Hi - I have previously used BMS balmoral mugs with Ink Experts paper and heated to 180d for 100secs. (Apologies for my non technical lingo) I have never had an issue with this. Due to the shortages, I have now purchased Balmoral mugs through Coral. I am now getting a print mark of where my paper has been wrapped around the mug with the pattern of the heat element wrap on that area? I have tried adjusting my time and temp, but nothing i do is making a difference! help please! Many thanks in advance. Image attached.
