Starting out on the sublimation mug-pressing adventure. I've a got a second-hand mug press with no instructions - a Xpres 1000 - it weighs a ton so feels like it's a good bit of kit. Looked on the internet for instructions but drew a blank. Anyways, is there anyone else out there using the same bit of kit? Any tips or advice for someone starting out - such as whether to use a dummy mug or not, settings, or anything like that?
