One more question for Mark "Ender100" Nelson
Hi Nark,
When you measure a negative for UV or visual opacity are
you simply reading a 100% patch of the digital step tablet printed on the
substrate, subtracting the base density of the substrate?
Thanks,
Don Bryant

The simplest way is to make a 256 step tablet and use the eyedropper tool—look for repeated values on adjacent steps. I agree, if you find you can't get enough density—it is possible you may have to add black as a last resort.. and example of this is the R1800 printer... which for some reason Epson chose not to put an ink configuration setting in the driver.... too bad!

What you say makes sense, but it seems that with some printers you may not be able to get enough density with just the PDN colors, even laying down more ink.
