I've done exactly this using the ArgyllCMS
software which is free. You can use the software to prepare either 21 or 51 step B/W patch sets, print them and then read. You do have to know how to run command line software and import things into Excel. I've done QTR ABW profiles for all of the papers I print on and it works quite nice. I would not that I print using the Epson ABW driver and not QTR.
Thanks for your input. I would like to improve my dmax settings when creating my custom curves for QTR. At some stage during the process I need to measure dmax and I was wondering how I do this with the i1 pro? What menu settings and which readouts. I see lots of options for lab CIE etc but no dmax reading? I will check out the software you mention. Can I ask do you get better results with Epson ABW compared to QTR?
