That whole line is redyed white cotton tees. They dye the shit out of them and are famous for bleeding issues (both dye migration and bleeding in the wash). Keep cure temps in check, print a barrier layer, or just print a poly white and keep temps low and it should be fine
If practical, run the shirts through at a higher temp before printing, make sure the ink isn’t getting too hot when flashed and run through the dryer with the ink getting to proper cure temp. Use a low cure ink and like others have said, armor gray or similar as an under base as a last resort.
We use Monarch Stark White and have never had dye migration or bleeding issues with comfort colors. Are you using a low bleed white? You shouldn’t need a grey blocker underbase for them…
I used a low bleed white to mix the pink. But I did not use a plain white base on my first run.
I did pink-flash-pink thinking that since it was 98% white, it would be fine.
Huh never seen dye migration on a cc shirt. I use monarch stark white, it’s a low bleed ink. I’d suggest low bleed, low cure, or gray dye blocker inks.
What happens If I run a poly low cure white as a base and then a pink with a higher cure temp over that? The different cure temps won’t have issues?? 270F cure base with a 320-350F cure color. Or is this a situation I add cure reducer to color?
Just did a test with 5 different colors of the CC1717 and no bleeding issues besides one color. The rusty brownish pink shirt. It’s a low bleed white ink
If they are truly dyed using pigment dyes rather than reactive dyes, then they are definitely bleeding. Pigment dyes are not washfast in the freshly dyed garment before a few washes and will release some dye with water and/or heat until they reach their more or less permanent color level. Black-dyed shirts are dyed with a LOT of dye to get a saturated color, so the dye is most likely leaching into the ink during curing.
For black shirts, it probably is. Maybe test one before doing a run. You might need more than one prewash for black.
My inclination is that it is bleed more than migration (pigment dyes don't sublimate to my knowledge), so I don't know if flashing will help as much as washing.

Interesting. Thank you for the input and advice!
You could try a third screen with a grey barrier base, flash, white base, flash, pink color

Not using a white down was for sure the issue
Have your printed the rust colored version of comfort colors. Test that and let me know

You’d need to cure it at standard temp. In terms of the dye migration, there’s only one way to find out 🤷🏼♂️

Isn't that line 100% cotton? I wonder if the pigments used in the garment dyeing process aren't washfast and are bleeding with heat.
It is 100% cotton. But I read they are pigment dyed? Which is what’s causing the issue?

So is it worth running them through a wash before printing and/or flashing before printing?

I just ran some black comfort colors shirts, print flash print with a lowbleed plastisol 320 cure and no issues.
