W.O.W. WB Discharge--Picks up on underside, skins over, and fouls my images...

[Itsa Little CrOoked]

So why no Fixer N?? Do you mean it isn't necessary with the CCI bases? I thought it was designed to enhance wash fastness, so I've been using it in all my WB Pigmented Discharge, and straight WB jobs. I don't use it in straight discharge jobs, meaning non-pigmented.

We use it in every color but the white and discharge base. I have been told by two Reps that there is no need to add it when asked so we never have. We have not had any issues so far.

we still add some fixer en, we probably don't need to, but we still do for covering all bases. I actually ran an  inhouse line run 2 weeks ago without fixer, fist wash and dry looks just as brilliant so this will be a time test and we will continue to use the fixer untill we run out and see how several wash/wear dries go over the next couple of months. Only time will tell.

just to add, we ran into this same issue with matsui white, but we had more of a stencil problem than ink. Our emulsion wasn't exposed properly. we went from an sbq to a dual cure and we hadn't hit the correct expoure time, so that was creating a bit of havoc for us with the dreaded "zombie skin". I know exactly what you are talking about. I bet the temp in the shop didn't help us either. I'll watch the air temp and see where we are when this issue comes up. Hopefully I can try some cci stuff and not worry about it at all.

I talked to my CCI rep this afternoon, and he transferred me to a CCI lab tech in California. Between the two of them, they talked me into trying a gallon of CCI WR25 emulsion. Lab man suspects the ink that picks up under the stencils will be less of a problem than with my Ulano QT Discharge. And I have read good things about WR 25 here and on other forums. So we'll see......

But I ordered some more CCI D-white and both clear bases too, along with the WR 25.
I'm likely going to make the jump soon from Matsui to Sericol for PMS emulations. The CCI D-white is a clear winner over everything else I've tried so far, so I won't buy any more Sericol white.

[Prosperi-Tees]

The WR25 is a great emulsion but I haven't ran anymore than 300 pieces thru it and re claims pretty easy as well.

[Itsa Little CrOoked]

Gerry, does your WR 25 reclaim with a "stringy" texture? That is definitely something I dislike about some of the WB emulsions I've tried. The Ulano QT Discharge doesn't tend to wash off in strings. Some of the others I've tried seem to reclaim better WITH the application of a stencil hardener, which seems counter-intuitive. But without the hardener, they create a drain plugging mass of blue strings.

[Prosperi-Tees]

No strings at all. A few minutes (like 5 or so) in the dip tank and it washes out with ease, never tried manually reclaiming though. The only time I had stringy emulsion was when using a pure photopolymer.

[Itsa Little CrOoked]

Good. I'm anxious to try some. I don't use a dip tank though, and that might be part of my stringy issue with the discharge emulsions I've tried from International Coatings, and Murikami. I just spray the reclaimer out of a squirt bottle reduced
10-1 with water. I like Gemzyme from CCI, and occasionally have used their Microwash II, which is actually a solution designed for dip tank use. It supposedly has an ink degradent along with the emulsion reclaimer. I just haven't tried a dip tank. Maybe I should......

[Prosperi-Tees]

I love the dip tank but I hear it's not so good with roller frames but I'm on static alums. CCI has a great promotion for a dip tank and solution for like $250 bucks. Killer deal

[Homer]

the "stringy washout" or sometimes flaking off of emulsion is typically caused by improper exposure, or wrong emulsion selection for the print method. . .I'm liking the auquasol hv, I'm 99% sold on it for my one pot emulsion. so far so good. I have a gallon of xenon 902qdc and it still feels tacky even when dry. the 925WR sounds good too, I think a ton of guys use that. oh wait, you said CCI, I'm talking Ulano. . .too many damn emulsions to keep track of.

[Gilligan]

Don't forget this database guys... Like Johnny 5 it needs more INPUT!

[ol man]

Had that problem, we mix white with clear base  50/50 or more.... Should help immensely

[Ksports]

Don't forget their Hardener X for long runs on the emulsion. Also CCI has pigment kits for $75. Base, PC, and ZFS is all you need......none of that other stuff. Thin with water. Formulas are taken straight from the Pantone books

Since When?!?! I've pestered my rep about that promised eventuality. Didn't know they had come through....
