Digital BW, The Print

Martin:

Wasn't this a thread topic earlier this year?

At least for a 4-ink system, I am reasonably convinced that a purge 
print yields representative values.  I am not certain about the 6-ink 
systems (esp the PC and PM position inks). ** I should have expressed 
my uncertainty in my previous post.**  I agree that loading up black 
carts with each of the 5 shades of gray in a hex-set would work well, 
but is a little costly.  I guess it boils down to how accurate the 
results need to be or how the results will be used.  I suppose one 
could also try a smear test (drawing the ink out from heavy 
application to a feather edge on a sheet of paper) for each ink as an 
alternative.
