Unexpected graininess

I love sticker mule their products are fabulous. However, this order for me. The artwork probably wasn’t clear enough and sticker mule was kind enough to credit me the order and they helped me try to tighten up the artwork and resent it however, it’s just not good enough for public use I appreciate all the help and I’m going to have to just redo a design for this. That’s a little more clear. Thank you again for
