Light colored garments (that do not require white DTG ink) do not require to be pre-treated. However dark colored garments (that need white DTG ink) require to be pretreated for optimal results when printing and beyond. Pretreatment solutions are available for both light and dark colored garments and ensure excellent washability of the printed garment (colors don't fade and fibers don't unravel); softer feel to the printed garment and brighter print colors.
