Although I don't like pretreating light shirts I have started doing it because the difference in washability and print is like night and day (FastColor is also very forgiving compared to dark shirt pretreatment). Here are some pictures, though poorly taken by myself they do highlight why I like FastBright. this was done on a T-jet2, Gildan G2000, print mode photo 360 HS and is kinda grainy because I blew it up. The left half of the shirt has nothing on it while the right side has FastColor.
