QTR-Quadtone RIP

In answer to the earlier suggestion, I printed out the QTR calibration ramps onto Epson Premium Presentation Matte with the Cone K6 ink.  After letting them dry for 2 days I measure the black ink using a Datacolor #1005 Spectrocolorimeter.

The black ink quickly ramped up to around d=1.46 by about 50% load and tapered off after that finally reaching d=1.53 at 95% load.

Does anyone have any experience with this combo that can say "yeah, that's about what to expect" or "no, you should get higher than that"?

Does anyone want to share what Dmax they get with other papers using the K6 inks?  Especially those that have Cone profiles for the 1280 included in the QTR distribution.

Regards,
Mike

While it was out I played around with using QTR on my Epson R1800 with regular OEM inks to make B&W prints.  The Dmax of the Epson inks was no doubt higher than the Cone inks so maybe I simply need to readjust my expectations.

What I'm getting now still has that nice linear curve that can deliver detail in the shadows and highlights.  I just wish the pure black was a little "blacker".

Since you already have QTR, it might be worth printing the "calibration chart" at 100% ink limits to see if your specific printer is well matched with the supplied K6 curves. You should measure the black ink densities to see where it maxes out, and compare that number with the K6 curve Dmax.
