat press is important to even distribution and good finished shirt appearance.
Q. Why is it recommended that users where gloves and eye wear when using DTG Pre-Treat™ Paper sheets?
A. Some people are more sensitive than others when working with chemicals. Like the other pretreat fluids on the market, protected steps are recommended when using both liquid pretreat and our DTG Pre-Treat™ Paper sheets. We want everyone that uses our product to be safe. Please refer to the SDS Sheet for DTG Pre-Treat™ Paper and consult your physician should it be necessary.
