I'm having a problem with my separations preview. When I turn it on I loose my Tiff previews, off and it's back to normal. see attached Anyone have any sugestions I'm on a good Mac running Monterey with the latest inDesign update. Please help . . .
It looks like white overprint. Export to "pdf for print" and check separation preview in Acrobat.
White overprint would not explain the static lines in the photos, the resizing and streaking pattern of golf balls, and the main burst being reduced and repeated. Something else is going on.
Are all of your links up to date?
Try exporting the file as IDML, in case this is caused by corruption in your INDD file.
A friend of mine had the exact same issue and it turned out to be a permissions issue for him. i.e. a recent upgrade to Monterey reset the permissions to (among others) the Adobe apps. Check System Preferences > Privacy & Security > Full Disk access and see if all your Adobe apps are there and checked.
If that doesn't seem to be it for you, check back!
Those look like the same sort of artifacts som Mac users see on a larger scale when video acceleration is enabled in the prefs. The other reports have not involved separations or overprint preview so that's a long shot, but worth checking.
