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.
