That's an understatement! The grays *are* green.

I believe the green cast is not entirely a function of strict linearisation,
as I like to think of it. It is a tricky combination of a deficient ink
formulation and some fluorescence effect, IMHO. Producing neutral grayscale
with this printer, irregardless of media, is quite a challenge.
Otherwise, it's a wonderful printer for the money and the RIP is decent,
although it could be improved. But the sharpness and level of detail in the
image is impressive.
