Yep, it's not the easiest thing to use. I think the next version will make things a little better though - I found a bug in the way output curves were being handled in relation to the total ink limit, and this had the effect of putting colprof/collink out of sync with what you could see using xicclu -fif -g. With that fix it seems to be easier to control and get what you want. Graeme Gill.
