Default 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.
