Can someone identify these press marks? The pressmen are calling them chatter marks. I do not think they are chatter marks but marks coming from a chrome roller for whatever reason. We have monitored the plates for a period of time and also had the Fuji reps. in and there are no indications the marks are coming from the plates. After a few thousand sheets on press they show up and you can see them on the plate. They run in the press direction. They appear to be scratched into the plate and very visible.
