Not sure about a print shop, do they do them?? i always used water slides for models when I was growing up. You can buy the slides, clear or white backing, at most hobby lobby stores or hobby shops. Printing is another story though. Some printers print dark and righteous on water slides, others don't. Ive had amazing success and terrible outcomes using different printers over the years. Once you get them printed, you need to spray them with sealer, they sell that at the store too. I think its basically hair spray lol.
