I'm currently using GIMP for my image work and it has no real CM support
(to come for 2.4). So sRGB is my best bet, IMO.

Thanks, I'll give it a try.

I know that Euroscale Coated is quite old, but a lot of print shops here
still say "Euroskala" on their requirements. In theory, I's use
ISOCoated but in practice, a lot of print shops will look weird at me if
I say it's ISO Coated.

The images are not photographic and some time ago, when I looked into CM
the first time, I decided that rel. colorimetric was the way to go.

Bye&Thanks,
