Trouble with wet on wet waterbased dark shirts
 
Hi all,
I wondering if anyone has experience printing multiple colors wet on wet on a dark non-dischargeable shirt.

Here is the problem we're having...

We're in New Orleans, so we get requests for yellow and green ink on purple shirts. When we have a shirt that does not discharge at all like purple we print a white HSA underbase (like supercover white or cci pure white) then print the colors on top. If we don't flash between every color the first colors lift up because they stick to the back of the next screen. On small runs I don't mind flashing between colors but it kills production speed on larger runs. We've got a system to print wet on wet for shirts that discharge perfectly and one for shirts the discharge just ok but nothing for the shirts that won't discharge. I can do it with plastisol but don't want to go there.

We use CCI's t-charge rfu water based inks and permaset supercover white for our main white.

Is it an underbase problem? Would a different white as underbase work better. We've tried CCI pure white, Matsui White and permaset supercover. They all do the same thing. I can print wet on wet with a mixing white but its just not opaque enough.

Is it my RFU inks? Does anyone print wet on wet with an underbase with any other brands? I've heard that I can get good results with permaset supercover colors and get rid of the underbase but I don't think they have a mixing system to do color matching which is important for us when we're working with schools.

Thanks in advance for your help.

I use 6% by weight of ZFS powder to the DSPCH-1000 and stir until completely mixed.
DSPCH-1000 is a ready-for-use discharge white ink.
ZFS powder is the discharging agent

You seem to be an expert at everything but a lot of the information you are providing in posts is either wrong, irrelevant, or copy & pasted from the internet.

Your reply is not related to the question being asked.

Anyone can Google, and most already have before they post here.

We're looking for original, helpful, thought in the forum. If you're unable to provide that without plagiarizing other sites and representing them as your own thought, it's OK to skip posting a reply to a question and move on to other posts where you can offer original thought.

Using high opacity yellow ink should work.

Failing that, and if available for your ink, you can also try wet on wet additive and only flash the white under-base. To be honest, I've never done this myself, but I've seen it demonstrated. Unfortunately I don't remember by which brand.

We've had luck with Matsui white with some water mixed in for an underbase. It's thinner that straight matsui & you barely flash it. It still has a bite that the ink can adhere to. Are you using Permaset Supercover for your colored ink? Supercover pulls up on the screeen when using it wet on wet? We are usually stuck flashing it. We usually use Green Galaxy for the colors for wet on wet. It is really hard to avoid inks pulling up when underbasing multi-color jobs.

I use Green Galaxy Comet white for an ub on these types of jobs, and we add the GG silicone to mix in the with pigments, it does help with pickup. Also, it takes a few runs to get enough ink onto the bottoms of the screens to not pick up. Im sure you know this, but off contact is a must!
