I've got a job for 170 Black performance t-shirts (100% poly, C2 brand). My Union poly-1050 is just too thick to get a decent print.
I tried some One Stroke LB premium and got a nice print... but the whole dye migration thing has me spooked.
Can any one offer a suggestion for a really creamy white plastisol ?? ... something that would be appropriate for performance fabric.

I have had great results with Rutlands Super Poly white. I like it a lot better than the poly white I have used prior to it. We have ran every color of the rainbow of poly shirts with it and never an issue so far. Just did 750 maroon poly's last week. No migration at all.

Wilflex Epic Performance White. If you use it, keep some QEC Viscosity Buster on hand and add no more than 1-2% if needed. Before reaching for the buster, warm the ink (try this with the ink you have as well) stir well and keep it moving. This solves a lot of the problems that come up with thicker inks.

Thanks... can it be printed threw a 160 or higher mesh ?

Like the Wilflex you may need to put a little reducer in it. The poly T's are ink suckers so you may want to stay with the 160. I run 160 S mesh as the base screens on the poly T's. I used the Wilflex for a long time and it is great ink just a little thicker than the Rutland.

We have had a lot of luck with the International poly. No reducer needed needed even on cold mornings but sometimes add a just a little stretch additive. I usually run it through a 160.

International Coatings - Paramount white
It's their poly white, very similar to union poly white. Very thick at first then it prints like a dream.
-
i've only tried unions and wilflex, i prefer union - usable straight out the bucket. the wilflex is a touch cheaper - but hard like a rock .

The big boys use the HSA (high solid acrylics) for these. Ginormous learning curve and probably not worth it if this is a one time charlie. They dry in the screen in a blink. That said Rutland, Wilflex, and Sericol among others offer these.

Xenon Mustang White. Cures at 260 degrees. $72 per gallon. Xenon Reg White. Cures at 290 degrees. $50 per gallon. Both go through a 160 mesh no problem

I do those jersey all the time and us one stroke color max white. very smooth and i can print it through a 156 manually or a 230 auto easily.
absolutely no dye migration

Wilflex Performance White beats them all IMO, and I have tried ALL of them. Straight out of the bucket.

The Performance White is specifically designed for these type of fabrics. The Wilflex PolyWhite might be the most bleed resistant, but it is thicker and not as elastic as the Performance White.
Be on the lookout .... Wilflex is marketing a range of standard colors based upon this technology and will be released VERY. I have look at the inks and there are some real nice characteristics for printers needing a RFU solution in plastisol for performance wear and poly jersey printing. Additionally, Nazdar SourceOne is closing in on the color palette in our ImageStar Silicone offering.
The big advantage of using these is keeping the cure temperature below the potential sublimation point of the polyester dyes. Commonly used low energy dyes can be a real problem.
Tony is spot on with High Solids waterbase being a solution as well. However, you need to be concerned on the cure temps/time as most H20 systems need 330f for 2 minutes or more. Underbase gray technology for the HS is a good recommendation for the bad bleeders.

Xenon horse White. Cures at 260 degrees. $72 per gallon. Xenon Reg White. Cures at 290 degrees. $50 per gallon. Both go through a 160 mesh no problem
Has anyone used and confirmed these numbers Sonny posted? I would think if they are accurate it would be a game changer but I havent heard anyone saying they are running shirts at 260 degrees?
Wilflex poly is really good unions 1070 rocks but stiff as hell. Not much of a problem on an auto, a nightmare for manual.

We've had our best luck with the Rutland...

If you want to avoid migration at all, underbase with Rutland NPT grey barrier and a poly white on top. Nice prints.

With an ink as effective against dye migration as the Gray Barrier, why bother with another poly ink on top? Sure, I can buy the "better safe than sorry", but why not take advantage of the usual better printatbility of an ink not poly specific?
I print manually, so the unfriendliness of most Poly inks is especially noteworthy to me.
That said, almost across the board, whites have really improved in this regard over the years.

You can run standard top colors over a dye blocking base but they cure at higher temp and have different stretch properties so I like to run performance colors as well.

We use Wilflex Extreme regularly and have found- 156- 2 hits / Revolver / 1 hit out.
Or set up 2-156's - one time around and out. Gas dryer at 330 max. -netting approx. 300. (Normally 350)
Not so much blowing agent as Quick White and covers very well. Hope this helps.

What type of ink is that Trebor? Curious minds want to know.... ;D
-
SportsFlex Technology.....it something we have been working on for years. Put it into full production last year. It was about 8% of revenues. This year it will approach 30-35%.
-
is that sports flex tech. a silicon based ink with 2 parts and a dye?

He ran the horse white through our dryer(and printed it here). I didn't get to see the wash tests. It's a little glossy for my liking, they added something to make it that way so it works for athletic printing.
Also, I find it to be a little thick, I would prefer it to be a little thinner, you have to use a special thinner for it as well. You won't cure regular reducer in it, you need low-cure reducer.
Sonny, can you guys get me some matte Horse white?
