I suspect that my digital reading on my heat press is off, on my eBay bought press, yes my eBay bought press. I have my teflon sheet taped to the top of the heating element. Here's my question...what is the best way to get a accurate temp reading using a IR temp gun? Should I aim it at the bare underside of the element minus the teflon sheet? Or can I just aim it at the underside with the telfon sheet attached? I have been trying to get a reading on the actual vinyl after applying it with heat, too much temperature fluctuation to have anything to go on. Any advise sure would help me out. And yes, I am planning on buying a more reputable brand of press in the future. But this is where I am right now at the moment. Thanks!
