Did you Try and flash and second hit the colors?
thanks will try that. Apparently I have been told that sericol have a product which you lay as the under base which kind of limits the migration. I will contact them and find out - it is some kind of gelWe just did a large run of white plastisol on camo tees. It took quite the manipulation and experimentation to minimize the dye migration. We were able to eliminate MOST of it, but it was still slightly apparent. The best results we got happened with the lowest temp and quickest flash times - really, just barely enough to gel cure the white underbase. Nice thick ink deposit, and then as fast and quick a thorough cure in your dryer that you can get after the second plastisol hit... Just keep in mind that it's the heat that is making the dye migrate out of the shirt and into the ink, so focus on getting it cured, but not getting it too hot...
what brand of waterbase? we use matsui. i tried white discharge underlay, yellow plastisol on top. the discharge didnt work well, looked worse than a poly plastisol test... 100% anvil camo...I use waterbased to print on camo t-shirts and have encountered no problems whatsoever.
