We've printed plenty of the rally towels and if there going to use them for the players, I would use waterbase ink, and if they are just for fans to wave around plastisol will work fine as they are not using them to wipe sweat. If you do use waterbase inks reduce temp in dryer and let them run thru slow almost like you would discharge inks...you may have to run them thru twice. Other than that very easy to print
