How many wash/dry cycles and at what temperatures did you do on the white prints? As most printers know, just because it looks good going out the door doesn't mean it stays that way after customers wash and dry them. Especially if they do not follow directions on the tag. My sons baseball team wears maroon jerseys with white numbers. Last year the coach bought new jerseys online for the state playoffs and when we received them in the mail every one looked great printed on 100% maroon poly with white numbers and letters. Not knowing the printer or how bleed resistant the ink was that was printed on them I told all the parents not to wash them but to let me wash them after the game the next day. Oh well, half the parents went home and washed the new jerseys anyway,and you could tell by looking which parents washed and dried according to directions on tags! We had bad bleed to no bleed and everything in between on those jerseys in one day!! I am still going to do a very controlled bleed test since I am set up to do so!!
