I am having some issues with the coasters I have tried multiple setups between 175-185 and 55-60 seconds it doesn't seem to make a difference. I have getting spots on the coaster that look to have peeled off and are stuck to the transfer paper. I use teflon paper as well. The reason I say it has peeled it because the park that is left on the paper is shiny as if it has pulled the top of the coaster off.20201130_195041.jpg
