You can print on 100% cotton, 50/50 poly/cotton, triblends, and other natural fibers such as canvas and bamboo.
When you print on anything with 20% or higher polyester, you'll want to pay attention to the length of time you're applying heat to the garment when pretreating and doing the final cure. I will typically cure the pretreat with a pause in the middle of the required time to give the garment a chance to breathe and will have a longer hover time and less press time during the final curing phase when using a heat press...both of these methods help battle against dye-migration.
Not all tri-blends are made equally so you'll want to test printing on different brands before offering them to customers. I prefer using Allmade triblends with DTG the most with Bella Canvas as a close second choice.
