dear graeme

thank you for your very prompt help!
yes, now the profile i've created has the perceptual and saturation table
loaded with different information. by the way with a very good result.

when using the rgb profile as an output profile you recommend to use a generic profile,
such as sRGB or a monitor profile, right? is the sRGB profile recommendable in general for
sourcemapping with output profiles or do you also have good experiences with other profiles
such as ColorMatch (using the same D50 illuminant) or AdobeRGB as well?

Unless you specify a source gamut (-S), there will be no separate perceptual or saturation
intent tables (they will use the colorimetric table). You can see this if
you use iccdump, and notice that the offset for the three tags to the
tagtype is the same.
