In DTG printing, 100 percent ring-spun cotton is your best friend. Among these garments, some will print better than others. You need a tight weave and smooth fabric surface for the best finished print. Experimentation with new brands and styles is a must.
You are not completely limited to 100 percent cotton, however – it’s difficult to find hoodies in a range of colors that are 100 percent cotton. But a higher cotton content garment such as a 90 percent cotton/10 percent polyester, or 80 percent cotton/20 percent polyester will give you a fully acceptable print. Going down to a 50/50 blend will likely produce a garment that you won’t be comfortable providing to your customer.
