Digital BW, The Print

Would this work ?

1) Buy either 110 or 220 K3 inks - 7 inks (Photo K, Matte K, Light K, 
Light Light K, LM, LC and Y)

2) Syringe ink into MIS refillable carts.
3) Use QTR or IJC/OPM to control the inks.

Result K3 inks in a 2100 able to print using Photo K or Matte K with 
no waste, and tonable using LM, LC and Y inks.

Anyone tried getting ink out of these bigger carts? It seems to me 
that it would be worth the hassle on cost alone. 2100 carts 13 ml £10 
approx, 220 ml carts £55 approx. Usable ink in the 13 ml carts 
probably more like 10 ml !! 

I have used the MIS refillable carts with great success and once 
primed there is then no further waste.

Crazy idea or not?

Peter.
