And?

Let's try ENGLISH...

A zero gamut monochrome inkset is not necessarily a pigment based 
inkset..  All that means is that the inkset has a single hue...

Where?

Who would ever place themselves in a class with inks that have 
disappearing ink as its cyan component (i.e 1270 inks)...?

It sure would to some extent, but I fail to see shere they say they are 
in the "1270 class"? Even their Fotonics are supposedly estimated at a 
multiple of life of the 1270 inks (exluding cyan - otherwise the 
multiples would be meaningless)..

That is possible..

Sure, but these are tools Robert, not total solutions...

Moderm pigments generally fade less quickly... some exhibit more 
metamerism (2000P anyone?).. But pigments don't yet work well on glossy 
media unless you feel like spraying each print..

That's why I use both..

SG in the 1280...

MIS VM in the 1270...

There is no single answer yet.. Anyone who thinks so is fooling 
themselves.. If you want all the options you run more than one inkset.. 
If not you accept whichever compromise you prefer..

Even EPSONs new "do all" 7 color printer uses different black inks for 
matte and glossy media..
