I started out using the ICC profiles with piezo inks in an 1160.  
The profiles were far from "excellent" with my printer with blocked 
shadows and poor transitions.  I then upgraded to the iQuads which 
was an improvement but still not perfect.  I still had blocked 
shadows and I was at the mercy of whoever was making my profile.  
When I got a 4000 I could no longer use ICC or iQuads so I opted for 
QTR.  Now I am in control of how the inks are laid down and can 
tweak to my heart's desire.  And my prints are better than they ever 
were before.

With the release of the K7 inks, I hope to be able to vary my tones 
from carbon sepia to neutral by using QTR, customized to however I 
want them to look.  And I can use whatever paper I want, not just 
the ones that have an ICC profile made for them.

Hope that explains why I made the switch.
