XC 540 - Interesting Banding, Thoughts?

[razzildazzil]

I'm fairly new to the forum and the signage world (my background is mostly identity design).
Attached is a photo that shows to different print files. both cmyk.
The print on the left is a solid vector color. The print on the right is taken from an image. Both came from Illustrator files.
Any thoughts on why one would contain a substantial amount of banding over the other?
These were printed one after the other, all settings matched.

Also make sure in versa works that even tho the profile is the same, that in the job properties in versa works that the feed calibration is set the same. Either both to "use printer settings" or both to "use profile settings." If they're different, that'd be the obvious fix.

If they're the same, then I don't know

we had similar problems at one point, but only with certain bitmap images.. same image type (usually jpg or tif) but not in every instance. luckily for us the jobs were for signage to be viewed at a distance so never caused problem enough to look in to. Sorry if this isn't much help to your situation, but at least you know it's not an issue isolated to your machine

Good luck!

Problem found! Faulty Damper.

We had a tech come out this morning and found the issue to be a damper that needed to be replaced.
Which is why it was only banding on specific reds.
