I found that there was no advantage to PK with the UT2 inkset.  So, you'll
find few curve for that ink.  The 2 dark grays do a fine job.

Paul,

Thanks very much for explaining this,I've looked at the curves and I 
see what you mean. And I guess this answers my question about what 
makes the black ink come in with Eboni on glossy paper too - nothing. 
The idea that you could get black without the black ink is somewhat 
counter-intuitive to me!

Best regards,
Ben
