Printing white on Tye Dye... Bleed Blocker base or No?

[XG Print]

Hey.  We don’t get the chance to print tye-dyes often but this is the blue Jerry tye-dye with a white print. Do I need a bleed blocker or just P/F/P using Joes Poly white. Thanks guys.

If you have time, I would advise proper testing..

I have only printed Tie Dye from San Mar, and "homemades" using the procion dyes from Dharma Trading, and have apparently been lucky as I sometimes didn't even bother with low bleed, let alone poly, or the really heavy artillery specialized blockers. I have printed them both before the dyeing and after.
That said, Robert's advice to test if possible is certainly good advice. He's probably seen a lot more than I have.

Ive had success in the past using a bleed blocking gray base.

This has been my experience as well.

As far as cotton goes, I've never had an issue with tie dyes, and always an issue with cheap camo. 
Murphy might reverse the situation now that I said that.

We always use Poly on tie-dye t's as a default. However we have printed Low Bleed accidentally before & didn't have an issue. It all depends on the garment & dye process. But if you ever print Comfort Colors, always use a bleed blocker base. They're the worst.
