See the square (where it pressed) looks faded compared to the rest of the shirt. I am hoping that's normal. Press is set at the temp required for the transfer.
Don't worry about it, it is simply the moisture being removed from the shirt. This is most noticeable in red, or in your case orange t shirts. If you are selling these, simply print something up that informs the customer to wash all shirts before wearing. Once washed, the square that appears faded will be removed, and will no longer be noticeable.
