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.
First, I would suggest that you check and/or replace the maintenance cartridge in case the problem is due to the printheads not being cleaned correctly.
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 :
When printing also add confidence strips left and right to make sure the printheads are firing at their most optimum.
Make sure printheads have been aligned prior to the print to make sure they are at their best.
All nozzles should be firing with no breaks showing in a diagnostic. I would make sure all printheads are within warranty.
If printhead alignment is not fully successful there may be a physical issue in regards to the Maintenance cartridge striking printheads or even the drop detector not working properly.
