At least with the 1400's 1.5 pl drop, I'm not seeing any reason not to use the Y and LM as toners, which is what I'm doing in the dye inkset I'm now printing with.

The fewer "dimensions" or axes one has to correct, the easier it is.  So, a monotone is the easiest, then a one-toner approach.

Paul, good comments and some I considered too since I wrote that 
message. A ressurection of small gamut may not be worth it but I also 
see a wide variety of custom "quad" inks today, all kinds of curve and 
"profile" adaptions to paper whites and coatings that ask for a devoted 
user or developer, less flexibility when a certain "quad" inkset is 
selected and printing from preferred applications (in my case Qimage) is 
impossible, near impossible or asking for more steps in the proces. I 
like QTR but as I have written a long time ago it would be nice if it 
could function as a normal Windows driver (but still have the 
linearisation etc) so I can hook it up straight to Qimage. Then there 
are several thermal head printers that are nice candidates for "quad" 
solutions but can not be used due to a lack of alternative drivers.

David's and your comment on pigment ink stabilisation is a thing I did 
not worry about enough and should have worried about. Of course I should 
check what printer integrated vibration technology could solve :-) A 
nice coincidence, that other thread.

I expected that a small gamut ink solution today, 8 or 9 channels 
pigment ink; Matte Black, Gloss Black, LK, LLK, Cyan Grey, Magenta Grey, 
Cyan Grey Light, Magenta Grey light, Yellow Grey light, would deliver 
more smoothness, better color consistency, more color toning choices + 
split toning, easier adaption to new papers with profiling and a related 
true soft proof, use of the OEM drivers available and run from preferred 
applications with a wider selection of printers. I do not expect more 
fade resistance than already possible with B&W print modes of the 
different pigment printers.

For 5, 6, 7 channel printers with a reduced inkset skip either easy 
gloss/matte switches or using less grey inks. There is something to be 
said for less ink channels used more evenly so no ink stays long in the 
system.
