These curves are for the Epson 2400 using the OEM K3 inkset (matte black) to use with Hahnemuhle Photo Rag paper. There are three curves: gray-only, neutral, and warmtone. For each curve there are RGB and grayscale ICC profiles. I've also included the output file from QTR-Create-ICC.exe to give you an idea of the tonal characteristics of each curve.

I've found that printing with the ICC profiles using perceptual intent with BPC enabled gives very accurate results according to the spectro. But when examining real-world prints with my own eyes the shadow tones are just a bit too dark. So for images with deep shadows I recommend keeping the image in qtr-gray-lab.icc profile and adjusting the Gamma slider to +4, which will give a good compromise between accurate midtones and opening up the shadows.
