Some labs (WHCC, MeridianPro, etc.) provide ICC profiles for soft proofing only, and specify that their profiles NOT be embedded in the image. These labs request either AdobeRGB or sRGB color spaces for the images. Other labs, (i.e. Costco) provide ICC profiles and require that the image color space be converted to the supplied ICC profile. Can anyone explain why the difference? It would seem to me that one way is right, and one way is wrong. I don't understand why it's different based on the lab... Thanks all!
