Thank you for the answer. What I don't understand is the results whit absolute intent: why the intersect in sRGB is bigger than Adobe RGB?

Can you post the command lines and outputs of iccgamut and viewgam?

Do you interpret the numbers correctly?

Example:

$ viewgam -i sRGB.gam printer.gam out.wrl
Intersecting volume = 512354.4 cubic units
'sRGB.gam' volume = 833600.9 cubic units, intersect = 61.46%
'printer.gam' volume = 552445.5 cubic units, intersect = 92.74%

$ viewgam -i AdobeRGB1998.gam printer.gam out.wrl
Intersecting volume = 552205.4 cubic units
'AdobeRGB1998.gam' volume = 1209985.9 cubic units, intersect = 45.64%
'printer.gam' volume = 552445.5 cubic units, intersect = 99.96%

This means that

• the printer can reproduce 61.46% of the sRGB gamut
• the printer can reproduce 45.64% of the Adobe RGB gamut
• sRGB can reproduce 92.74% of the printer's gamut
• Adobe RGB can reproduce 99.96% of the printer's gamut
