Do Printable iron on transfers come on clear “paper” so the image is the only thing you see?
I believe that if you just print on regular transfer paper, the background won’t be visible (unless you’ve intentionally made the background white), though whatever you’ve added will be somewhat translucent. The paper itself won’t look clear though… it’s just that parts that haven’t been printed on won’t transfer since there’s nothing to transfer. The transfer papers “for dark shirts” though have “colors” that will be very opaque so those papers are often used on non-white and light-colored shirts so the colors will show up well on colored shirts and dark shirts. In either situation, I think anything you don’t include intentionally won’t show up on the shirt after transferring though. HTH, Diane B.
