Digital BW, The Print

HI all, new member to the group here!

I currently use a 2200 and EEM for both color and BW. When I bought 
the 2200 it was state of the art and EEM was widely regarded as a 
great paper. Now it has been relegated to the status of proof paper 
and the 2200 is old technology.

Having said that I have been very happy with the results and 
performance of this combo. However I and intrigued by the progress 
made by the technology and and thinking of updating.

I have been considering moving to an 1800 or 2400/3800 and convert 
the 2200 to quadtone and keep it for BW. 

My first question then is whether this still makes sense or have 
things progressed to the point that a K3 printer will give me BW 
prints as good as any quadtone and the quadtone route is no longer 
worth the effort. If quadtone is still worth it, what is the 
currently recommended solution?

thanks and regards

Alistair
