QTR-Quadtone RIP

To all:
As I understand Jon Cone's message, 3rd Party Ink Carts will no longer be legal or available  
in the US. If this is the case, and using CIS systems are not in the cards for a number of 
reasons, will someone tell me where is one is to get the all black inks for these printers so we 
can continue to us QTR.

I notice that shipping to the US from out of the country is not legal. I suppose in time some 
will do it any way but, I would like to know the answer if there is one.

Thanks any answers to my question,

Jim Otto
