unesco and Jeff, thanks for the replies. QTR is cheap and if it can provide better results than the Epson driver or ABW then I will certainly give it a try. I will have to try to find some pre-made curves since I do not and probably will not have that capability any time soon. Someone above suggested that there may not be much available for glossy or baryta type paper. This could be a problem. I'm not fond of matte or watercolor type paper for the types of images I'll be printing. I'll do some searching and see what kind of curves I can find.
Jeff, given the cost and your experiences with Piezography I am unlikely to go that route any time in the near future. I trust it is worth it for getting that perfect print but it is just out of reach for me in terms of time, effort and expense. One day I may apply for a grant through our local arts council to do some local documentary work and I might be able to get a new printer and take the Piezography plunge but even that possibility is remote at best.
Alternatively I suppose I could find a lab to do Piezography prints for me. I'd still have to learn the full process I suppose.
In any case, my current goals are to get the i1Display Pro and calibrate monitor, get QTR and experiment with it and the K3 ink set, spend some more time in Capture One to explore its print capabilities vs PS.
