QTR-Quadtone RIP

Tyler,

Out of curiosity, while are you bothering with K3 on x900 if its such a
banding challenge. Why not just use your 9880?

If its to get easy PK/MK exchange - then you should note there is a simple
and cheapish ink swap method for x880. I've used it with my 7880 and it
works just fine. Details here

Cheers,

Mike
