Plastisol transfers (cold peel white) on Poly Ripstop?

[Frog]

I have no samples of the material, so I can't just merely try some before taking on the job.

These are weird back packs that until I have one in my hands, could not tell the client whether I could direct print it. So I am keeping transfers as an option (design will not allow cad-cut)

Does this stuff bleed badly, or does it act a lot differently than jerseys? It is red.

Haven't done any 'Poly ripstop', but, use polywhite ink for the transfer and try one out.
Mind the temps.
Not sure what else to add. We've had good success on all sorts of materials
with the poly-blocking ink. Regular ink, not so much.
Fear the red! 
Best of luck.

The only Poly specific ink I have is my sample of Nazdar's Silicone, but from what I understand, it's strictly direct print, not for transfers.
Best I can do on the transfer ink is low-bleed, and yes, I have and use the powder.

[Chadwick]

Well..you've printed jerseys, so whatever white works there should be all good.
I feel no shame using the powder glue.
When I get it right, the rookies are bored.

Let one sit overnight, if you can.
Bleed isn't always immediate, as you know.

* I know none of this helps in your current situation, but what the heck are you gonna do?
Go for it, or pass.
Cheers.
