QTR-Quadtone RIP

Hi all,
Sorry for the cross post, I wasn't sure which group would be the best to offer suggestions on this issue... 

We just set up our 9800 with the k7 inkset and have been starting our test prints. We are running the quadTone rip (in case that matters).

What I'm noticing is a problem with the prints on the edges where the image stops, the ink is bleeding. This is mostly where there is a heavier coverage. So where the image stops on the piece of paper, where it is supposed to be a nice crisp edge, the ink is bleeding and looks like a ragged edge. 

We are printing on hahnemuhle photorag 308, 2880, uni-directional... We also, tried 2880 bi-directional, and 1440 uni-directional - by far, the crispest was the 2880 uni... 

So my question is, has others experienced this? The print itself looks good, no banding, very smooth - just the edges aren't crisp. 

Anyone have any ideas?  

Thanks so much,
Mark
