We facing banding issue on Orange & Magenta color print Branded White Sticker Matte using Latex 360 & 365.
Settings as :- 8P_CMYKcm_90, Temperature 100 Optimizer level 15 and vacuum 30, having horizontal banding, we printed same jobs using same settings 1 months ago. We printed printhead test plot and all nozzle were nice. We try replaced all printheads and test again, but same result.
When we use 10Pass, Both horizontal and vertical banding appear!! I have no idea how it happen. We tried use different RIP ( caldera, onyx and Saiflexi) but doesnt help.
Its doesn't look like normal banding line, more like magenta/ light magenta color lines and color uneven.
OMAS cleaned, Advance calibration, clean platen and clean encoder strip all had done.
Anyone can help? SOS
Same issue here but no solution so far. Hope that HP never ask you increase passes to 12 or 16 for sticker printing. Good luck bro.

Failing that, the User Guide has some guidance on this type of problem (specifically the vertical banding in low-to-medium density areas of solid colour - see Appendix A on page 191.
I would suggest that you try the following :
