Chromatic Banding

Is it possible to post a pic that shows what you are seeing?

 

Yes a picture is the only way to know if it's banding, stepping, or something else.
A picture of a nozzle test would be helpful too.

 

Some colours band at 6 pass on our 60600.
We run those jobs at 8 pass which mostly fixes the issue.

 

if you are convinced its chromatic banding and not mechanical then its down to several things actual print surface. bed temps. humidity. print speed. print head starting to fail slightly when under a high use.
in a attempt to get the pigments to lay in the correct or similar manor in each direction perhaps lower the bed temp and lower the head speed as its more noticeable one end check the bed temp is equal across the width.

 

Chromatic banding is more commonly related to UV-curing inks than solvent,so pics would help to diagnose.

 

Just to make sure, is the banding in the direction the print head moves, or is it perpendicular? If perpendicular, check the pinch roller tension.

 

Have you tried printing in uni-directional mode to rule out a calibration issue?

solid fields of dark blues...increase pass mode and make sure rail is clean and oiled...

 

I also met the same problem.

 

Anyone else have this issue we have banding on some solid colors.
