Hi ZDannO, Nice to meet you. The problem you have sounds "sort of" like dye migration. This is an effect that is generally seen on shirts containing polyester but it's also happened on cotton shirts on our production floor. In the case of polyester the dyes used for garments don't bind themselves to the polyester. sometimes cotton shirts will do the same thing. This effect can be seen immediately after curing or can appear weeks after the shirts have been delivered. (sucks when it's weeks) Red and Maroon shirts with white ink are the most notorious for this effect but many other combinations can be trouble. Usually this is just the ink turning a shade of the pigment that is already in the shirt. Sometimes I have seen a "halo" effect around the ink but I have never seen it migrate to the back of the garment. Also, you mentioned White ink on a Yellow HBT causing a Bluish haze to appear. That one totally throws me. I have never seen a pigment that is not already in the mix show up. I would seriously call the ink manufacturer back and push harder for an explanation. Ask them if it's their ink that caused the problem. When they say no ask them for proof. If they have seen it happen you can bet they have researched it to cover their butts. While I'm on the topic of inks (we also use Wilflex) When we print on possible migration prone colors we use a low-bleed ink. Wilflex has a nice selection to meet your specific needs. Sorry I can't be of more help. When you do get to the bottom of it please post the information. I am totally curious now. Here is a nice article on impressions that I just found.
