Print 'em all the time here. Nothing special needed really, a fast flashing white helps out for sure though.
If you're seeing garment scorching before the ink gels you can:
1.make sure the flash is level to the platen and at just the right height
2.use extra tack/smaller platens if need be to keep the shoulder seams off the platen and out of the flash zone
3.add something called "flashing powder" to quicken the flash times of your ink
I think with all the blends we print on, not just tri-bends, getting a super smooth white is pretty damn hard without dropping a crap ton of ink on the shirt. We get close but the last run of anvil recycled Ts I did I was scratching my head about a better way. It was a choice between a slightly rougher hand and slightly less opaque print but less ink on the shirt and a fully opaque, smooth print with a bit too much ink. For the most part though, we're printing for a slightly vintage look on tri blends so it's easy going.
