can you give more details on this cause we do a lot of printing that have solid colors, sounds like something useful. we don't have a problem with the banding but better quality sounds awesomeNot whether you've tried this - particularly useful when you see banding, particularly affecting reds.
A tip I was given by NeoFamily:
Not sure if you have already but if you go into the settings and switch it to a microweave 8pass the banding should be gone. Helps with heavy solids but the drawback is it takes almost 1.5x longer to print but quality is improved.
