Digital BW, The Print

Sarah,

hard to tell what's going on from a distance, but here are some thoughts:

- if the breaks are there pre-lin and pre-profiling, then the profiling should 
take care of it (and you seem to have all the right high-end tools for that).
Could they have developed _after_ you did the profile you are using?

- Are all nozzles firing properly, not when you do simple nozzle checks
but at print speed? You have to print with individual nozzles to find out.
Don't know if CBurst allows you to do that or how it deals with the black/gray
vs colors mix. StudioPrint allows that on the PC. 

- Try printing 16bit files. 

- If all else fails, try adding a pinch of noise - the kind that may be
invisible in small amounts. Maybe through a masked layer, to limit
the area it is applied. Whatever you do, do not use blurring - it will
make things worse.

- Generally speaking, using color management to print bw with only
a single gray in the inkset is pretty dicy. I would recommend software
that properly partitions inks and at least one more gray in the set.
