I dont really understand what your problems are or the process you are using....also its "ink" not "paint" printers use ink , painters use paint....with that said..we need to know more info as to what your process is and how you are printing and curing the ink...explain the process step by step and maybe someone will have an answer for your problems..... :)

Can't say about waterbased inks, but with plastisols, if the underbase is overflashed, the top print will often come off in the wash. The ink needs something to grip, and the ink itself is too slick once cured. It could be the same with waterbased. Why not try printing the first color, lightly curing it just enough to keep it from lifting on your finger, then printing the second, then a long cure and a wash test to check? Can't hurt.

Could just be a curing problem. Waterbased inks need the water forced out before they will cure. You should see it steam for a minute or 2 and then die down. The ink will then start to cure. Typically, you need a forced air type of drier to do the job well. I'm not sure a heat press will allow the water/steam to escape. I only do small runs of shirts and use a heat gun to cure my inks which has worked pretty well so far. It's just slow.

Do you apply pressure to the shirt with the heat press, or leave it hovering just above the shirt? How long are you curing?

The opaque inks are pretty thick and take me about 50% longer to cure than the translucent ones. If your layering opaque on opaque, that should take a MUCH longer time to cure than normal.

I have had a few shirts where the top layer of ink has washed off of the underbase, and each time the problem was under curing. A little more time under the heat gun solved it.

your water base is not curing. It needs to air dry before applying heat. Wether it's forced air or simply letting it set. Black is never used for an under base. An under base is like a primer/ undercoat. I thin you just mean your printing black first? For the most part always print your lighter colors first.
