I will update this thread after I make more test prints, but today I received sample packs from Hahnemuhle.
I was disappointed with profiles on Hahnemuhle www - only .icc, without am1x, and in broschure attached to profile info to choose Canon HW Fine Art. At that moment I thought that Canson have it much better, giving am1xes to download.
First print of bull was great, to find any sort of dotting, I had to look hard for it, and found it only because I was trying so hard to find some, and this was with my eyes 5 cm from paper. Totally different quality of picutre than on Canson.
A bit sad, I had much better pricing offer on Canson, I liked papers more - I thought better of company based on my history with their traditional art papers.
Since I spent almost all of Canson packs on tries where I had bad results, I didnt had much left. But I did pick one Rag Photographique duo 220gsm, and print on him using .ICC profile provided by Canson, but chose paper same as for Hahnemuhle, without using provided .am1x. Print was much better, still worse than on Hahnemuhle, but a lot better than before.
Confused, looks like profiles in media configurator can screw up a lot - I'm going to investigate more.
