I'm familiar with Wilfex Bleed blocking grey, and apparently just a poly blocker doest work extremely well on comfort colors, but can it work (well enough)? Like does it block some of the migrating dyes of a comfort color? This is Brick and Crimson. Tough ones. We just don't happen to have any bleed blocker Ron hand and the customer popped in some surprise colors. Only about 20 of them tho.

We only use the one from Rutland Barrier base. I mix 15% white and add viscosity buster, NOTHING HAS EVER PENETRATED THAT BASE!
-
Use a barrier base. I've printed Comfort Colors with a p/f/p/f/p of Poly White on a 110M & still have had the dye migrate. We've used Rutland barrier base with great results, except it's like cement & needs modifier to make it more print friendly. We use One Stroke's Digital Grey Base currently which works just as well but with a better viscosity & just a bit more expensive. Never used Wilflex's barrier, but I'll venture to guess it'll block like most other barrier inks.

Same here. Rutland barrier base works great on the Comfort colors Pigments and reactive dyed garments.

I thought maybe it would still bleed. The Prod seems to think he's got it covered, but I don't think so. May bite us later. but in a pinch, waddia do?
I'm a firm believer in the Wilflex Bleed Blocking grey. Thats all we used at my previous shop and still do. Barrier I'm sure would be great also. Thing is, there's no time to order. Typical scenario. Had the order sit in here for a month, custy sent in some others at the last minutes. Guess what, Comfy color Brick, Blue Jean and Crimson in there.

They do have that new Armour BLOCKER . We have used 5 gallons with great results but its thicker than the Rutland and were rUnning it thru a little higher mesh to not blow the hand entirely. Dan the thing with bleed blockers is it does just that so I don't think you will have any post migration. issues.

We use a Rutland grey barrier base on performance wear and sweatshirts with a high poly content. As they say it’s like cement and needs to be diluted.
Dirkdiggler why do you add white?

Because its TOO DARK! Add the white and it will drop a few shades lighter, then you can print colors on top that POP!

Also with our mixture, it then prints as easy as black ink!

I just have to come back in on this and post on this again.
Ya know, we didn't have any bleed blocker left (or just not enough to complete this order) and he didn't use any. And I thought...he must be going to use straight Poly ink on this...and is why I posted.
He didn't use Poly or any bleed blocker. He used straight ICC Legacy white. So I leaned over to the operations Mgr and said..."We're probably going to eat these comfort color tee". I thought for sure they were going to bleed.
The print was as smooth as could be...and as bright a white as could be....and too my surprise. They didn't bleed AL ALL. The printer said, Ït's all about the belt speed and temperature and allowing them to cool once they come out of the dryer. Don't stack them. So we didn't stack them. Spread those boogers our all across the shop. That was on a Friday. Came in on Monday. No bleed.
Now, I've seen these comfort color bleeders bleed (even with bleed blocker) if not used thick enough. So I was very surprised to see they didn't bleed at all. That was a Crimson, Brick and a Charcoal grey. All three new known and notorious bleeders. I'm amazed..

Debbie Downer just reminded me that it took close to 2 weeks for my first red 50/50 disaster to rear its ugly head when I was just a tadpole.
Hopefully, your Comfort Colors, even though garment dyed, have dyes that are way more stable.
-
I hear ya Frog. I'm still thinking they may turn, BUT...I have a set of those sitting out in production that I'm watching..and checking now and then. It's been 12 days already.
-
Dan did he run them through fast or lower the temp and run them through slower? I always cringe when someone orders crimson especially.

To be specific, I don't know for sure unless I ask him as I don't pay much attention to a normal speed. I was there catching. I think (comparably), they seemed to be coming through faster...and hotter. They were pretty hot. Too hot to hold long and I was fanning them off, flipping them in the air several times per shirt as they came out. They were piling up so I'd say he was running it really fast but at a very high that to get it to reach cure temp...and then out the end. Just checked our samples and still today, no bleed.
-
Thanks for the answer. I tried it both ways with straight poly but could've had my time temp wrong.
-
One stroke has a ELT-s white ink that is great for comfort colors straight print with no bleed blocker as it is a low cure ink, I've used it and also bleed blocker grey from wilflex when I use other white inks for top color..hey thanks Jason for the tip on adding white to the grey blocker I have some now from international coatings that seems a little to dark for top colors, I'll try that. I like the vintage look style print when I print comfort colors and If I can and the customer approves I like the bleed look.

Keep in mind, I'm not saying this is the right way, I'm not saying this is a better option. I'm just saying that I'm surprised at the outcome and was really wondering is someone had any feedback as to what's going to happen. Guess I can't tell until it hits us in the face. LOL. I think we are safe tho. Just don't know how.
