Digital BW, The Print

Greetings,

I am printing a B&W still life image of two pears sitting on a sweep of 
watercolor paper. (R2400, ABW, EPSG paper) I notice that there is a 
very light microbanding on the sweep paper area near the bottom of the 
image. It is subtle and the nozzle check is perfect. Is the technique 
to apply some gaussian blur to the area?

If so, can you give me some guidance. Thanks so much!
