Hi there, I am at the end of my tether printing mugs. I always make sure I tape the print on the mug tightly and then put a layer of paper over the top before heating. I then clamp the mug in the press (DK7) and when I open it the paper has creased and the mug has a streak on it. I think I've got the pressure right (medium) but I don't know why it's doing this. Can anyone please give me some advice as I'm throwing away as many mugs as I'm selling at the moment! Thanks in advance for your time, Jules.
