QTR-Quadtone RIP

Hi Rodrigo

I don't have a 2400 myself (I have an 2100), but perhaps I can answer 
most of your questions.

Actually, this is not the case. The light black and light-light black 
are not neutral themselves. Other ink cartridges are used to get a 
neutral gray. Prior to the 2400 this approach did not work very well. 
The only alternative was to use special gray ink sets. The 2400 has 
been a great breakthrough.

You may get more color inks, but as pointed, you already start with 
color pigments in the first place.
