Dear ForeverCustomer,
regarding the silicone paper, I would recommend to remove the paper after the shirt cooled down. Seems like that the silicone paper is not suitable with our papers for removing while it is still hot.
If you can see a background on one side of the image, I would guess that the pressure of the heat press is not even.
Try two times the same design, one turned 180° to see if the heat press is causing this.
Let me know if you need further help. You can also contact us via support@forever-ots.com
