This questions is related to Why did LR6 soft proofing thought some colors were out of gamut even if they turned out perfect?
Since I found out some of my images are out of gamut of the printing ink+medium I plan to use, I would like to compare
- the gamut of my monitor with the gamut of my printing ink+medium to understand which colors are critical and the amount of the difference in gamut for those colors, without using try and fail by working on my photos
- the gamut of two different printing media to choose the one that best suit each photo
Needless to say that I have ICC profiles for monitor and ink+media.
Is there a free software to compare gamuts? Windows in particular, Mac would be welcome too. A graphical comparison would be the best choice, since the gamut is a 3D (at least) color space.
