I just went and bulled my way through it (ICC profiles be damned!

).
Here are the print settings I used (Texprint XP profile for SubliM):
The image below shows what the print comes off the printer looking like. Had to use an 8x10 size because my printer doesn't do edge to edge on 8.5"x11" sheets; This stuff really needs to come in a roll, but judging by the per sheet price, I dread to think what a 24" roll will price at.
Used a 100% Organic Cotton T in Sport/Heathered Grey.
One thing I haven't seen mentioned is how nice it is to align these prints with the clear plastic backing... the image shows through nicely for centering.
These are the press settings I used (from a discussion I read earlier in this thread):
...and below is the result. After pressing, there is also some kind of faint chemical odor that I can't quite place (almost like a Windex smell?)...
I used the color chart that I print on every substrate the first time, knowing that the lighter colors would lift, which will allow me to reference just how light is "too light" in the future. There is a definite 'hand' to the print, not dissimilar to heavy screenprint.
I'll run it through a couple loads of wash and report back soon.
