Maybe I'm misinterpreting your post, but I think you're confused about how colour profiles work.there isnt any colours that are effected its only the white area's.
and i used there ICC colour profile of there site, that there printers use. so there should not be a problem there.
remember, i had 3 A3 prints, same profile. but all was fine!
all the A2's are messed up, (different printer)
Just because you have assigned your chosen profile to the image, that doesn't mean that the printer will be able to reproduce it. You still need to proof your image against a suitable ICC profile for that printer (and paper) to ensure that all your colours will be reproduced as intended.
Are you 100% sure it's white? Anything other than #FFFFFF will require the printer to lay down at least some tint over the paper to produce what you want.and all the white area's was solarized. so nothing to do with me.
Maybe it's just one of those things and the next run will be fine, but I still think that it's a gamut issue with that Polielettronica printer.
