Another cause I have experienced for banding is over-inking. You could try
reducing the ink limits in your curve to see if the banding is reduced.

Another clue to over-inking can be found by looking at your step wedge
through a loupe (or a detailed scan). The edges of black areas (such as the
100% wedge or black text) will show excessive bleeding and/or spatter into
adjacent lighter areas.
