Digital BW, The Print

Charles, I'm afraid I'm not spending much time on the list any more, but since your problems are using a workflow I've been 
involved with I've watched your posts.
One comment. If truly, nothing at all has changed but the ink batch, and going from carts to CIS, I'd say the new problem has 
to do with one of those two elements. Nothing else makes sense, and that should narrow your troubleshooting 
considerably.
