More on 4 colour Vs 6 colour

<x-flowed>Michael Greer has made a very interesting point (started by John 
Heaton - see below), that when you think about it is  more or less a 
punch in the eye for six color (colour) Epson printers. Remember that 
Epson can demonstrate (in the store, or buying point) superior prints 
from six color printers. What they don't tell you, at least from 
Michael Greer's observations, is that this superiority is fleeting, 
enjoy it "quickly" because one of the "extra" colors; ie light 
magenta, will degrade faster than its parent; i.e. "normal" magenta, 
causing color balance to shift in ways the four color printers will 
(probably?) not. Or not as much. It so happens that the "extra" light 
magenta is a key contributor to skin tones accuracy or fidelity. 
Imagine how Pro photographers are going to represent any digital 
prints they give out (sell) to wedding clients, most prints of which 
are going to be heavy on portrait like composures; i.e. faces of 
people. People may be green with envy at times, but not really green. 
If they turn green (on the print), they may also turn angry, and they 
know your address. I am not sure what the picoliter balance is on 
skin tones; percent red, green, blue (or magenta , cyan, yellow) but 
if it contains "some" cyan and yellow, and the magenta fades linearly 
to white, then the skin tone will turn green. And you can't run a six 
color printer with a four color driver.

Maybe Michael can place some pseudo metric qualifiers on his "hold 
out longer" description.
