So, we have rush for tomorrow, and only puff base. I can't seem to find the correct ratio of white ink to puff base anywhere, does anyone have experience with that base?

Well shoot, That PIB won't help you.
Back in the day the Union product was 25% base added to white.

we tested, and it ended up 2:1, base to white. It was kind of gross, but the end user loves it, go figure.

After looking at the meager Wilflex tech info, it kinda' appeared to me that this is truly a base meant to mixed with their various pigments for best results. Not like a puff "additive" for RFU inks

Yep. That’s what I understood last week. There is a Puff additive and there is a Puff base. The Base (from the spec given to me by Ray Smith at Wilflex/Union/Rustland/Polyone/Avient er whatever these days, was 20% puff base, 80% ink (for a puff screen). I gather that the "additive” is to make things more opaque or slightly dimensional but not really puffing. If I remember right.
BUT, like Sbrem, we ended up with probable about 40% puff base added (before I was able to get that info to the ink mixer/printer). For what we were doing and trying to achieve, it worked...but it still wasn’t all that extreme. We currently have a small 8'dryer, so that may have played a role.

I'm not so sure about that. My first few years I used a four foot Ranar Scamp dryer without even an enclosed tunnel, virtually just a panel suspended above a small belt. Puff was big then, and with the proper RTU inks from Union, it worked great!

Ours was extreme, to match what was already on the front. I prefer a suede base over puff, but we have no call for it at all...
