For spot color like solid black I would suggest you use either Imageclip for laser or Imageclip for inkjet. They are both self weeding so you will not have problem with polymer window or box on gold shirt. I have pressed on gold shirt and other vivid color shirts without any issue. Try sample first before you make a decision. Tshirtsupplies sells small sample quantity.I had thought of that option also. I just thought it might be easier to just to it myself. I guess I will wait and see if any one else has any advise and go form there. Thank you.
