Digital BW, The Print

I usually see banding with the 1800 when only one ink is firing.  The 
main reason for the 3-MK was that the 1800 needed 3 inks to be firing 
to hide the banding.  A few people have had to go to 3 MKs to hide 
their banding problems.

Frankly, I just put my 1800 in mothballs.  I think I'm done with that 
printer and those carts.  The newer 1400 does not microband 
significantly and has better carts -- totally spongeless.  The latest 
problem with the MIS 1800 carts is that the sponge that is in the air 
inlet appears to deteriorate with Eboni-6, turning it green.  
Enough.  No more 1800 recommendations aside from the 3-MK workflow, 
and even there I'd recommend to those who do not have an 1800 to 
avoid them.  My 1400 was cheaper and does a better job.
