Hello,

It should go away after the first wash. How much pressure did you use? By the sounds of it, I think you may be using too much.

The "marks" are caused by the transfer paper. Sometimes they go away as the t-shirt cools, and others need to be washer first. Setting the time to 12-15 sec is a good idea to give you a better imprint, but would not effect the "marks"

Decreasing the pressure will though. I would set the pressure so it takes a little force to close the press (just a little) Don't force it.

I currently am using a Hix clamshell press for my shirts and have the setting on 6.5

Hope this helps.
