iron All dark is also called everlast for darks.Yes to everything Joe has said. Look up "jetprosofstretch and claria ink", also search "JPSS claria" those searches will return threads with photos of printed and washed shirts for you to see.
For dark shirts, Ironall Dark or JetWear. Ironall Dark has been used successfully with Claria ink, but you may need to ask if anyone used JetWear with Claria yet, or be the first to try it.
If you look up "pigment claria ink" (Claria is not pigment - but those search terms will return the proper threads) read the threads to learn the difference between the two inks.
Good luck to you....
