QTR-Quadtone RIP

I would check you're printing on the right side of the paper and that 
you have good nozzle checks. Do you get this problem with other papers?

The only slightly odd thing in your curve set up is that black boost is 
less than your black ink limit. Normally it would be slightly more. You 
could also introduce an overlap of say 8-12 to smooth the transitions.
