If the intended use of this media configuration is for high quality color output proofing (usage choices: COLOR STANDARD, SPOT COLORS, or COMPROMISE), The paper white of your media configuration should be within 1.5 CIE dE00 of your color standard profile, and the color gamut estimate should be large enough. Proofing quality papers only. Photographic quality papers do not have a stable enough white point (CIE L*a*b* value) for high quality proofing.
If the paper white value is larger than 1.5 dE00, you might want to try a different spectrophotometer measurement condition. (see below). If the measurement condition is correct, and paper white L* is slightly high (less than 1), and b* is slightly bluer (up to 2 units lower) than the target paper white; this can be corrected with a little bit of yellow paper tint. Yellow dots will lower the L* value of the paper slightly and are not visible to the eye. It is not recommended to tint the paper with any other color ink.
