We have started using the larger 13oz bone china mugs but having big problems with the positioning of template being a more fuller mug. We find that we cannot get straight sides to the artwork when paper pulled tight and when we do think it is then we get a blow out to the bottom of the artwork as no doubt the paper is not as tight as it should be. We are using a mug press rather than oven. Any advice on perhaps needing a tapered artwork (rather like latte) or whether there is some other trick to getting a perfect print? Thank you. Olly
