at 200 degrees Celsius for seven minuets as instructed, but after pressing I have noticed that the tape marks are appearing on the blank after the paper has been removed .
I have shown an example of what I mean in the pictures .
I wondered if it might have anything to do with the heat tape needing replacing as it is quite old, or failing that lowering the temperature on the press?
I just wondered if anybody has experienced the same thing and have some advice as to what I might be doing wrong
