Digital BW, The Print

I believe I stated I was using eboni, but it may have gotten lost in the
discussion.
I'm using eboni and UT7 with FS-Y for the light gray ink, in an R200.  The
UT inks are the new base inks.  The eboni Dmax occurs at ~50% ink load, then
turns around.  It gets darker after drying a couple hours, and
insignificantly more overnight.  I'm running the gray inks much lower, ~20%
of max.

With the modified inkset I'm using I have to create the curves totally from
scratch, so I take a fair amount of time characterizing the inks to
determine ink loads and partition densities, before beginning the curve
process.  It would have been much easier with a rip that lets you linearize
each ink prior to curve building, but those rips fully support only the Pro
printers, which I don't have.
A picture of the curves is posted, if anyone is interested.

The spectro data with a* and b* values prior to linearization is plotted

I'm still learning, so comments are welcome.

Best regards,
John Moody

Remember that the relative dmax of papers, as well as other printing
characteristics, often varies with both the printer and the ink used.  Dmax
readings or ratings, for example, might be most useful if they specified the
printer and ink used -- Epson MK v. MIS Eboni.
