Digital BW, The Print

Rik,

As a starting point, I measured the print densities of PiezogaphyBW ink from
10 different samples that had been sold to other people.  Using an 1160 and
the older EAM paper, this is what the average densities were when printed
with "No Color Adjustment":

Piezo C = 1.27
      M = .64
      Y = .40

Different printers, papers, etc. can make these vary.  Seeing 1.3 for UT-C
in a 1280 on current EEM is not unusual at all.  That is, the MIS reading
there is close to what most will see for that ink.  The MIS reading that are
off are the LC and LM.  Also, recall that the UT inkset is not the UT2 or
UT7.

It helps a lot. Thanks for the detailed response. I was basing my 
interpretation on the assumption that the numbers in the charts were 
real. It's a bit disturbing, to me at least, that the only published 
numbers for ink densities for either company are wrong, misleading 
out-of-date, or all of the above! And that's before we even start 
talking about fade rates.

It would be good to see somebody compile some up-to-date numbers. 
Paul: it looks like you have the data on-hand. Would you be willing 
to give it a shot?

Thanks again.

Rik
