Opportunity is missed by most people because it is dressed in overalls and looks like work. - Thomas Edison
nope, here is how I would run it....thin your white ink back for your UB, probably 60 white 40 curable reducer, maybe 70/30. Play around with that. then print the solid white with a standard white and boom...you are good to go. With those shirt colors this will work perfect...darkers colors might not let the white cover as well.
