Please note: The heather colorways are not made of 100% cotton face yarn. Please do your own testing prior to screen printing. When printing on our Camo Colorways it is important that the garment DOES NOT reach 320 Degrees when flashing or drying. Our Camo Colorways are a Water Based Print on 100% cotton fabric surface. At 320 degrees you risk ink migration to your print. It is recommended to use a Poly Blocker base, and low temperature curing inks to stay away from 320 degrees.
