Roy,

I posted a scan of the 21 step gradient in the files section (7000_NK6_21Step.tif). You can 
see the graininess in the scan in the 25-40% range easily. In the actual print it goes right 
up through 95%. I'm 55 and can see this clearly with only my reading glasses. Through a 
loupe it gets pretty alarming. I know the 2200 has a smaller dot, but I've seen much 
smoother results on a 7000 with only 4 inks than I'm getting here with 6.

Nozzle checks are good. As I noted, I replaced the heads last week so I've done lots of 
adjustment and nozzle printouts in the last 7 days. The inks are in the right slots, now. I 
got them wrong at first and have them placed correctly at this time.

I've tried making my own profile from scratch and the result is better. I found that density 
increased through 70% in the inkseparation file, so I upped my ink limit to 65%, removing 
the varying limits for the other inks.

Again, any help is greatly appreciated
