What is the best way to to imprint tan 100% woven polyester fishing shirts? Designs are primarily black with a spot of red and green. I was thinking of screenprinting the black designs and doing heat transfers for the 2 spot colors. The fabris is quite thin (and slippery). Or would it be better to do plastisol transfers for all rather than direct printing? I am concerned about the heat both in flash curing or the heat press damaging the fabric. Not inexpensive shirts and don't want to screw this up. Because the shirt color is a light tan, I am not really worried about dye migration. Any advice?
