Manufactured by STS in the USA. Drop shipped directly from STS in Florida — not warehouse-aged inventory.
Precise color reproduction with vibrant saturation on both light and dark garments using pretreated fabric.
White channel delivers the high-opacity base layer needed for vivid CMYK colors on dark fabrics. Critical for dark garment DTG results.

FREQUENTLY ASKED QUESTIONS
Frequently Asked Questions — STS Replacement Ink Bag for Brother GT-541 / GT-782
The Brother GT-541 is the GT-5 series (single printhead). The Brother GT-782 is the GT-7 series (dual printhead for higher print throughput). Both use the same 500ml ink bag format, so this product is compatible with both. Confirm your model before ordering.
The GT-541 / GT-782 (GT-5 / GT-7) is an older generation than the GT-3 and GTX series and uses a different 500ml bag format. The GT-3 uses 380ml GC-30 bags. The GTX uses 700ml bags. Do not interchange ink bags between printer series.
No. STS GT-5 replacement ink is a virtual match to the original Brother GT-541 ink. Drop it in exactly like OEM — no purging, no profile changes, no downtime.
Heat press: 356°F for 40 seconds at light to medium pressure. Conveyor dryer: bring the ink surface to 330°F for 30 seconds. Use a laser thermometer to verify actual surface temperature on your specific garments. Always test before production.
STS recommends using their DTG pre-treatment solution for best results. Pre-treatment is required for printing on dark garments and strongly recommended for all garments to ensure proper ink adhesion and wash durability. Without proper pre-treatment, prints may crack, peel, or fade prematurely after washing.
Correct. All DTF and DTG ink products are non-returnable. Please confirm your printer model and the correct ink format before ordering. Call (512) 454-0505 or email [email protected] with your printer model if you have any doubt.
