I tried out a new printing lab and received some test prints from them. After calibrating my monitor I compared the prints to the images on screen and they looked very close in color (though not quite perfect). I then downloaded their ICC profile and when I did a soft proof using it, the colors were WAY off...totally unsaturated. Maybe I don't need to worry about it since I was happy with the test prints, but I do want to understand why this might be the case. Any ideas of what could be going wrong?
