Banding in print

I am using the versa-camm sc545-ex with flexi. How do I get rid of banding in the print. Also what icc profiles do I need to use to get my colors to be exactly like they are supposed to be. Can anyone give a direction to take?

you're using a low quality pass, like 4 pass in your printer, use 8 or 12 passes high quality and you got to know the profile ICC, your material, it has a profile matching, but used 8 or 12 passes and banding will disappear
