I have successfully linearized the K6 remapped curve. This is the last measurement I got.
I suppose that is linear enough. Should I use the curve that gave that measurement? Or, should I run another iteration of linearization on the basis of these measurements, and then use the resulting New Curve to print? That is what I have decided to do…
Then I have made an ICC to softproof (in linear mode) and correct the contrast myself. I have followed the instructions, but there seems to be a problem. I have deleted the Starting Curve data, and kept the Measurements I show above in the PPEv2. Then I have copied and saved the Piezography ICC Profiler data as ti3, and then run it through the application to obtain the profile. Then installed, open in Photoshop and used to soft-proof. I am using it to softproof in linear environment, so Preserve RGB Values on. All good, it shows the predictable loss of shadow depth and contrast. THE PROBLEM happens when I click on “Simulate paper colour”… The image turns black!! The simulate ink colour works as it should: it shows a loss of Dmax. But the simulate paper colour has a problem and turns the image into almost black.
What is happening here? Am I doing something wrong?
I am attaching to this post the measurement data I used to create the ICC, and the resulting data copied from the tab Piezography ICC Profiler data.

Thanks for your help with these two questions!
