The software uses the measurements from the Single Channel Ink Limit chart to compute initial gamut statistics. It compares the results to historical data for each Usage Type, and computes a "PASS" or "Warning" answer. A pass indicates that initial data looks good for this media configuration, so it is recommended to continue. If a "Warning" is computed, it is recommended to take a few minutes to make sure you have selected the right components in this media configuration. see questions below. You can always choose to continue, no matter what the gamut results are.
Estimated Media Config parameters:
...
(3) low gamut volume - the estimated Gamut Volume is too small for compared to your Target Profile, with the selected usage.
(4) poor 2color overprint C* - the 2-color overprint CIE C* estimated value is too far from your Target Profile.

Target Profile Results: (PminL*: 9.05), (pMYC*: 83.23), (pCYC*: 70.93), (pCMC*: 50.18), (Pmaxa*: 75.0), (Pmaxb*: 92.99), (Pmina*: -66.0), (Pminb*: -46.02), (estProfGamutVolumeDiff: 1060811), (estSpotGVolumeDiff: 147626)
Troubleshooting a Gamut WARNING message:
Did I choose the right Media / paper?
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 13.5 0 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* valuevalue) for high quality proofing.
If the paper white value is larger than 13.5 0 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 (up to 1 unit higher), 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.
