I have an R1800 using MIS color inkset (refillable carts) and want to use this to make B/W prints on a couple types of HP roll paper (2 glossy and 1 matte).  I get leftovers from our department's large format printer, so that's why the "non-traditional" paper.  I've downloaded and looked at QTR and read a few articles on how to use the package for creating custom curves and ICC profiles.  I've seen where someone suggested using Qimage to "print to file" (tiff output) and then use QTR GUI for printing, while others print directly from Photoshop, but before I get to printing anything, I think I need to "profile" my ink/paper combination, and I'm not quite sure where to start and what settings to use. 

I assume I need to do the calibration steps to create curve files for my various papers and then linearize them.  I have a ColorMunki to read patches and make the appropriate settings for ink limit and relative ink density.  I've also looked at Keith Cooper's article at Northlight Images about using the Colormunki to assist in the linearization and generate an ICC profile.  Should I do the QTR calibrations first, and then go on to the ICC profile generation?  I assume so, but then what settings do I use in the printer?  Should I print the wedge pattern for Munki scanning from Qimage of from QTR GUI?

I realize that not using the 3-black ink system (MK, LMK, LLMK) will not give the best results, but all I'm really looking for is something better than what I'm getting from my ColorMunki profiles for this ink/paper combination.  I don't expect "professional" quality prints, but I'm pretty sure I can do better than what I have now.  If anyone out there can shed some light on this I would be very grateful.  If anyone has gone through this procedure with an R1800, I would appreciate hearing about how you set things up for using QTR.

Thank you in advance.
