"He who marches out of step hears another drum." ~ Ken Kesey
If you are laying them on top of one another right after the dryer, that red ink can bleed into the white due to the high heat they are under.
I had a very similar situation occur and was going to post the same question. It was a small run of hoodies. Two colors, red and white on black Gildan 80/20 hoodies. I ran them on the manual and p-f-p-f the white than p-f-p the red. Both QCM XOLB colors. Everything looked great. I saw a couple of the people from the organization the other night and they were very happy with them, but mentioned the some red got on the white making it look pink. They were not looking for a refund or reprint. Just casually mentioned it and asked if there was something they could do to clean it or if they should bleach it, etc. I am probably going to print them a few new ones to do the right thing. My main question is, "What happened?" I really don't think they were undercured. These came out of the dryer piping hot. I was actually checking for scorch marks because they got so hot. Could an over cured underbase (p-f-p) have caused the top coat to not fully adhere? Everything was great up until they were washed.Thoughts?
He sent me cell phone pics , even though the hoodie is black and I didnt print white on top of red the white text turned pink. BTW they washed them all so theres no fixing any of them now... a reprint would be cheaper than a refund but I have to be honest this is making me want to pack up shop and say screw this crap! That feeling will pass though...
