Digital BW, The Print

Paul,
 
I suppose that MIS Full Spectrum quads densities are very similar - if not
equal - to Piezo, given that these inks are also known as "Cone clone". Am I
right? I have a set on its way to my eager hands, and I was planning to
measure densities as well, but if you already did it I'd definitely trust
your results rather than mine.

To judge ink densities, I print the 21-step test file using what I call my
"Color Test" curve.  (The driver settings I use for this include Matte HW
paper type and No Color Adjustment.) This basically pumps out 100% of each
ink at a different part of the test strip.  Then I scan the test strip and
do a levels on it.  So, black is 100% and white is 0% when measured with the
eyedropper in Photoshop (if the image is in grayscale mode).

Scanner settings, etc. can affect results, so I use the tool just to compare
inks -- and mix new brews.

Piezo gives results as follows: K = 100, C = 84, M = 38, Y = 27%.
