Digital BW, The Print

After struggling for days to get a better profile for UT inks on 
PhotoRag. I think I have discovered that the ink set is only capable of 
a 1.34 max density with Eboni Black.

Is this true?

I do not trust my Spectrocam at the highest densities but 1.6 D 
should be possible based on the SpectroCam readings and a Kodak 
greyscale next to it.

I consistently get about 1.7 with Eboni and PhotoRag.  1.34 is about what
the dark gray will be.  The Photo K is almost as weak.

Are you sure you have Eboni there?  

Print a dark gray 100% patch and see how it compares.  (Use the curves with
an RGB 100% patch and turn off 2 of the 3 inks by pulling their curves up to
a horizontal line at 255.)
