I'm a designer of several decades and I know how to prepare artwork, and how it will print. This company's art dept. is UNREACABLE, you cannot speak with them, you have to go through polite representatives and/or send numerous notes after declining incorrect proofs, which ap[parently no one reads. They altered our artwork without permission and for no technical reason. I get that they likely think they are good at production (and design...) but the things they did caused us to have to find another vendor - and we then quickly, got the job done without changing our artwork and for half the price. If you're producing anything printed on paper or magnets. We recommend StickerYou.com. For what it's worth, the mugs came out fine:)
