Hi Tweat,
I've done at least a thousand shirts or more with the sawgrass and haven't had any problems. Digital Art Solutions and Great Dane Graphics have put together some good artwork to use for all DTG printers. They use corel 8 cv colors and if you print a test of all the colors on white t-shirts to use you'll be able to get the results you are looking for. Some jobs go to the the screen printer and some go to the DTG but the costomer gets to see samples of both processes and makes the decision. Talk to Mike in sales at Digital Arts Solution and he will be able to help you. Good Luck, Rick
