Martin,

Honest opinion time. Okay???

A - If we deliver you a black with the same performance as the PiezoTone
grays but with a OD that starts slightly less than current competing black
inks, but does not fade and therefore ends higher than them. Would you use
that black exclusively even though at the onset it was paler than current
blacks?

B - If you knew that even another black was available which was slightly
darker at the onset and yet faded to the lower OD of A, but not as
dramatically as PIezoTone black because the starting OD was less, would you
rather use that because after all it is what everyone has been used to?

C - If you choose B, to what degree are you willing to sacrifice non-fade in
order to have better aesthetics at the onset?


D - Would this not be a great poll?
