Digital BW, The Print

Today I made my first prints using the MIS/VM inkset on an 1160 with 
CFS carts. My only problem that I have observed is micro-banding that 
is most prominent in the dark tone and low mid tone areas of the 
print. I applied all of the curves created by Paul Roark and the 
problem was evident in all four prints.

How should I try to adjust for the micro banding? This is my first 
attempt at digital inkjet printing so I apologize for what is 
probably a simple question. The paper is Epson matte heavy weight.

Thanks,

Don Bryant
