anyone here use this? We just tried some, with waterbased on top, and i cannot get the waterbased ink to cure right on top of it. it wipes off!
-
I thought it was just an 80/20 mix of D-Base and D-White? Maybe there's something else in there.
-
I'm pretty sure that the U Base was created for platisol top colors. You may want to contact CCI though it is a new product developed for a customer that does that type of printing.

This is what i'm thinking as well, because i've never had inks come off an 80/20 base before

When I asked them about it they said it was for plastisol top colors.

Wonder where that formula came from :)

The data sheet says it is designed for use with plastisol and water base inks.

We have been using it for a few weeks with excellent results, however, we have been putting plastisol on top of it.

Bit of an old topic, but I was thinking of ordering some of this stuff. Any tips/tricks when it comes to printing/curing etc?
I'm really trying to give this whole softhand plastisol with DC underbase a go as it will appeal to a few of my clients...
-
I literally just got off press from running my first job using U-Base, and think I'll be using a lot of this stuff. The only issue I ran into was a slight shift lighter on the top plastisol colors, specifically red. The customer on this job won't mind, but I have other clients who would. Would a longer flash on the base help to keep the top colors true? I used a quick 2 second flash on this run and my press op pulled the screen down before I could run a quick test.
In any case, this stuff is awesome. Great hand and printability.

Try adjusting how much activator you are using. It messes with red pigment. Also putting down less red plastisol may help (I believe that's what did it for me on a 6 color plastisol on top of discharge base job from awhile ago - 2 passes of the red would end up with an orange ink vs 1 a nice perfect red).

Probably causing it to mix with the discharge more.
Are you printing the underbase like you would regular discharge? Don't need to saturate
the fabric as much, just enough to discharge the surface.
-
I used 5% activator and ran a double hit through 225S. The top screens were also 225S.
Too much all around?
-
Haha probably. You really only need to get that top layer to go. At that point it's like
printing plastisol on a white shirt. We have a lot of problems if we saturate too much
and then flash, the wb adhesive starts getting slimy and giving up the ghost.
-
I'd say based on my dc underbasing in the past that one hit with the 225S should be enough. I like doing top colors with 280 mesh these days, might look at a higher mesh count.
-
We had the problem with the wb adhesive giving up when flashing dc underbase. We found we were overflashing, which causes the discharge to steam and that "slimed" up the adhesive.
Recently tried the CCI DCUB, did not like it. We will continue to mix our own...
-
Mind expanding on what you didn't like and how it compares to the standard 80/20 dbase/dwhite mix a lot of us already use?
-
For us it hung up in the screen, needed a double stroke. The viscosity was jelly like, did not flow well. Lastly we did not like the smell/odor.
-
interesting...
-
Forgot to add we mix 70 base to 30 white 3% activator...

Straight CCI base usually discharges white enough for us to be good for most top colors. Large swaths
of transparent colors or questionable garments and we'll add white. For us, more white = more problems.
