Sandy,
With the Epson driver you probably can't get more pigment on the film than with just a single K, with the paper type set to the old Archival Matte or Ultra Premium Presentation paper -- whatever they are calling it these days. If you have K in the color spots, their may well be a flat flat spot when the colors cross-over to the K, starting about 75%. In making the curves for Create ICC-RGB, I believe there is also a requirement that at least one of the curves must go the full length (horizontal axis) without the slope getting too low or negative. (Working from old memory here...)
Good luck. I'll be curious what you find works.

Paul,
Thank you for the information. I was hoping to set this up for a friend as an inexpensive printer for making small digital negatives with a simple straight line profile where all curves follow the K. If I can find an inexpensive way to fill all the cartridges with black ink I may try running it with the Epson driver and embedding an icc with the QTR Create-ICC-RGB as you suggest. That might actually be easier for the friend to use.
