SK Light Cotton DTG Pretreatment PRT-DTG-WC

SK Light Cotton Pretreatment (PRT-DTG-WC) is a pretreatment for DTG printing on white and light cotton, including hemp and linen. Use it for colour ink (CMYK) prints with no white ink underbase. It leaves very little visible stain. Made in Thailand by S.K. Color & Chemicals.

What it is for

• White and light cotton, and natural-fibre fabrics
• Colour ink prints only, not white ink on dark fabric (for dark fabric use PRT-DTG-DC)
• Works with water-based DTG printers such as Brother GTX / GTX Pro / GTX Pro Bulk, Epson SC-F2100 / SC-F3070 and Ricoh Ri1000 / Ri2000
• Spray by hand or use a pretreatment machine

How to use

1. Mix 1 part pretreatment with 3 parts water (1 litre makes about 4 litres ready to use). Distilled or RO water is best. Shake well.
2. Spray a thin, even coat all over a clean, dry shirt. Do not soak it.
3. Dry completely before printing: heat press at 165–180°C for 40–60 seconds, or tunnel dryer at 145–160°C for 100–140 seconds.
4. Print, then cure the ink as the ink maker recommends.

These are starting values. Test with your own shirts, ink and printer before production.
