Dear forum members,
First thank you for all your advice. I went finally to the Epson SC P800 and... ImagePrint!
I have tried Mirage as well as the normal workflow with Epson drivers and OEM papers profiles: first Mirage 4 is not a Rip, just a way to arrange pictures on prints but using Epson drivers and OEM profiles. I did the same with the demo version of QImage.
Second, and I must praise Colorbyte, the new version of their soft (the BLACK version) and the imbedded profiles are incredibly good: easy to use (far more than the old version I had (v8)) and compared to OEM profiles (Canson and Hahnemulhe) IP profiles are just better: I am not an expert doing high level measurements (I do not have the right tools neither the experience), but definitively comparing side by side the prints (same file, same adjustments, same size) the difference is obvious: tonal range, smooth transitions on the darkest part for b&w prints, IP wins.
Yes Imageprint is expensive (at least for a non professional) but how much savings in time and papers, to get right out of the box perfect screen to print matching prints with no pain…
